The Best Synthetic High Mileage Oil

25,000 Mile Oil Change
Generally speaking, synthetic motor oil will nearly always last longer than conventional oil, saving you time and money. But your specific synthetic oil change interval will depend on several factors, including operating conditions, motor oil quality and personal preference.

Like any other product, quality plays a big role, and in the case of motor oil helps determine service life and effectiveness. Synthetic motor oil is formulated using higher-quality raw materials than conventional oil, allowing it to perform better and last longer.

AMSOIL Signature Series Synthetic Motor Oil, for example, is guaranteed for 25,000 miles/700 hours of operation/one year, whichever comes first, in normal service (15,000 miles in severe service). Its synthetic base oils don’t contain the impurities inherent to conventional oils, allowing it to more effectively resist chemical breakdown and extreme heat. Signature Series is also formulated with high-quality additives that effectively neutralize contaminants for long service life.

By lasting longer than other oils, Signature Series offers the benefits of changing oil less often, saving you time and money.

The Million Mile Trucking Testimonial

After 1.6 million miles on the original drivetrain and 1.1 million on the factory‐rebuilt engine, Jerry Pruett and his AMSOIL‐lubed Kenworth show no signs of retiring.

When AMSOIL Dealer Jerry Pruett of Woodhull, Ill. purchased his new 1999 Kenworth over‐the‐road truck in December 1998, he thought it might run forever if he installed AMSOIL synthetic lubricants. Now with more than 1.6 million miles on the drivetrain and over 1.1 million on the factory‐rebuilt engine, "forever" still remains in sight.
