My Moms 03' subaru has went through 2 engines, as in they both just blew up. Both only had gotten like 45,000 miles before they threw a rod or blew a head or something....? Anyways the first one we thought blew up because we switched to synthetic oil because it blew up a few changes later. and the second (Brand new one mind you from subaru) just started using oil like an SOB like a quart every few weeks and it doesn't seem to be burning it and its not leaking it. its just gone. anyways that one blew. and now its at 105,000 miles or so with another used engine and its starting to tap something horrible. ONly thing I can think of is the fram filters my dad has been getting for them the entire time.... or that subaru sucks lol.
