"agree- but your particular engine would have cratered if you didn't check yours. All I'm saying is, if you know your 3.2/3.5 uses *some* oil, you better check it often, especially on long/fast/hot hywy trips."
Point Taken. And thanks for the reply. I've been monitoring my truck since laste week, but will be travelling about 650 miles in a couple of weeks - weekend trip - and that'll be the acid test.
I'll let you guys know the outcome. Meanwhile, I think I'll call the Isuzu folks and try to get some consideration, but I don't have a high confidence level about that. (boy, I REALLY don't want to have to buy another truck.....)
Take care - be safe.
