Thomas G. Warner, When an engine is run,as the New York cab fleets
are,the engine oil NEVER cools down! This does not ALLOW codensation to
form,thus no acidic formation and No Coagulation of the molecules in the
oil.All of these reaction will kill an engine over time.Our engines, if
maintained,are mostly in the 100k range.The reason is most if not all of us
don't drive them 4 to 6 miles to the store for a gallon of milk! We startem
up and drive to Casa De Fruta . OBW,the cab fleet I was
talking to did not use oil filters,none,nada.When a unit was in for service
they dropped the pan,cleaned same,visually inspected the bottom end,put a
new gasket on and reinstalled!! At least thats what was going on in the mid
70's, Jim Penrod Hangin out and bein cool in Lake Placid F L

Jim its not necessarily the temp of the engine oil that is critical to long
life for an engine. Sure stopping and letting an engine cool down after
running a short distance does cause acids to form. However the constant
stop and go, quick acceleration of the cabs etc is what makes it so tough on
their engines. Its the change in stress levels on the cranks, rods and cam
that do it. Engines that run at constant speeds like those used on
irrigation pumps run a very long time. The really long life engines never
have their oil completely changed. They analyze it and add additives as
necessary.

Anyone that would run a modern engine without an oil filter is just plain
stupid. It is to high a risk.
