I've always wondered how this would go. What is better, 3000 miles dino oil regular 1995 filter or what I just tried- 6500 miles+ with synthetic 15w40, LF3974 Fleetguard stratapore filter [25$] and a Baldwin B164 Bypass filter [13$] just sent my oil sample to Blackstone today so we shall find out soon enough. Worst case I keep the way better filtration system and cut back on my drain intervals- I went closer to 7000 miles. Engine ran great. Oil looked awful coming out, but it looks awful brand new coming threw a bypass filter- welcome to soot filled idi's. 128k miles and new rings @ 91k. Is What it is.
