Isuzu Trooper Oil consumption possible fix or at least an improvement

[Incusus]

I've only ever seen the 15w-40 for the conventional and the 5w-40 in synthetic, so I guess that is all they make. I've always been able to find it at Wal Mart - last month I got the synthetic for my bike, and it was $22 for a gallon (it used to be 18, which was a rockin' deal for synth).

There are other HD oils available - Mobil Delvac and Castrol Tection, etc., they might work, too - I know Mobil makes a synthetic Delvac, but I have never found it in a store.

ok I've been hunting for the past few weeks and talked to my (very) trusted auto parts guy and they don't make anything but the 15w40, and I just cant see running something that heavy in an Ohio winter. I'm gonna wait until spring to try rotella.

hmm... could be a 2-season thing: rotella in the summer, 5w40 synthetic in winter, and my flush every spring and fall in between. yesss... maybeeee....
