" From: "John Elle" <johnelle@xxxxxxxxx> " " Snip " The plus 40 weights are a trade off. While I agree that a 30 + oil is " great for summer time. There is a trade off. " Snip " I don't agree, i didn't either. i've always used 10w30 here, but our winters rarely get below 15f overnight and august 90s is considered hot. " it is 114 today, I been driving all day on combination " freeway and city, speed limit 75. Typical of my driving, the engine " runs measurably cooler 'specially in comparison to "factory recommended " winter grade oils for fuel mileage purposes". Been doing it for " close to 20 years on brand new and brand new rebuilds and all " other engines. I get upwards of 300,000 miles with no oil related " problems, but the biggest is, I can see the difference on the heat " gauge. " The last oil burner I owned was the last N.E. car I owned before " I moved out of the snow belt in 1978. At about 800 miles per " quart at 100,000 miles I would call it an oil burner. " Still looking for 20-W-50, I use it year around. " My engines don't use oil between oil changes. you're in one of the few areas where that makes sense. you may have to settle for CI rated diesel oil, 15w40, though... ________________________________________________________________________ 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://www.amc-list.com/mailman/listinfo/amc-list
