" From: Joe Smith <know_ware@xxxxxxxxx> " " I am confused about the motor oil information. When I read about the " high ZDDP oils, they are either for diesel engines or they say to " change at 500 miles, but the other forums I have read say leave it in " for 3000 to 10000 miles!! the 500 milers are probably break-in oils. it's normal to change oil at that point on a fresh [re]build. " I have a OHV 196, so, what is best? I just changed oil also. Is " there an additive that I can put in so that I don't waste this fresh " oil? gm eos is probably the easiest solution, but you might only find it at the larger gm parts depts. btw it's been around for a while, but now it's also getting an acdelco part number. stp used to have a red bottle 4-cyl additive that was mostly zddp, but it's been taken off the market. ________________________________________________________________________ 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
