You change to their oil and filter, and when you reach 12500 miles you replace the filter and add a quart of oil, then drive another 12500 and your ready for a complete oil change. If you are using the by-pass filter along with a full-flow filter and have a oil sample checked in the lab you still change the filters and add oil put you dont change the oil untill the sample does not pass. The oil filters you are referring to is outdated filtration technology. Consider the sequence of events below: 1st) Donaldson Company Selected to Develop Filtration System for U.S. Army Abrams-Crusader Common Engine Program - Article link 2nd) Go Twice the Distance With Donaldson Endurance� Air Filters - pdf link 3rd) AMSOIL� Introduces Donaldson Endurance� Air and Oil Filters with Nanofiber Technology - Press Release link 4th) AMSOIL Ea Oil Filters (EaO) - Data link 5th) AMSOIL Ea Air Filters (EaA) - Data link CompSyn

Cummins sent out a bulletin on extended oil changes. It provided that those companies who used oil analysis could go to 30,000 miles intervals with Mobil 1. Jim

The Tri-Synthetic formula of 1990s. Mobil 1s current SuperSyn formula that was introduced in 2002 has been under a lot fire lately for higher levels of Iron found in UOA reports.

Do those trucks come with by-pass oil filters on them? Well, that is impressive - 30,000-miles on conventional oil. So how does 409,000-miles hit ya? 409,000-mile Mack E7-400 engine teardown � link Imagine the tens of thousands your company could save with that� CompSyn Last edited by CompSyn; 04/02/09 05:56 PM.
