My apologies if this topic has already been discussed.
I'm supercharged with the Stillen kit and I wanted to know what motor oil you guys run on your boosted VQ. Thanks in advance.

 

Rotella or Mobil 1

 

I use Rotella and add a bottle of Liqui Moly MOS 2. No problems for 30K miles!

 

I was using Mobil 1 then switched to Castrol Edge with Syntec Technology. I still use it now NA.

 

Take a look at AMS Oil heard great studs about it

 

I use German Castrol 0w-30 because it's class IV synthetic oil that can withstand a lot of heat, a lot of other "synthetic" oil for sale in US is blended class II and III garbage. This is my 3rd VQ car I run this oil in, also tried Mobil 1 European formula but I think Castrol is a little bit better.

 

I run motul 5w40 in my TT

 

Same here.

 

I'm not boosted, but am very impressed with how smooth my VQ runs on M1 0w40. Considering its the spec oil for the GTR, it would be my pick for that application

 

Same, non-boosted G37 Coupe running M1 0W40 and had a pretty good UOA from BITOG. I would run the same or Castrol Edge 0W40 for a boosted G.
