Hey guys, first time poster and new owner of a 2011 wrx hatch back! I'll post some pics after work...
Anyway, this may seem like a dumb question.
I bought the car used at 38,000 miles and the dealship said they were un-aware of what type of oil the original owner used. My question is, if I switch to a synthetic oil like amsoil, would it cause any leakage through my gaskets? I was told that if you use a low quality oil and then switch to a synthetic, the molecule structure is much smaller and you will have oil leaking out through all your gaskets.
Is this true and should I be concerned with switching oils?
Thanks so much in advance guys!
