Frequently Asked Questions

What viscosity oil should I use for my pickup truck?

Always follow the manufacturer’s recommendation found in your owner’s manual. Common viscosities for modern gasoline pickups are 5W-20, 5W-30, or 0W-20. Diesel trucks often use 15W-40 or 5W-40. Using the wrong viscosity can reduce fuel economy and engine life. We recommend checking your owner’s manual before purchasing.

Can I use diesel oil in a gasoline pickup truck?

It is not recommended. Diesel oils contain higher levels of additives like zinc and phosphorus that can harm catalytic converters in gasoline engines. They also have different viscosity and detergency profiles. Always use oil that meets the API rating specified for your engine (e.g., API SP for gasoline, API CK-4 for diesel).

How often should I change the oil in my pickup truck?

Oil change intervals vary by vehicle and driving conditions. Many modern trucks with full synthetic oil can go 7,500 to 10,000 miles between changes under normal driving. However, severe conditions like frequent towing, off-roading, or extreme temperatures may require more frequent changes, often every 5,000 miles. Always refer to your owner’s manual and consider using oil analysis for optimal intervals.

What is the difference between conventional and synthetic oil for trucks?

Synthetic oil is chemically engineered to provide better performance at extreme temperatures, greater resistance to breakdown, and improved engine cleanliness. It also allows for longer drain intervals. Conventional oil is refined from crude oil and is less expensive but offers less protection and requires more frequent changes. For modern turbocharged trucks, synthetic is often recommended.

Does using a higher quality oil improve fuel economy?

Yes, especially if you switch from a conventional to a synthetic oil with lower viscosity. Full synthetics reduce internal engine friction, which can improve fuel economy by 1-3% in some cases. However, the effect is modest and depends on driving habits and engine condition. Always use the viscosity recommended by the manufacturer for best results.
