" From: jayscore@xxxxxxxxxxxxx " " How are the detergent levels? I've always been told not to use racing oil in a daily driver because there is not enough detergent in the oil to pick up dirt and contaminants. countering that, synthetic oil has a certain natural detergency. one reason they say never to change a high-mileage engine over from mineral to synthetic - two metric buttloads of sludge and varnish will come floating out of crannies you didn't know your engine had, and clog the oil filter. and also all your seals will start leaking, because only sludge and varnish were holding them together... so goes the wisdom. i've never tried it. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
