Since I bought my car at 97K, I've used Mobil 1 every 3K or so. When I took my car in to get the HG and TB replaced, I noticed on the reciept that they changed my oil and I'm willing to bet that they didn't use synthetic. Should I change my oil back to synthetic right away or is it ok to leave it conventional for one cycle? Thanks guys.

>it'll be fine man dont be so paranoid
haha I can't help it this car drives beautifully since I got the HG done. I guess I was losing more compression then I thought. Time to go to the track
