When should a consumer switch their vehicle over to high mileage oil and what are the benefits?
There is no set mileage at which you should say a vehicle is a “high mileage” vehicle. If you are having to add motor oil to the crankcase between oil changes due to leakage, the vehicle is a good candidate for O’Reilly brand High Mileage Motor Oil. The High Mileage Motor Oil will help condition the seals in the motor to prevent leaks.
