when did ISUZU change the engine design so that there are 10 oil drain holes instead of just 4? That is a good explanation for why newer models may not consume as much oil, and why the SeaFoam seems to be making a difference for sharktrooper. Where do you get the SeaFoam additive? My 99' Trooper seems to be consuming about 1 qt. every 2000 miles also. I just got back from a 3000+ mile trip and it used about a qt. and a half. Got reasonable mileage, about 18 mpg average at 70 mph on interstate. The mountains of N.C. were beautiful, and the Blue Ridge Parkway is quite a beautiful drive on the southern end. Great drive between Boone and Ashville. Trooper performed very well and I remembered why I bought it in the first place, great seating position and reasonable ride comfort.

I miss it. Even though the Armada has a way better ride and handling and is huge compared, there is something about the trooper that gives it a solid feel. I think I'll buy it back from my dad in about 50k miles and make it an offroader!

I think J. Lemmond posted...you should know there...He is old isuzu tech. You have to look at your PCV valve. If you have screw in type but not push in, you have new design piston/oil ring(10 hole).

Auto zone sells Sea Foam, as well as lots of other stuff. Is there an oil additive expert who can advise per this oil consumption problem?
I'm not totally sold on Sea Foam, but it comes strongly recommended for clearing engine oil carbon. Thought I'd try it for a while, measure results, and then do the next thing on the list. I'd like to understand what the problem is through working solutions in steps. Sea Foam seems to have helped some, but 800 mi/qt is still unsatisfactory, and it's worse with highway (hi rpm) driving--no real surprise here. I know there's more folks with this problem, I see sooty tail pipes in lots of newer Troopers. So come on, let's see some chatter...

Have an 02 4wd "S" with about 27000. up to 2000 miles I used about 1 qt. 1000 miles. after that, I use 1 qt. every 6000 miles with Mobil one oil. I am also running a Alpine Supercharger.... Great power addition.. Many drivers have told me about 3.5 engine oil problems... I guess I got lucky and don't have any oil problems? Trooper has been the best buy for me.. Only vehicle I have owned that, I consider better, is Toyota. Resale value seems to be on the low side but, I don;t plan to sell! Replaced OVM tires with Dueler REVO A/T 265-70-16, what a great tire... improved ride and reduced rear tire-smoking (when supercharger is working) and slipping in the rain.

Both of my '99 Troopers were using about 1 quart every 500 miles. I've tried Sea Foam and a few other additives in both the oil and gas and checked the PVC system with no improvement. Then I tried CD2 Oil detergent and my oil consumption improved to 1 quart per 1500 miles within 3000 miles from the time I added it and is still improving. I found it at WalMart and it was less than $3 a bottle. This stuff really works and I highly recommend anyone with oil consumption problems in their Trooper try this first.

I have about 54K miles on my 99 Trooper. I use Mobil One and use about 1 quart every 5K miles. When I first got it, it used about 1 quart every 3K miles.

Did you ever find the problem with this. My trooper (2000) is also doing this. But sometimes I can hit a bump in the road and it will come on. Thanks,

How long do you leave the CD2 product in the engine? Do you just put it in there for a few minutes prior to engine oil replacement and use it as a flush? Or is it an additive that stays in for the life of the new oil change?
Are you currently using Mobil 1 or a standard dino oil?
I like the sound of the oil consumption reduction you seem to have gotten with it. i think I'll give it a try as well. I'm running Mobil 1 and have in my 99' since I got it. It now has 79000+ miles on it, and runs very well; very dependable transportation. Very solid feel and no rattles or squeeks except for the rear door jiggling some times.

It's an oil additive that's added every 2000 miles according to the directions. I ran it for 2000 miles and changed the oil. I'm about 1500 miles into the second bottle now and plan on doing another oil change at 2000 miles, then just run my regular oil thereafter and use the CD2 every 4th or 5th oil change to keep it cleaned out. Major improvement by the end of the first bottle and still getting better on the second bottle. Right now after 3500 miles of CD2 I'm using 1 qt per 1500 miles. Here's a product description:
"CD-2 Oil Detergent frees sticky lifters, valves, and rings to quiet noisy engines. Dissolves sludge, carbon, and gum to extend engine life. Cleans all internal engine parts for more pep and power. Protects critical engine parts during high speed or stop and go driving."
Like I said in my previous post, I tried everything and CD2 is the only one that loosened up the sludge to free up the oil holes that are clogging.
