What owners say
99 isuzu trooper 3.5 engine burns oil excessively. I am original owner and regularly serviced per owners manual. At 50k miles, engine oil light turned on 2,500 miles after oil change and was over 4 qts low. Engine now at 60k mi and burning approx. 1 qt per 600-700 miles. Seems to be common engine defect known by mechanics and owners, but isuzu unwilling to acknowledge problem. Though monitoring constantly, I am just waiting for significant engine failure.
Engine is exhibiting abnormally high oil consumption. One quart per 500 miles. Imminent engine failure if problem is not corrected.
After maintaining our 2000 isuzu trooper by the book and being fully aware of the oil consumption problem, it blew the engine at 103000. I kept very good documentation of all the repairs- and there were a lot of them, isuzu is not backing their powertrain warranty (120,000 miles)because they found a way to get away with it by saying because I didn't have actual receipts for every oil change even though I did many myself and documented dates and mileage, they are not responsible. I've done some research which was easy because its such a common problem, but didn't find much on any trooper owners satisfied or fairly treated by isuzu. The sticker price was $32,000 when I purchased it in 2000 I fully expected to get more than 103,000 out of it. If anyone has any luck with the same problem,please let me know and in the mean time im going to do as much as I can to fight this.
Excessive oil consumption-denial by isuzu to replace engine.
The trooper of 2000 has the same main problem that thousands of other owners have - excessive oil consumption. What bothers me is that manufacturer absolutely does not care about what consumers say. There is no answer, no explanations, no recalls. Well, here is my answer - I will never buy any isuzu product again, neither me, nor my friends or relatives. The whole world knows about this major isuzu trooper problem which is not comfortable and safe to the owners. But the manufacturer couldn't care less.
Like many others I have read about, my 2000 isuzu trooper with about 63,000 miles is using oil excessively. My mechanic has found no leaks. Due to the numerous similar complaints I have read about, why has isuzu not issued some kind of recall?
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.
Excessive oil consumption. 1 qt. Every 600 miles or so. 5 qts between oil changes (3000 miles!)
From the time I bought the vehicle when it was only a couple years old, every time I brought the vehicle in for an oil change, they said it was almost empty of oil. I brought it in to a dealer several times since it was under warranty. They could never find the reason for it burning oil. Every dealer said it was a common issue with the isuzu, but they could not fix it because they could not find the problem.
