Question by The Wise Cat Named Binky: What is the effect of having your Oil Filter in “Bypass” for 4000 miles on Synthetic Oil?
1991 Olds Calais 2.5L “Iron Duke” Tech4
Valvoline MaxLife FUL LSYNTHETIC 5W-30 Motor Oil, looking for First Oil Change interval of 4000 Miles
Filter probably Sludged.. will it be Ok in Bypass?
ATF nad SeaFoam is out of engine, its all MaxLife FS in there now…
Then thinking of 6000 or 7000 mile oil Change Interval after this 1st 4000 mile Interval with possible “Bypassed” Filter? The oil and engine will be fine, yes or No?
How Incredibly Important?
Michael: I heard there was a “Bypass Valve” that opens if the filter is “Clogged.” I think Mine got clogged from the Transmisison Fluid.

What do you mean “bypass”?
Bottom line….change the oil filter EVERY time you change your oil. It’s only $ 2-4 and is incredibly important for your engine.
