i get no white smoke either - apparently its not burning oil it just "uses" it and from what ive read on here there is a difference - even though i dont wish for anyone to have the oil issue its oddly comforting to know someone else is in my same boat - with your axiom i think they might have fixed the problem by drilling extra holes for the oil to drain through in the pistons - they have rebuild kits that members have used (y33treker maybe?) with the new pistons and whatnot and i believe some newer 3.5ls like your axiom have a good chance to have the version with the problem fixed
Alrighty then! IMO, I think I'll not mess with it, oil's cheaper than pistons, lol. I did notice that the last time I checked at 1000 miles it was only (only, lol) a 1/2 quart lower than usual. Hallejulah, it healing itself!!
