Engine oil VALVOLINE or Lucas
I use Valvoline Synpower
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.
Right now I have some Lucas High Performance, but the brand is relatively immaterial to me. As long as it's a reputable brand and it meets the spec in the manual.
I personally run the valvoline, seems to be a tad quieter on the valvetrain.
Valvoline VR1 has zinc and they make a 20w50 for "race" application.
I use valvoline 5w-30 full synthetic in my g35. Runs great
Valvoline 20w-50 works great
I use Valvoline Extended Protection, it's really good stuff
Valvoline VR1 for the track car. Valvoline VR-1 is a very highly reviewed oil with a high zinc content to keep race engines running with very minimal wear.
