" From: "Bruce Hevner" <scramblr@xxxxxxxxxxx> " " " What is "low Zinc" oil on the shelf? Look for the circle with the "API " Certified for gasoline engines" in it. This is a LOW ZINC oil and should " be used in roller engines only (according to the Shell Engineer). Low " Zinc oil will be approx 600- 800 or less, some MUCH less. you forgot to mention what the api cert should be! most oil today is api cert 'sm' and that's the low zinc stuff. 'si' and earlier [like the walmart 'sf'] is the high stuff. for diesel oil, 'ci' is high, 'cj' lower. ________________________________________________________________________ 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
