Hey all, just got an E36 M3 and was wondering what viscosity you all recommend for the s52 engine? Currently I am running the Motul x-cess 8100 5w40 and this is what I use in my carrera 4s and is a great oil, track or street, IMO. I performed the first oil change and used the Motul and now have a slight lower end tick. I was thinking about going to a 10w50+, anyone running higher than a 5w40 in their s52 engine? Thanks!!
