Posted on by Armor Lubricants

engine oil weights guide

Whether you just heard the term engine oil weight and want to know more, or want to understand the difference between 10W30 and 10W20 for your car engine, you are in the right place.

What are Engine Oil Weights and How are They Determined?

Oil weights represent an oil’s viscosity, or its resistance to flow, under different temperatures. The Society of Automotive Engineers (SAE) classifies motor oils using a numerical system that indicates how the oil behaves in cold and hot conditions.

Manufacturers determine oil weights through standardized tests that measure how the oil flows at different temperatures. The lower the number before the “W” (winter rating), the better the oil performs in cold starts. The second number represents the oil’s viscosity at operating temperature, affecting lubrication and engine protection.

What Do the Numbers in Oil Weights Mean?

The numbers in an oil weight, such as 10W30, indicate its multi-grade viscosity rating:

  • “10W” (Winter Rating) – The oil remains fluid in cold temperatures, allowing smooth engine startup. Lower numbers, like 5W, perform better in extreme cold.
  • “30” (Operating Temperature Rating) – The oil maintains a stable viscosity when the engine reaches its normal running temperature. Higher numbers, like 40 or 50, provide thicker protection for high-performance or heavy-duty engines.

10W30 Engine oil has Different viscosity in different temperatures has Different viscosity in different temperatures.  Typical (Approximate) Kinematic Viscosities for 10W‑30 are usually like the following:

At 100 °C (212 °F):

  • SAE Spec Range: 9.3–12.5 cSt
  • Typical Product Data: Around 10–12 cSt

At 40 °C (104 °F):

  • Usually in the range of 60–80 cSt (typical data sheet values; can be a bit higher or lower depending on the formula)

(Valus change for different products and we presented average number for educational purposes only). 

How Does Viscosity Affect Engine Performance?

Viscosity can literally translate into the resistance of flow! Based on such definition it is safe to say higher viscosity means thicker oil that takes longer to flow to engine components. On the opposite side, lower viscosity indicates smoother flow.

Based on what we said it is logical to switch to lower viscosity right? NOT ALWAYS

Although it is great to have smoother flow and, reducing viscosity excessively jeopardizes lubrication. Oil needs to be thin enough to flow fast and thick enough to create a protective layer between moving parts keeping a constant layer between moving parts.

We can say oil viscosity impacts several critical aspects of engine performance:

  • Cold Start Protection– Lower viscosity oils, like 5W-30 oil, flow easily in cold conditions, reducing startup wear.
  • High-Temperature Stability– Higher viscosity oils, like 10W40, resist thinning at high temperatures, ensuring proper lubrication under heavy loads.
  • Fuel Efficiency– Thinner oils reduce friction, improving fuel economy, while thicker oils provide extra protection for high-performance engines.
  • Wear Protection– The right oil prevents metal-to-metal contact, reducing wear on engine components over time.

Which Engine Oil Weights Are Recommended for Different Engine Types?

Different engines require specific oil viscosities to function optimally:

  • Passenger Cars & Light Trucks – Most modern vehicles use 5W30 or 10W-30 for balanced protection and efficiency.
  • High-Performance Vehicles – Sports cars and performance engines benefit from 0W40 or 5W50 for extreme temperature stability.
  • Heavy-Duty & Diesel Engines – Trucks and machinery often require 15W40 or 20W50 for enhanced wear protection under heavy loads.
  • Cold Climate Vehicles – Cars in freezing temperatures perform better with 0W20 or 5W30 to prevent thickening in cold starts.

(Disclaimer) Please check your vehicles manual and engine’s cap before changing engine oil.

How to Choose the Correct Engine Oil for Your Vehicle?

The correct engine oil for your car is the one specified by your car manufacturer (you can find the correct weight in the manual or on the engine cap under the hood). When the manual is not available, you should select engine oil based on various factors, including viscosity, climate and driving conditions.

What Factors Should You Consider When Selecting Oil Type?

Choosing the right engine oil involves evaluating several key aspects:

  • Viscosity Rating– Oils like 10W30 or 5W30 provide different levels of flow and protection under various temperatures.
  • Driving Conditions– Vehicles exposed to heavy loads, stop-and-go traffic, or extreme temperatures may need a different oil grade than those used for highway driving.
  • Engine Age and Type– Older engines may require thicker oils to compensate for wear, while modern engines perform best with low-viscosity synthetic oils.
  • Oil Additives– Some oils contain detergents, anti-wear agents, or friction modifiers to enhance protection and efficiency.

