Question about 2001 Isuzu Trooper

Excessive Oil consumption, 2001 Isuzu Trooper, V-6, 94,000 miles

Have owned this SUV since it had 6000 on the clock.
It has been well maintained with regular oil changes, etc.
For some time now, I've had to closely watch the oil level.
It is now going through a quart every 600 miles.
I think this is a sign of something very bad to come.
I've already had to put a trans in it, burned up at 82,000 miles.
There are absolutely no leaks, I've gone over it thoroughly.
Burning a quart every 600 miles must indicate something serious.
Do you agree? Any ideas?

    I havw owned a 2000 trooper from 90000 mi to now it has 150000 mi. The oil consumption is increaseing from 1 qt every 1500 at 90000 to 1 qt every 500 now. It should be the seal of the rings but reading the internet it may be other internal leakage to the combustion chamber. It doesnot leak oil. The other problem is on occation with a cold start it runs ruff spits and rpms vary for about 30 sec to 1 minute then runs fine for the rest of the day. This may be caused by exhaust system with too much carbon.

The Isuzu rep. says that it is normal for one to use a quart of oil every 750 to 1200 miles per. Isuzu motor co. I have worked for a dealer for over 15 years. I have seen a few of them come in with no oil in them because people never checked it. They thought they were good until the next oil change. Remember these vehicles have a 4.55 gear in the rear end and running 80 or faster on the highway it will be wound up tight.

have an accredited service shop to a wet and dry compression test on the engine
That determines engine condition
have the oil pressure checked using a mechanical gauge and if the pressure is below specs that indicates worn bearings overloading the oil control rings
leaks can be rear main seal or crank shaft seal at the front where the oil is blown away in the slip stream

I switched to the 15w40 diesel oil and my oil consumption dropped...

Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside. I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.

2001 Isuzu Trooper 3.5L DOHC Motor...................... Burns approximately a 1 quart of motor oil every 3-400 miles. 10/30 Motor Oil. Whats the problem? 2nd question: Same vehicle, Torque on Demand 4WD...

The Isuzu 3.5's all burn about 1 quart between oil changes. It was an engineering flaw with that model engine. Some people have said that running full synthetic oil will correct the problem over time. Either way, it is extremely important that you check your oil regularly.

As for you second question: Torque on demand has at its heart wheel speed sensors which typically are the issue. Having a wheel speed sensor replaced will set you back about $300.

I hope I was helpful.

My 2000 isuzu trooper seems to use oil a little, I've checked the antifreeze-nothing,spark plugs look fine, and no smoke out the back....I can't figure out were the oil goes... Any ideas I would appreciate...

How much is a little oil? 1 quart(US) in 5000 miles is reasonable oil consumption. If you don't have any major leaks, the oil is going out the exhaust pipe. As the engine wears the piston rings dont seal as well as they used too and the oil gets burned in the combustion process. You didnt mention how many miles you have on the vehicle, An engine with 150,000-175,000 is going to burn a little oil..

Yes, GENTLY break the motor in to about 1k miles after that, change the oil/filters and you will slowly see an increase in your mpg. I had the same problem with mine. Now has 60k on new motor and I get a consistent 20mpg on the hwy. City mileage is about 12.

1998 trooper 3.5 l oil consumption

Hi there and sorry to say... I have a 99 trooper with the 3.5 in it and I took it to the dealer last year to get an O2 sensor installed. While I was there, I spent alot of time with the mechanic while he was working on my trooper....asking questions and so on. Well, one of my questions was the same as you asked and his response was, "the 3.5 came out and lots of people would drive them like most will now days and just put gas in them and go and never really check the oil till it's too late and the engine locks up".

Well that kinda scared me, especially since I had only had it for about 6 months. I felt like I had been taken! .. However, he said,"the gage will read properly, good pressure and bad. However, it will not alert you to low oil pressure, like an oil light or buzzer, so you really keep a watchful eye on it, along with checking the oil on at least a weekly basis".

That was a little over 2 years ago, June 2006 with 80K miles on her. I change the oil on a consistant bases and add oil on a weekly basis. Now she has over 150K miles on her. I feel confident that there is at least another 150K stress free miles to go.

Hope this helps!
