i just had my first oil change...i wasn't able to do it at 500 miles like random suggested...but i got it done at 721 today...pennzoil 10w40...i figger i'll do that until it hits 6000, when i'll go completely synthetic. i used full synth in my old probe when it had over 200k miles...it prolly saved that car...or had a part in that. <img src=icon_smile_big.gif border=0 align=middle>
