At least with the 1998, be prepared for oil usage....our 1998
(purchased new) used a quart of oil every 1200-1500 miles.
It slowed considerably when I put in 15W40, but prior to that, oil
usage was higher than any other car I have ever owned.

They have some quirky electrical problems with the 4wd Torque on Demand
system (usually the solenoid on the front axel) but otherwise it is a
solid well built vehicle. As far as oil usage, it has been hit and
miss... my '93 used it a lot, my '99 I don't have to add between oil
In the 3.2 and 3.5 engines Isuzu used short skirt pistons. This allowed
for reduced friction and thus increased power but also increased oil
consumption. My 1999 Amigo 3.2L uses about 1qt/3000 miles. I have 50K
on it now. No problems at all. Very dependable.
We've got two - a 1998 Luxury and a 1999 Luxury Trooper. Isuzu used the term
"Luxury" instead of Limited those years. The Luxury is exactly like the LImited
and included leather seats, roof console, sunroof, folding mirrors, fog lights,
wood trim, electric seats, heated seats, etc.
The 1998 with 98k miles was a purchase we made 3 weeks ago - paid $6,250 - green
with grey leather interior.
The 1999 with 65k miles I purchased new - paid $28k - red with grey leather
Let me say, the Isuzu Trooper is a great vehicle and unless you have unusual
tastes, you will likely think so too.
My 1999 Trooper does not use oil - I've heard that some do. I once owned a 1989
Trooper, the old style, that did use a quart between oil changes. It was only a
minor annoyance of having to put in a quart every now and then but I found that
these oil change places 'warantee' oil changes and during the oil change period
you can just drive up and ask them to check for oil fill and they will put in
more oil free.
Here is a spreadsheet of all the expenses I have in the first 65,000 miles with
my 1999 Trooper:
My advise - if you can get a good price on that Limited Trooper and it is in
good shape, buy it.
Why bother if the motor is running well on 10W-30?
Isuzu says (on mine, a diesel) 5W-30 or 10W-30 so it could be the right
one for yours too. Turbo diesels with the so-called 'common rail'
technology are apparently more sensitive to oil viscosity.
Turbo diesel !! They are not available in the USA. I've noted that they are
available in other parts of the world and think that they would have sold very
well here in the USA. Where do you live?
I also wonder why they never took off in the USA. The gas lobby? Air
pollution laws? I reckon fuel prices are still too low, at $5 a gallon
Americans will finally begin to see diesel in a new light. :-/
I'm located in Austria, USE
The Isuzu motors use oil, thats normal, don't worry about. You'll have to check
it every 1000mi or so, if it gets a quart down, put a quart in. Make sure you
change it when you're supposed to.
