Engine oil RED LINE or MOTUL

I’m in MD and use Motul 5w30 X-clean EFE

I started using motul 10w40 after my apache rtr 180 crossed 50k kms. It gave the old engine required smoothness and the engine feels stress free.

I run X-Cess 5w-40, seems great. Takes a little longer to heat up than 5w-30 but I imagine you’d want the high thermal stability it offers in your location.

Recently started using in my 2002 M3 and the oil runs cooler compared to the "twin power" oem oil i had been using.

Motul has been phenomenal for me

Only used Motul 300V 5w30 or 5w40 since I bought the car new in 2009. Today I'm on 178k kilometers and still on the first chain and chain tensioner. No rattle, no oil consumption or what so ever.

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.

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 Motul the best IMHO

I tried the redline 5w30 previously which has very high levels of moly (>800ppm) and the results were not as good as the moly-less 5w40.
