Tighter bearing tolerances, fuel economy issues, controlling emissions at startup. My girlfriend's Xterra gets Mobil 1 5W-30 at every change. I was a bit surprised that the manual recommended that oil weight, but it's worked out fine. The Mobil 1 means that I've extended the changes out to 6k miles from the usual 3k as well. My friend's Chevy Avalanche uses 5W-30 as well, in a 350 small block. Almost 100k on that truck, and no signs that it's burning oil. -Mat -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
