By using synthetic, am I decreasing use of crude oil? I don't know what exactly to search for in reguards to my answer, so forgive me if this is a repost.
Thanks but do Group 5 lubes fit this statement like alkalated napthenes, polyol esters, etc?quote:

If you use a less volatile oil, of course less of it will end up out the tailpipe as opposed to sitting in the crankcase where it belongs.quote:

I dont think i know how this happens..if your car doesn't burn oil...how can it produce a better emmissions report if you use Mobil 1 instead of Havoline.
