PetroSavers for Buses

Normal oil and filter changes for school buses range from 3,000 miles on gasoline engines and 6,000 miles on diesel engines.

Because of the individual PetroSavers Engine Oil Refiner System's approach to each engine’s crankcase capacity, the oil in each engine is completely refined a minimum of seven (7) times per hour, regardless of the amount of oil that is in the crankcase.

All PetroSavers Engine Oil Refiner Pac Elements and engine oil filters will last 30,000 miles (48,000 kilometers) or 2,000 engine hours before needing to be changed, versus 3,000 miles for gasoline engines and 6,000 miles or 250 engine hours for diesel engines.

To date, more than 150 school buses have successfully accumulated more than 5 million miles without an oil change with the use of the PetroSavers Engine Oil Refiner System.

This includes six different makers, eight different types of diesel engines, and three types of gasoline engines.
