Engine oil VALVOLINE or PENNZOIL

I’ve gone down an oil research rabbit hole many a time. There’s been some extensive studies done and besides liqui moly, studies have shown that Valvoline extended protection has some of the best wear-prevention additives and performed among the best in lab samples pulled from used oil.

My current favorite is valvoline 5w30 full synthetic. There are oil analysis of new that show it has a high 100 C viscosity and it has a ton of really good additives.

I am tuned in WI and running Pennzoil Ultra Platinum 5w-30

Fuck Mobil 1. Get you some penzoil ultra platinum or better yet some amsoil. They’re both miles better than Mobil 1. I used to use Mobil before switching to penzoil. The difference was noticeable

I personally run the valvoline, seems to be a tad quieter on the valvetrain.

I use Full Synthetic ( Pennzoil Platinum). At 24K I really can't even tell the engine is running when I come to a stop, its just that smooth and quiet.

Pennsoil Platinum High Mileage 0W20. It seems to run best on it, at least among the wal mart oils.

I’ve used pennzoil platinum or ultra platinum on my 8th and 9th gen si. Never burns a drop in the 3.5k mile interval changes and I beat the thing like I stole it most days.

Valvoline VR1 has zinc and they make a 20w50 for "race" application.

I use valvoline 5w-30 full synthetic in my g35. Runs great
