Engine oil Mobil or LIQUI MOLY

My 02 Avalanche has has mobile 1 full synthetic it's entire life, and has 750k miles on the original engine. Never been opened or rebuilt. Piston slaps like a diesel on start up, but still running great.

Mobil1 0w-40 Full Synthetic

I use LiquiMoly TopTec 4600. Meets the BMW LL-04 spec for diesels.

I live in FL use liqui moly molygen 5w40 I’m stage 2 and 0 issues

I'm stage 3+ on e70. I was using 0w30 top tec liqui moly until stage 3 when I switched to 5w40 top tec.

I've used liqui moly top-tec 4200 5/30 on mine for the past few years, no problems.

I use mobil 1 on my 2007 k24 I\u2019ve been the only owner

I'll stick to Honda coolant, mtf, and power steering fluid but oil I go with Mobil 1.

So recently I’ve noticed that on startup I get a little white smoke that dies down after warming up to about 170 oil temp I noticed this after I changed the oil I used the same green liquimoly oil my gti has been stage 2 tuned for abt 5k miles now, stock is20 and it’s a mk7 tuned it at 100k miles I’m thinking pcv. my peak boost has gone down one psi and I remember it used to hold 28.5 right before I up shifted now it’s only 26.5

So I used Mobil 1 Euro FS 0w-40 in a 2025 Nissan Armada Pro-4x that has a 3.5L V6 twin turbo engine. I ran it for 2,000 miles and then sent in a used oil sample for analysis. I was surprised that highly touted Euro oil with all its various manufacturers spec had sheared outnof grade to a thinner 30 weight oil in only 2,000 miles.
