Regular oil changes and well maintianed until i was in coldlake and got the oil change there before heading back to edmonton. My jeep stalled on me while driving, looked under, checked everything to why it quit. Then i checked my oil, there was no damn oil in it. No leaks nothing.. i added oil, it started up again and was quite until the engine warmed up amd made a squealing sound. Could be the bearings/camshaft. I upgraded the suspension, braking, drivetrain (differentials) transfer case.etc.. everything until the oil change in coldlake..