Considering these factors helps in selecting an oil that maintains optimal lubrication and performance in all conditions.

What Does the Manufacturer Recommend for Your Car?

Manufacturers specify the ideal oil viscosity and type for each engine. Checking the owner’s manual provides:

  • The recommended SAE viscosity grade (e.g., 5W30, 10W40)
  • Whether the engine requires synthetic, semi-synthetic, or conventional oil
  • Approved API (American Petroleum Institute) and ACEA (European Automobile Manufacturers Association) standards

Using an oil that meets the manufacturer’s specifications prevents engine wear, overheating, and reduced fuel efficiency. Vehicles with turbocharged or high-performance engines often require synthetic oils for better protection under extreme conditions.

How Can Oil Weight Affect Fuel Economy?

The viscosity of engine oil plays a direct role in fuel efficiency:

  • Lighter Oils (e.g., 0W20, 5W30)– Reduce internal friction, allowing the engine to run more smoothly and consume less fuel.
  • Thicker Oils (e.g., 10W40, 20W50)– Provide better protection in high-performance or older engines but may slightly increase fuel consumption due to added resistance.
  • Multi-Grade Oils– Balance cold start protection and high-temperature performance, optimizing both fuel efficiency and engine longevity.

In Conclusion

Selecting an engine oil for ultimate engine protection with the right balance of viscosity helps improve fuel economy while maintaining engine durability and performance.

essential guide to upgrade diesel engine performance and boost power

How to Upgrade Your Diesel Engine to Boost Performance and Improve Power?

You know that feeling—the one when you press the pedal, expecting a surge of power, but instead, your truck hesitates, lagging like it just woke up from a nap.

Maybe you’re towing a trailer up a steep incline, trying to overtake a slow-moving car, or just looking for that extra punch when you hit the open road. Whatever the case, your diesel engine should be delivering smooth acceleration, raw power, and solid fuel efficiency. But here you are on the road, feeling frustrated about performance drop.

Can you buy another diesel truck? Sure, you can, but where is the fun in that when you can fix your old one?

Engines are not meant to last forever, but they are also made to last long! Longer life span comes with some drawbacks, like performance drop, but here’s the thing—you don’t need a full engine rebuild or a high-budget turbo upgrade to bring it back to life.

Few smart tweaks can sometimes to unleash the hidden power under your hood. Let’s dive into how you can take your diesel engine performance to the next level.

Electronic Control Module (ECM) Reprogramming

Every modern diesel truck relies on an Electronic Control Module (ECM) to regulate engine performance. This tiny computer controls fuel injection timing, air-to-fuel ratios, and boost pressure. While factory settings prioritize fuel economy and emissions, reprogramming the ECM—also known as tuning or reflashing—can unleash serious power.

How Tuners Improve Diesel Performance

A tuner or ECM reflash adjusts fuel and air delivery parameters, allowing your engine to burn fuel more efficiently. This optimization results in:

  • Increased horsepower and torque
  • Better throttle response
  • Improved fuel efficiency (depending on the tune)
  • Reduced turbo lag for quicker acceleration

Some tuners focus on power, while others prioritize economy or towing performance. Many offer switchable modes, letting you adjust power levels based on your driving needs.

How Much Power Can You Gain?

Horsepower gains depend on the tuner and the level of modification. Most diesel trucks see an increase of 50 to 200 horsepower with proper tuning. High-performance tuners can push even higher, but excessive power gains may require supporting upgrades to maintain drivetrain reliability.

Choosing the Right Tuner

Several brands dominate the diesel tuning world, each offering different features and tuning strategies. Popular options include:

  • Banks Power– Reliable, emissions-compliant power gains
  • SCT– Custom tuning for Ford diesel engines
  • Edge– User-friendly tuners with real-time monitoring
  • EFI Live– Advanced tuning for Duramax and Cummins engines
  • TS Performance– Simple plug-and-play power modules
  • Bully Dog– Versatile tuners for multiple diesel platforms

Important Considerations Before Tuning

  • Transmission Upgrades– Boosting power beyond 150 horsepower may stress your transmission, requiring a stronger torque converter or built-up internals.
  • Emissions Compliance– Some tunes disable emissions controls, which may not be legal in all areas. Look for emissions-friendly options if needed.
  • Engine Longevity– Aggressive tuning increases stress on engine components. Pairing tuning with proper maintenance and high-quality diesel engine oil helps protect against wear.

Turbocharger Upgrades

Turbochargers are the heart of a diesel engine performance, forcing more air into the combustion chamber to produce greater power and efficiency. More air means more fuel can be burned, translating into higher horsepower, stronger torque, and better throttle response.

