i lose almost all the oil in 3000 miles........dont see it anywhere.......not in coolant, not leaking from pan or seals and not coming out exhaust..........i heard there was oil losing problems on this year passport........any suggestions???

And if this is not already obvious enough, check your oil level constantly, or you will loose the engine. Recommended to check every fill up. I'm so paranoid now, I check mor regularly than that.

I am with ya guys, I am averaging almost a 1/2 qt per tank of gas (320-350 Miles). Check it, check it and check it again. Something so cheap and simple could cost a you a ton later one.

have you ever replaced your pcv valve

They will use oil on long, high speed hywy runs. I've never had to add more than a half to 1qt of oil to our 2002 3.2L @ about 4000 mile oil change intervals (30K mi total on it). My cousin's 2002 trooper uses very little to nothing. On the other hand, my SIL's 2003 3.2L rodeo (4x4 5spd) shows almost nothing on the dipstick just about any time I get a chance to check it for her (2+ qts low) :uhoh: . She's got about 40K miles on it & drives the snot out of it. I offer every time to change the oil for her. Have done it a couple times for her, plus cleaned her EGR & PCV, but she insists on doing maintenance where & when she wants. Whataya gonna do :shakehead . I guess my point is, Isuzu never really did straighten out the problem.
