Took my wrx into shop for 30k service. Had oil smoke coming out of hood again. Last time the dealer spent 5 hours on it and found nada. This time they Said that they found gease oozing from my right outer boot as I had suggested before. They also said that my turbo was shot and they called SOA and were told that it was because I was using Mobile 1 oil. They are replacing both items under warrenty. They also said I have to (suggested) that I go back to stock oil to maintain warrenty.In other words no Synthetic according to SOA. This sucks. My car is less than one year old.
