Hey thanks again
I am swapping to 0w20 last saturday. Car seems very light and engine is not fluttering at idle.
I will try to drive the car everyday to see that i still have a leak or not.
Yeah i might be changing again over 5w30 once the supercharger installed.
I have several option here..
Ams signature 5w30
Motys m100 5w30
I would prefer ams.. what you guys thinking
