2010 SE STI


I have 2010 SE STI, Cobb Stage I + AEM. car has been using Rotella T6 5w-40 for last 35k miles. no issues.

burn about 1qt every oil change, mostly from PCV blowby.
S# can run up to 18PSI. MobileOne 5w-30 burned like no tomorrow, I had to use T6.

if your turbo run beyond stock 14.7PSI, heavier Rotella is a good idea.
