Yeah I’ve heard of some of Lake Speed’s stuff and the Donaldson filtration videos. The correlation between smaller particles and wear makes sense in theory. I guess the part I’m still curious about is how much of that benefit actually shows up in a real engine when the oil is already being changed around 5k miles.Efficiency is for engine wear and power loss reduction . Lake Speed did video with Donaldson showing correlation. How much more engine life? I don't know. Whatever it is I'll pay $5 more per filter a couple of times a year for it. Yeah, and pre-fill the filter. With a sideways filter, prefill it, let it soak, pour out free oil, install. Unsaturated filter media is what mostly slows oil flow through a new filter.
From the UOAs I’ve done on my truck, even with a standard Mopar filter or something like a Wix XP, the insolubles and wear metals were still right in line with averages at about a 5k OCI. So it seems like the oil is already staying pretty clean at that interval.
I’m not against running the higher efficiency filters at all; if it gives someone extra peace of mind that’s great, I’ve just been wondering how much practical difference it makes when the oil is getting changed before the filter is anywhere near its limit.