Learn about key steps to maintain internal combustion engine in this informative blog post.

Why Stock Turbochargers Fall Short

Factory-installed turbos are designed for balanced performance, not peak power. While they work well for daily driving, they often struggle with aggressive tuning, heavy towing, and high-speed demands.

Excessive heat buildup, limited boost capacity, and restrictive airflow can hold back your engine’s full potential. Upgrading to a high-performance turbo eliminates these limitations, delivering faster spool times, improved airflow, and sustained power under heavy loads.

Choosing the Right Aftermarket Turbo

Not all turbochargers are built the same. Selecting the right one depends on how you use your truck:

  • Towing and Heavy Hauling– Opt for a larger variable-geometry turbo (VGT) for steady boost and low-end torque.
  • Racing and Performance Builds– A high-flow single or compound turbo setup delivers extreme horsepower gains and rapid acceleration.
  • Daily Driving– A mild turbo upgrade improves fuel efficiency and throttle response without sacrificing reliability.

Fuel System Enhancements: More Fuel, More Power

A diesel engine is only as powerful as the fuel system feeding it. Without a steady, high-pressure fuel supply, performance suffers- resulting in sluggish acceleration, lower horsepower, and inefficient combustion. Upgrading key components like lift pumps, high-pressure pumps, and injectors ensures consistent fuel delivery and unlocks hidden power.

Key Fuel System Upgrades for Performance

  • Lift Pumps– Maintain a steady fuel flow, preventing air pockets and fuel starvation under heavy loads.
  • High-Pressure Fuel Pumps (CP3 & CP4)– Deliver precise fuel pressure for efficient combustion. The CP3 pump is known for reliability, while the CP4 pump has a history of failure due to modern diesel’s lower lubricity.
  • Upgraded Injectors– Larger injector nozzles increase fuel volume, allowing for a more powerful and efficient burn. This results in better throttle response and higher horsepower gains.

Protecting Your Fuel System from Damage

  • Fuel Additives– Diesel fuel today has lower lubricity, leading to premature wear on components like the CP4 pump. Using high-quality diesel additives reduces friction and extends fuel system lifespan.
  • Regular Maintenance– Replacing fuel filters and monitoring injector performance prevents clogging and ensures consistent power delivery.

High-Flow Exhaust Systems: Let Your Engine Breathe

A diesel engine is like an athlete—the easier it breathes, the better it performs. Stock exhaust systems often restrict airflow, causing backpressure that limits power and efficiency. Upgrading to a high-flow exhaust system removes these restrictions, allowing exhaust gases to exit freely and improving overall diesel engine performance.

How a Performance Exhaust Boosts Power

A high-flow exhaust enhances diesel engine performance by:

  • Reducing Backpressure– Less restriction means the turbo spools faster, improving throttle response and horsepower.
  • Increasing Engine Efficiency– Exhaust gases exit more smoothly, reducing heat buildup and improving fuel economy.
  • Enhancing Sound & Aesthetics– A performance exhaust delivers a deeper, more aggressive exhaust note while giving your truck a custom look.

Key Considerations Before Upgrading

A high-flow exhaust is crucial when adding tuners, turbo upgrades, or fuel system enhancements. Without proper exhaust flow, increased power output can lead to excessive heat buildup, reducing engine longevity.

When choosing an exhaust system:

  • Material matters– Stainless steel resists corrosion better than aluminized steel.
  • Pipe diameter affects flow– Larger diameters (4” or 5”) support high-horsepower builds.
  • Muffler design influences sound– Straight-through mufflers increase flow and provide a more aggressive exhaust note.

A high-performance exhaust unlocks extra power while keeping engine temperatures in check, making it one of the best upgrades for serious diesel enthusiasts.

In conclusion

Upgrading your diesel engine can significantly boost its performance and power. Remember to choose high-quality lubricants offered by Armor Lubricants to protect your engines.

How long does 100% synthetic oil last?

The lifespan of 100% Synthetic Oil depends on driving conditions, engine type, and manufacturer recommendations. Compared to conventional and full synthetic oils, 100% synthetic formulations offer longer drain intervals and superior engine protection.

Typical Oil Change Intervals

  • Standard driving conditions: 10,000 to 15,000 km (6,000 to 10,000 miles)
  • Severe driving conditions: 8,000 to 12,000 km (5,000 to 7,500 miles)
  • Extended-performance synthetic oils: Up to 24,000 km (15,000 miles) with proper filters

Many high-performance 100% synthetic oils are designed for extended drain intervals, reducing maintenance frequency while maintaining engine cleanliness and efficiency.

