Engine Oil F.A.Q.

Synthetic Motor Oils: Myths vs. Facts
Looking for the real story on synthetics? Wondering what's true and what's not? These are some misconceptions about synthetics, and facts to set the record straight:
  • MYTH: Once I use synthetic motor oil in my car, I cannot switch back to conventional motor oil.
  • FACT: Synthetic motor oils are compatible with conventional and part synthetic (blend) motor oils. However, synthetics deliver superior engine protection versus conventional oils.
  • MYTH: Using synthetic motor oil will void my vehicle’s warranty.
  • FACT: Using synthetic motor oil will not void your vehicle’s warranty. Synthetics are formulated to not only meet minimum required industry standards, but also, in many cases, meet tougher industry and vehicle manufacturer standards.
  • MYTH: Synthetic oil is only for new cars.
  • FACT: Quality synthetic motor oil can be used in old as well as new cars, including vehicles in which conventional oil was previously used. Synthetic motor oils are beneficial for the good health, long life and top performance of new and old cars.
  • MYTH: You need to allow a break-in period for new vehicles before using synthetic motor oil.
  • FACT: In the past, it was recommended that conventional motor oil be used for your first oil change to allow for some controlled wear to break-in the new engine. However, with current engine technology, a break-in period is not necessary. You can use synthetics immediately.

** Guarantee excludes severe service applications such as frequent towing and hauling, racing, dirty conditions, and extreme idling. If your vehicle is covered by a warranty, follow your car manufacturer's recommended oil change/service intervals, which can be found in your owners manual.
