Commercial Trucks Extend Oil Change Intervals to 160,000 miles with Increased Fuel Savings of at least 1/2 mile per gallon

PetroSavers® by-pass filter oil purification system shows significant cost savings on engine oil service.

PetroSavers® unique replacement filter elements last 30,000 miles or 2,000 engine hours before needing to be replaced.  The traditional oil change for a commercial truck is normally between 10 to 15,000 miles. PetroSavers® extends oil change intervals up to 160,000 miles.

Companies save money on oil changes but the biggest benefit for commercial trucks is the decrease in down time for over the road hauls.

Police vehicles have gone 3 million miles without an oil change and saved over 1,000 oil changes

Police vehicles are one of the most likely to need PetroSavers® by-pass oil purification system due to constant idle time in various conditions as well as rigorous performance demands on their engines.

Reduction of downtime is also a big factor with Police vehicles.  The effect on the overall engine performance with PetroSavers® system allows Police Officers to be more effective in serving the public and also saves tax payer's money.
