Low (and now ultralow) sulfer diesel fuel has made that much less a problem than in the past. Also the oil will neutralize a certain amount of acid. The new oils actually have less ability to do this as it isn't much needed with ULSD. Idling does use up the additives in the oil faster and loads it with soot.

egr... and now for '07, 30% more egr is what raises the level of crankcase acids...... why do you think the oil changed in '02..... and again in '07? from api-ch to ci and now to cj. the lube oil spec with the least (if any) change was cat's as they did not use egr
