What is the best oil for high mileage trucks?
When it comes to maintaining high mileage trucks, the choice of engine oil can make a significant difference in the vehicle's performance and longevity. The best oil for high mileage trucks is one that can effectively lubricate the engine, reduce wear and tear, and provide enhanced protection against the challenges that come with increased mileage.
Factors to Consider When Choosing Oil for High Mileage Trucks
Several factors should be taken into account when selecting the right oil for a high mileage truck:
- Viscosity: High mileage engines often require a higher viscosity oil, such as 10W-30 or 10W-40, to provide better protection and reduce oil consumption.
- Additive Package: Oils with a robust additive package, including detergents, dispersants, and anti-wear agents, can help clean and protect the engine components, especially in high mileage vehicles.
- Compatibility: It's essential to choose an oil that is compatible with the specific make, model, and year of the truck, as well as any modifications or aftermarket parts installed.
- Synthetic vs. Conventional: Synthetic oils generally offer superior performance and protection compared to conventional oils, making them a better choice for high mileage trucks.
By considering these factors, you can select the best oil for your high mileage truck, ensuring optimal engine performance and longevity.
Top Recommended Oils for High Mileage Trucks
Based on the criteria mentioned above, here are some of the top recommended oils for high mileage trucks:
- Mobil 1 High Mileage 10W-30: A synthetic blend oil that provides enhanced protection and performance for high mileage engines.
- Castrol GTX High Mileage 10W-30: A conventional oil with a specialized additive package designed to reduce oil consumption and protect against wear in high mileage engines.
- Valvoline MaxLife 10W-30: A premium conventional oil with a blend of high-quality base oils and advanced additives to help extend the life of high mileage engines.
- Pennzoil High Mileage 10W-30: A synthetic blend oil that helps reduce oil consumption and provides enhanced protection for older, high mileage engines.
Remember, it's always best to consult your truck's owner's manual or a trusted mechanic to determine the recommended oil type and viscosity for your specific vehicle.
Is 5W30 or 10W30 better for high mileage?
Using a Higher Oil Viscosity in High-Mileage Cars
An engine's life began to deteriorate rather rapidly around 100,000 miles, and so to increase the oil pressure, high-mileage car owners would use a higher oil viscosity such as 10w40 or 20w50.
What happens if I put 10W30 instead of 5W30?
Using 10W-30 instead of 5W-30, however, could make cold starts more difficult. It's helpful to think of the “W” as standing for “winter.” The lower the oil's “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30.

Is fully synthetic oil bad for old engines?
Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics. The idea that synthetic oil could harm old engines probably comes from a time before synthetic oils had been extensively tested.
What is the best oil for long distance driving?
High-quality synthetic oil with a lower viscosity, such as 5W-20 or 5W-30, is usually recommended for highway driving. These oils provide better protection, especially at high engine temperatures. They also offer improved fuel efficiency and extended oil change intervals, making them ideal for highway driving.
Is synthetic oil better for high mileage trucks?
For high mileage engines, a high mileage synthetic oil is often the best choice. Choose the viscosity based on manufacturer recommendations, and consider your engine's specific needs. If there are persistent issues like leaks or excessive consumption, consulting a mechanic may be advisable.
Should I put thicker oil in my high mileage truck?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil -- 10W -- can help protect worn engine bearings as well.

Is thicker oil better for long trips?
Not only that, but the engine will waste energy pumping the thicker oil, reducing fuel economy. Since thicker oil doesn't transfer heat as well as thinner oil, operating temperatures will increase, possibly leading to accelerated chemical break down (called “oxidation“) and harmful sludge and deposits.
