SL55/63/65/R230 AMG: SL55 AMG Modified - Oil Recommendation for hard driving
Have a SL55 AMG, modified, will be running circa 600hp over the summer.
I know 0w40 Mobil 1 is the stock oil choice but the car gets driven very hard and will be visiting nurburg, santa pod & various circuits. It's only a weekend car but gets driven hard.
I want a slightly higher viscocity at operating temp to protect the engine due to driving style so was considering a 0w50 or 5w50, Mobil 1 make a 0w50 but it's hard to get here. I can get 5w50 Valvoline VR1 Fully Syn off the shelf for around £80.00 a gallon.
Just wanted to see if anyone is running higher viscoity oils than stock in there 55 AMG.
Let me know your thoughts, the Valvoline VR1 is run in quite a few top end cars like M5/M6 etc.
Cheers all,
Toby
You may want to look in the back of the owners/service manuals. There is a list of approved oils, as well as the operating temperatures they are recommended for. You know how and under what conditions you drive.
