I too am in the midst of an oil consumption problem. I'm using about a quart every 500 miles. My VX is still under factory warranty so I'm having an oil consumption test being done by the dealer. I was already approved for a new motor when the service mgr. skipped with my paperwork (Go Isuzu site member). I don't much care for the new dealership that is doing the test now but if it gets me a new motor I'll put up with their rudeness. But just be sure to keep on top of checking your oil because if you're not under warranty you'll be buying a new one yourself!
