Why Choosing the Right Motor Oil Matters

Motor oil does more than lubricate moving engine parts. Modern engine oil helps control heat, reduce friction, prevent sludge buildup, and protect internal engine components during daily driving.

Using the proper oil can help:

• Reduce engine wear
• Improve fuel economy
• Support smoother engine performance
• Prevent overheating
• Extend engine life
• Help maintain warranty compliance

Using the wrong oil or delaying oil changes can negatively impact performance and increase long-term repair costs.

Understanding the Main Types of Motor Oil

Different engines and driving habits may require different types of oil. Understanding how each oil type works can help drivers make more informed maintenance decisions.

What is Conventional Motor Oil?

Conventional motor oil is refined crude oil designed for standard engine lubrication and protection.

Best Uses for Conventional Motor Oil

Conventional oil may work well for:

• Older vehicles
• Light daily driving
• Drivers with shorter commutes
• Vehicles with basic engine designs

Benefits of Conventional Motor Oil

Conventional oil can offer:

• Lower upfront maintenance costs
• Reliable lubrication for many standard engines
• Widely available service options

Drivers using conventional oil may need more frequent oil changes than those using synthetic oil.

What is Full Synthetic Engine Oil?

Full synthetic engine oil is chemically engineered for improved performance, temperature resistance, and engine protection.

Best Uses for Full Synthetic Engine Oil

Synthetic oil is commonly recommended for:

• Turbocharged engines
• High-performance vehicles
• Extreme hot or cold temperatures
• Heavy towing conditions
• Stop-and-go traffic driving

Benefits of Full Synthetic Engine Oil

Full synthetic oil can help provide:

• Improved cold-weather protection
• Better high-temperature stability
• Reduced sludge buildup
• Longer oil change intervals
• Improved engine cleanliness

Many modern Chevrolet, Cadillac, Buick, and GMC models require synthetic oil or GM dexos® certified oil to meet factory recommendations.

What is Synthetic Blend Oil?

Synthetic blend oil combines conventional oil with synthetic additives to provide balanced protection at an affordable price.

Best Uses for Synthetic Blend Oil

Synthetic blend oil may benefit:

• Drivers wanting added protection without full synthetic pricing
• Light towing applications
• Moderate driving conditions
• Higher-mileage daily commuters

Benefits of Synthetic Blend Oil

Synthetic blends may offer:

• Better protection than conventional oil
• Improved resistance to heat
• Reduced engine deposits
• More affordable pricing than full synthetic oil

What is High-Mileage Oil?

High-mileage oil is designed for vehicles with higher odometer readings and aging engine components.

Best Uses for High-Mileage Oil

High-mileage oil may help drivers with:

• Vehicles exceeding 75,000 miles
• Minor oil leaks
• Older engine seals
• Increased oil consumption

Benefits of High-Mileage Oil

High-mileage oil may provide:

• Seal conditioners
• Reduced engine wear
• Improved lubrication
• Better protection for aging components

Understanding Oil Viscosity Ratings

Oil viscosity ratings help drivers understand how oil performs in different temperatures.

What Does 0W-20 or 5W-30 Mean?

The first number represents how the oil flows in cold temperatures. The “W” stands for Winter. The second number represents the oil thickness at normal operating temperatures.

Examples include:

• 0W-20 for improved cold-weather flow and fuel efficiency
• 5W-30 for balanced protection in many climates
• 10W-40 for thicker protection in higher-temperature conditions

Why Oil Viscosity Matters

Using the correct viscosity helps:

• Maintain proper engine lubrication
• Improve cold-start performance
• Reduce unnecessary engine strain
• Support fuel efficiency
• Protect internal components

Always follow the oil viscosity listed in your owner’s manual or recommended by the manufacturer.

Why Manufacturer Oil Certifications Matter

Many automakers require specific oil certifications to help protect modern engine systems.

Understanding API and ILSAC Standards

API certifications and ILSAC standards help confirm that engine oil meets modern performance and protection requirements.

Certified oils are tested for:

• Engine cleanliness
• Wear protection
• Fuel economy performance
• Emissions system compatibility
• Temperature stability

Understanding GM dexos® Oil Requirements

Many GM vehicles require dexos® approved oil to help protect engine components and maintain proper engine performance.

Using non-approved oil in vehicles requiring dexos® certification may:

• Reduce engine protection
• Impact on fuel economy
• Increase engine deposits
• Potentially affects warranty coverage

The service team at Tom Clark Auto Park can help drivers identify the proper oil specifications for their vehicle.

What Happens If You Skip Oil Changes?

Routine oil changes are one of the most important maintenance services for long-term engine health.

Engine Sludge Can Build Up Quickly

Old or contaminated oil may begin forming sludge deposits inside the engine.

Sludge buildup can lead to:

• Reduced lubrication
• Restricted oil flow
• Increased engine temperatures
• Premature component wear

Dirty oil increases friction inside the engine, forcing components to work harder and potentially reducing fuel efficiency.

Using the Wrong Oil Can Increase Engine Wear

Oil that does not meet manufacturer requirements may fail to properly protect critical engine components.

This may increase the risk of:

• Excessive wear
• Engine overheating
• Internal damage
• Expensive repair costs

Use an Oil Selector Tool to Find the Right Oil

Drivers unsure which oil their vehicle needs can use an OEM-approved oil compatibility tool or a manufacturer's oil finder.

Benefits of Using an Oil Finder Tool

Oil selector tools help drivers:

• Identify proper viscosity ratings
• Find approved oil certifications
• Confirm synthetic oil requirements
• Match oil to specific engine types

The service department at Tom Clark Auto Park can also help verify the correct oil for your vehicle during your next service visit.
