There are other more positive advatages of using a quality bypass filter.
1) By reducing the size of abrasive particles in the oil wear is reduced. Even oil that is changed every 3000 mile will have particles in excess of 15 microns in it that will wear on bearings, cylinder walls, rings, cam, etc. The smaller particles left in the oil (usually 1 micron or less) actually polish these parts like the difference between rubbing compound and very fine polishing compound.
2) Viscosity increase as the oil "ages". Viscosity is the ability of oil to stick to parts. Anyone who has a bypass filter and more than 50,000 miles on there oil (as long as there oil tests fine) can check this out by removing their dipstick and the oil will not drip off of it.
3) Reduced soot in the oil. With the advent of ULSD the ability of the oil to hold soot in suspension in has changed. The new specifications for diesel oil bear this out. The bypass filter removes most soot from the oil.
4) Sludge build up is eliminated. No matter how often you change your oil sludge will slowly build up in the pan. Bypass filters (some) help neutrilize acid build up.
We have used bypass filters in our Dump trucks for millions of miles. We see a large savings in oil, oil filters and the most savings in maintenance. We had one engine (a Ford Cummins 8. 3 Brazilian motor) that went over a million miles without any overhaul and it still uses no oil today. I am not affiliated with this company in any way
