i got SC, i still have 2 cases of 5w-20
I have heard people use 10w-30 and 10-40 after boost.
What grade you guys recommend?

 

using 5w20 synthetic

 

5w-30 Royal Purple. Why do people switch? personal preference?

 

yeah, same grade, full synthitic here (mobile1 5w-30)

 

AMZ-OIL 10-30

 

i've asked my dealership if i should switch to a heavier oil since i had the supercharger put on, and the tech said absolutely not.

so whatever you were using before, either the 5w30 or 5w20 depending on what year you are, stick with that, but i reccommend synthetic oil.

 

I like 5w30 full synthetic. We now carry and will begin to use Motul. Prior to that, it was Mobil 1

 

thanks for the reply, Now i don't have to worry about the oil being too thin.

 

stay with same 5 30 ..

 

but the 08 tC actually uses 5w 20.... wtf right... am i an idiot for using 5w 30 then? paul, chime in! what oil shoudl i be using?

 

use whatever the factory recommends. usually, if its rated 5w-20, u can use 5w-30 in the hotter months.

u do not go any higher just b/c u boost. the bearing clearances in your stock motor havent changed b/c u boost. boost does not heat up your oil or engine anymore than it does stock if ur cooling system is still functional. Yes, combustion temps may rise, but oil and coolant remain constant.

 

^^in hawaii its hot all d time! haha

 

When I was supercharged I used Mobil 1 fully synthetic 5w-30 and I still use that and now im turbo

 

haha should be good still java, i would stick with that.. you shouldnt have problems, and its always hot there
