Thinks guys. I've been worried that I would not be able to change back because I read on another site that you can't. I guess I'll put it in today or tomarrow and see how it goes. Last 200 or so miles I've been cleaning it out with Seafoam and got good results.
I'm a newbi and have a question about Mobil 1. I was thinking of switching to it and would like to know if in the case I didn't like it if I could switch to a mixed oil. Or should I try a mix or blend I think it's called. My chevy has 117,000 miles and no leeks, good and clean internals.
