Oil filter debates are silly because the differences only start coming into play when the oils been on for too long anyway!
Just saw how much oil I used to use lol, fixed some leaks and would use less than half that now with 5w-30. I'm a bit scared of Nulon because they're so new, Penrite racing 10 sounds good because they're a Class IV synthetic and share the same ingredients as more expensive oils.
I've used Nulon Fully synthetic, penrite synth, penrite racing 10 and edge and they all seem to burn about the same, Been most happy with penrite racing and edge so far (cold starts sound smoother, oil goes darker later and the car is overall smoother all the way to service intervals)
What do you guys think about using 5w-30 on a 180k Healthy H22? Cold starts sound nicer and the car overall drives better but I'm starting to think its a bit thin for its age, hopefully oil consumption will improve somewhat when I fix my final oil seep.
