Subject: Re: Amsoil vs Royal Purple vs Valvoline by Ultraman on 2010/2/14 20:51:55 Most of the new car recommended oil change intervals are at 7500 miles. On my 90 it recomends every 7500. I change my oil when the sensor says 50% oil life remaining on my Chevy trucks. That is about 5000 miles per oil change. I use Mobil Delvac in the Duramax's and M1 in the SUV's. Costs a little more but it is worth it in the long run. I think it makes a difference what kind of miles are being put on. So much of what we do is highway miles going all over to ball games or shopping. Not much stop and go city stuff. Or is miles miles no matter what? |