Factors Affecting Oil Longevity

  • Driving habits: Frequent short trips, stop-and-go traffic, and high-speed driving increase oil degradation.
  • Engine type and condition: Turbocharged and high-performance engines generate more heat, requiring more frequent oil changes.
  • Environmental conditions: Extreme temperatures and dusty environments can shorten oil life.
  • Oil quality and specifications: Premium Group IV (PAO) and Group V (ester-based) synthetic oils provide the best longevity and performance.

Following the vehicle manufacturer’s recommendations ensures optimal performance and longevity. Regular oil analysis can also help determine the best change interval based on your specific driving conditions.

What are the disadvantages of fully synthetic oil?

While Fully Synthetic Oils offer superior engine protection and performance, there are some drawbacks to consider before making the switch. These factors may influence whether 100% Synthetic or Full Synthetic Oil is the best choice for your vehicle.

1. Higher Cost

Fully synthetic oils are significantly more expensive than conventional or semi-synthetic oils, often costing two to four times as much. The advanced refining processes and high-quality base stocks contribute to this price difference. For budget-conscious drivers, this higher upfront cost can be a concern.

2. Potential Compatibility Issues with Older Engines

Vehicles manufactured before the 1990s may not be designed to handle synthetic oils. Fully Synthetic Oils have stronger detergent properties, which can dissolve built-up deposits that previously acted as seals, potentially causing oil leaks in older engines. Classic car owners should consult their manufacturer before switching.

3. Environmental Considerations

The production of synthetic oils requires more energy and resources compared to conventional oils. While they last longer and reduce oil change frequency, their manufacturing process has a higher environmental impact due to increased refining and processing.

4. Potential for Additive Separation

Synthetic base oils require carefully formulated additive packages to achieve optimal performance. If not properly blended, certain additives may separate, reducing the oil’s effectiveness. High-quality synthetic oils from trusted manufacturers use advanced formulations to prevent this issue.

Should I Avoid “Fully Synthetic”?

The term “Fully Synthetic” is widely used in the lubricant industry, but it doesn’t always mean the oil is made entirely from 100% synthetic base stocks. Some manufacturers use this label for oils formulated with Group III, Group IV, or Group V base oils, creating confusion for consumers.

Why “Fully Synthetic” Isn’t Always 100% Synthetic

  • Many oils labeled as “Full Synthetic” contain Group III base oils, which are highly refined mineral oils rather than truly synthetic formulations.
  • Some manufacturers do use Group IV (PAO) or Group V (esters) in their “Fully Synthetic” oils, making them equivalent to 100% Synthetic Oil, but this isn’t always the case.
  • Regional regulations allow Group III oils to be marketed as synthetic, making it harder to distinguish between highly refined mineral-based synthetics and truly synthetic formulations.

Is 100% Synthetic Oil Always Necessary?

  • 100% Synthetic Oil (PAO or ester-based) offers exceptional performance, thermal stability, and oxidation resistance, making it ideal for high-performance vehicles and extreme conditions.
  • Full Synthetic Oil made from high-quality Group III+ or a blend of Group IV and Group V oils can still provide excellent engine protection for most vehicles.

Rather than avoiding “Fully Synthetic” oils entirely, it’s better to check the oil’s formulation, industry certifications, and manufacturer specifications. High-quality Full Synthetic Oils with PAO or ester content can offer near-identical performance to 100% Synthetic Oil, making them a practical and cost-effective choice.

In Conclusion

Choosing the right engine oil depends on you vehicle’s specific needs and your budget. By understanding the key differences between full synthetic oil and 100% synthetic oil, you can make a right decision that benefits your engine’s performance, protection and longevity.

Why Modern Engines Use Lower Viscosity Oils Like 0W-20

Posted on by Armor Lubricants

modern engines use lower viscosity oils

SAE 0W-20is now the best seller engine oil grade but 10 years ago supplier used to have more demand for higher viscosity grades such as 15W40 or even 20W-50.

What happened during the last decade to cause this switch? Engines became smaller.

The Shift Toward Lower Viscosity Oils

The Shift was not sudden but actually gradual! researchers has been working for years to enhance engines and provide better performance at lower cost. Changes in engines specifications must always be followed with parallel changes in lubrication requirements.

