Another engine oil thread. Castrol Edge/Pennzoil/ Liqui Moly?

ODDs are, this oil either comes in thin from the factory (Pennzoil claims viscosity is 13.3) or it thins out with use.

It does come thin. And it will thin to 30 grade. All others will too unless KV100 is in 14’s and VII is low.
But, 10.4 is bit low unless this particular batch is from get go low KV100. Don’t forget that those are typical values on PDS. There are some VOA of PPE being 12.5.
Still, Blackstone fuel dilution method is really not reliable. It is known issue.

But all this is fine. Pentosin results are the one that confuses me.

Im sending another Pentosin Sample with about 6K miles, will post if anything is different.

Motul X-cess Gen2 5w40 might be the best street oil I've used in this viscosity grade. Excellent HTHS, excellent flash point, and can be used for relatively long OCI for highly stressed engines. Hope they keep making this one for long.

It is new formulation. So it will stay in production for some time.
It is really good oil. Correlation between KV100 and HTHS is really good. Relatively low KV100 for such good HTHS, which is what one wants.
