I have an 02 WRX with 70k miles on it, i was wondering what kind of oil i should go with. Synthetic or not? I have been told that the normal oil is now 50 percent sythetic so it doesnt really matter. And if i were to go with synthetic, what are the benefits?
Also I found that this hose has a crack on the bottom where it meets the pipe, it seems like it still works but its not very snug and might be leaking, i wiped off some brownish blackish crap before i took the pic. Im wondering what the hose and pipe do, and if i should immediately get it fixed..
