and have added 1 qt since w/9500 on now. I mentioned this to local dealer and he had vague,non-commital response. I do almost zero "stop/go" driving and most is hauling ass on two lanes or freeways. Hard to know. '01 3.0 Sport,5 Spd. Fwiw, my guess is the 5 Spd manuals see more freguent higher revs than the autos,esp w/the stump puller 1s and tight 2nd gear ratio, and no O/D in 5th. BR,md
