I just changed the oil in my new targa at the 300 mile mark...now the engine does a funky little pinging noise. I have a vw beetle that wouldn't run right for a month when i changed the oil, so i stopped doing it. However, i tend to think the ped oil is more for the tranny than the engine itself, and it needs to stay fairly clean.
I guess what worries me more is now with the new biturbo, i can (and do) run up to 44 mph. I'm waiting for a ticket anyday...probly no good since i'm on probation. But, what the hell...
I'll run it til it blows, then have Ree ship me equivalent A3 parts...heehee.
