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 personally run the valvoline, seems to be a tad quieter on the valvetrain.
Recently started using in my 2002 M3 and the oil runs cooler compared to the "twin power" oem oil i had been using.
Redline 10w30 full synthetic if I know I'm going to beat the piss out of it for the next 5k miles (think autocross or mountain runs), otherwise I use Honda 10w30 full synthetic.
Valvoline VR1 has zinc and they make a 20w50 for "race" application.
I do not use auto oil. Motorcycles run hotter and I don’t trust car oil. I use Red Line. They sell a V-Twin kit that has engine oil primary oil and transmission oil, and fuel system cleaner. I buy one each spring.
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
