NHTSA Complaint #10188393 — 2000 ISUZU TROOPER

VEHICLE USES EXCESSIVE OIL. THIS IS A COMMON PROBLEM WITH THE 3.6L IN 2000. CHECK THE ISUZU FORUM ONLINE. ON HIGHWAY TRIPS, USES 1 QUART EVERY 200 MILES. ON SHORTER TRIPS IN TOWN, CAN GO 500 TO 700 MILES BEFORE NEEDING A QUART. IT DOESN'T LEAK, AND DOESN'T BURN. THE PROBLEM IS CAUSED BY THE OIL NOT DRAINING DOWN AFTER BEING PUSHED ON TOP THE CYLINDERS. IT EVENTUALLY HAS TO BE BURNED, OR SENT THROUGH THE EXHAUST, PARTICULARLY ON LONG TRIPS. ON SHORTER TRIPS, YOU STOP BEFORE TO MUCH IS BURNED OFF OR PUSHED OUT, SO IT DRAINS BACK. THE OIL DRAIN BACK HOLES ARE TO SMALL AND TO FEW. I'M TOLD THERE ARE 4, BUT ON LATER ENGINES THERE ARE 10 PER CYLINDER. ISUZU SHOULD BE MADE TO OWN UP TO THE DESIGN PROBLEM AND FIX THE ENGINES. I BOUGHT MINE AT 22,000 MILES, AND NOW HAVE 100,000, AND IT HAS ALWAYS DONE THIS, BUT GOTTEN PROGRESSIVELY WORSE. *JB
