2000 Isuzu Trooper: excessive oil consumption

Filed Apr 20, 2009 · Engine · 103,000 miles · PA

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.

I puchased my 2000 isuzu trooper in february 2004 with 36,000 miles on the engine. Since then I have changed my own oil every 3,000 miles religiously. I have either changed at my work (a local chevrolet dealership) or at my own home.*ak the last time I changed my oil was 2 months ago (9/25/04) at 47900 miles and on (11/24/04) with 49800 miles the oil light flashed at me when I came to a stop about a block from my home then went out. Once I got home I checked the oil and it did not register on the dipstick at all. I started to pour in oil it took all of 4 quarts of oil to fill it full. This is an on going problem with my vehicle being I have been trying to keep record of it as I was advised by a repair shop months ago when I first noticed the problem with this vehicle shortly after I purchased it. I believe by now I am over the 60 month warranty per isuzu but I will check on that (11/26/04), but I also have an extended warranty through heritage that I purchased with the trooper. I am probably one of the few that may get this taken care of on someone else's dime. But I personally know that this is a known problem by the manufacturer and there are many people out there with this same type of vehicle with this problem as I have seen on the internet. All you have to do is type "oil consumption 2000 isuzu trooper" and have fun, it will keep you busy all day. I believe the manufacture should do something about this problem.

I have been adding 1-2 quarts of oil every 5,000 miles. Dealership says they cannot find problem. Check engine light came on and they say that the problem is the valve which is not covered under powertrain warranty costing me $470. And they still don't know why I had to add two quarts over the last 2500 miles.