Fuel Economy and Engine Efficiency

Modern engines prioritize fuel efficiency, leading to a greater reliance on low-viscosity oils. Engineers develop downsized, high-compression engines that generate more power from less fuel, improving overall mileage. Achieving higher efficiency requires reducing internal friction, which is possible with thinner lubricants that move easily through tight engine clearances.

Low-viscosity oils help reduce energy losses by minimizing resistance between moving parts. Automakers focus on advanced engine designs, such as direct injection and turbocharging, which demand oils that support smooth operation and optimal fuel consumption.

Improved Lubrication in Tight Engine Tolerances

Advancements in engine design have led to tighter clearances between components, demanding fast-flowing lubricants to prevent metal-to-metal contact. Modern engines use precision engineering to achieve maximum efficiency, meaning traditional thick oils struggle to reach narrow oil passages quickly.

Low-viscosity oils flow immediately upon startup, reducing wear and protecting components from excessive heat and friction. In turbocharged engines, efficient lubrication is even more critical, as high temperatures and rapid spool speeds require oil that circulates quickly without excessive resistance.

OEM Recommendations and Industry Standards

Automakers rigorously test and specify motor oils that optimize performance, longevity, and efficiency. Industry standards such as API SP and ILSAC GF-6 focus on reducing deposits, improving fuel economy, and preventing low-speed pre-ignition (LSPI)—a common issue in modern direct-injection engines.

Newer engine technologies, including hybrid powertrains and stop-start systems, also benefit from low-friction oils that enhance durability under frequent restarts. Manufacturers align their oil recommendations with these advancements, ensuring that engines operate at peak performance while maintaining longevity.

2. Performance Benefits of Lower Viscosity Oils

Tests and inspections show that using lower grades oils on modern engines keeps performance high.

Faster Cold-Start Protection

Cold starts put significant stress on an engine, especially in modern designs with tighter tolerances. When an engine is first started, oil must quickly reach critical components to prevent metal-to-metal contact. Low-viscosity oils flow rapidly at low temperatures, reducing friction and wear during startup.

Engines equipped with stop-start technology benefit even more from fast-flowing lubricants. Frequent engine shutdowns and restarts demand oil that can circulate instantly, preventing excessive wear on bearings, camshafts, and other essential parts.

Enhanced Thermal Stability

High-performance engines operate at elevated operating temperature, requiring lubricants that resist breakdown under extreme conditions. Synthetic low-viscosity oils maintain stable viscosity and protective properties, even under high loads and intense heat.

Advanced engine technologies, such as turbocharging and direct fuel injection, generate more heat than traditional designs. Oils with superior thermal stability help prevent deposits, sludge formation, and viscosity loss, keeping engines clean and efficient over extended service intervals.

Compatibility with Advanced Engine Designs

Modern engines rely on lightweight materials, precision engineering, and high-pressure fuel systems to maximize efficiency. Low-viscosity oils complement these advancements by reducing friction and maintaining proper lubrication in narrow oil passages.

Turbocharged and hybrid engines, in particular, depend on optimized lubrication to handle rapid temperature fluctuations and frequent load changes. Using the right engine oil allows these engines to perform at their best while minimizing long-term wear and tear.

3. Common Concerns About Using Lower Viscosity Oils

Is Lower Viscosity Oil Too Thin for Engine Protection?

Many drivers worry that thinner oils may not provide enough protection, especially under high loads or extreme temperatures. However, modern synthetic formulations contain advanced additives that enhance wear protection, reduce deposits, and maintain stability over long service intervals.

Newer engines are designed with precise oil distribution systems that rely on low viscosity to lubricate critical components efficiently. Engineers optimize bearing surfaces, piston clearances, and valve timing systems to work seamlessly with modern lubricants, ensuring durability without compromising performance.

Can Older Engines Use Low-Viscosity Oils?

Engines designed for higher viscosity oilsmay not perform well with thinner lubricants. Older models often have looser tolerances and different sealing materials, which may lead to increased oil consumption or reduced film strength if the oil is too thin.

Manufacturers specify oil viscosity based on engine design, so switching to a lower viscosity oil in an older engine should only be done if recommended. Using the correct lubricant helps maintain proper compression, wear protection, and overall longevity.

Do Low-Viscosity Oils Require More Frequent Changes?

High-quality synthetic oils with low viscosity are engineered for extended drain intervals, resisting breakdown and oxidation over time. Advanced detergents and anti-wear additives help keep engines clean, even under demanding driving conditions.

Following OEM service recommendations is essential for maintaining engine health. While some high-performance or high-mileage engines may require shorter oil change intervals, most modern engines benefit from longer-lasting lubrication with improved efficiency.
