Kirkland and those types of oils really struggle in severe service/extended service. As mentioned luckily that engine typically is easy on oil and did well.

ESP 0W-30. Still the GTL/PAO/Ester formula.

The tolerances are to tight in the electric oil pump for US warranty purposes.

Less valvetrain noise for sure. I didn’t even keep 0W-20 in long enough to check fuel economy. 😂

I’ve used both versions with absolutely no problems. Both looked great in my C&P’s.

Very nice!

Great experiment!! I’m also running 0W-30 in my Jeep Wrangler 3.6 and Subaru’s. All much happier.

9 months 4k miles.

Let us know what you think vs the M1 EP.

Yes. PGI made filters and Pentius filters have the most consistent quality currently. Very very rarely do I see problems.

True. I should have worded it as “I’ve seen metal shavings from thread cutting on many different filters over the years.”

Surface rust on unpainted crimp is a non issue. Metal shavings would be from the threads. Inspection before installation is a must on every brand.

Recently they changed from M+H made with all kinds of problems, to Highline Warren acting as a middle man from factories in Vietnam and S Korea. Very similar to PGI and Pentius filters.

A couple years now.

I wasn’t the one that called. But I did see the old M+H version in the gold boxes.

Pics of engine internals will please the arbitrators over all else. Only the scummiest of scumbag dealers would try to blame the oil with spotless internals. Arbitrators won’t fall for it.

Highline Warren says 99%@20 by phone. Waiting for boxes to update. Still the old M+H numbers currently.

As you know from many UOA’s posted here it’s not uncommon to drop a grade. So a car that specs a 20 grade could come back showing a 16 grade. A much bigger concern than going up a grade or two. Having worked at a dealer for 12 years UOA’s were used to find contaminants like glycol. A VOA is the...

It’s going to be a couple years to know for sure. It took 60k miles to develop the oil consumption, I’m 10k miles in with ESP. Currently consumption is continuing to improve. Down to 1/2 qt in 5k miles.
