Isuzu bulletin confirms oil use bull****

[Gussie2000]

We've known all along that Isuzu said 1 quart in 1000 miles was acceptable. I posted that dealer oil useage report here a while back.

This new document that we're seeing for the first time says that 1 quart in 1000 miles is NOT acceptable in these other engines. They knew there was something wrong on the first gen 3.5L that we have, so they came out with the bogus 1/1000 figure so they wouldn't have to repair thousands of engines.

This is also the first time we've seen that anything over 36,000 can use any amount of oil and that won't get a warranty repair. So over 36K their engines are too old to expect normal oil useage? That should be a major embarrassment to Isuzu.

What does it matter which engine is using 1 in 1000? It's not acceptable in those newer engines and it shouldn't have been allowed to happen with our engines.

That's where I come off.

I bought my horse @ 38K miles & oil compsumtion was notorious;The previous owner did all maintainance on time (carfax certified shows all records of maintainance).
Another BS is the warranty,why a 2nd owner shouldn't enjoy the same warranty period as the original owner ?
Specially an very low mileage vehicule.
As how my mech always told me: 36K warranty for a well reputated car manufacturer such as isuzu is just shamefull & that is what many customer should look at when they were about to choose any isuzu products.
If isuzu,as they state BRUTALLY TESTED their engines to meet higher standarts & prove their quality/reliability/dependability why offers only 36K powertrain warranty / 5years ?

As my mech also said : they knew what was coming when they decide to put this 3.5L engine into production.

Yes,almost all manufacturers says that 1q of oil every 1K is normal,but it doesn't mean that right after 36K miles you engine should be burning that amount of oil,cylinder walls,O rings & pistons should be still brand-new at that mileage UNLESS there's a factory flaw in its design/manufacturing process;My brother-in-law old '95 pathfinder had 340K miles on it & never experience oil burn although nissan's bulletin disclaimed the same average oil burn is ok.
All this bulletin does is proving isuzu's misstep & now i wonder how isuzu being the japs automobile pioneer (since 1912) didn't master this kind of situation long time ago & customers had to wait 'till they built the best fuel engine up-to-date back in 2002 with the axiom D.I. system.
90 years is a long way to go for sure.

ya, i was gonna say that my integra has 250k miles and still doesnt burn a drop of oil....

Fortunately I don't have an oil use problem in my VX (knock on wood).
But, I find it hard to believe that any auto manufacturer would find it "acceptable" for a vehicle to not make it between oil changes without having to top off 3/4 of its oil capacity.

I think IF my VX ever dies a full 'yota drivetrain might just slip in there nicely. And no worry about finding parts!

[pbkid]

BTW, I've never hated Isuzu at any time. I love my VX and my engine.

If I was one of those who lost an engine after losing a damaging amount of oil in just 2000-3000 miles, then I'd be boiling mad.
ya, it does kinda suck....

that was always my plan for my VX ultimately. especially because you could easily get SAS parts for toyota stuff....

You might be able to throw some nice FJ cruiser parts in there............................................. ................... That was for Zeus

I wish my V only drank 1qt. in 1K mi. I check every fill up, about 270 - 300 Miles, and I have to add each time. I'll empty a 5qt. container of 5W30 Full Synthetic every 3000 miles.

[TheGanzman]

I always feel sheepish when I mention that my 61K mile 2001 VX uses ZERO oil between 5K (synthetic) oil changes - kinda makes me feel "guilty" that I'm not having this problem!

Big Swede, I hope you don't mind me quoting your post from another oil consumption-related thread:

"Sometime in 2000 IIRC Isuzu changed the piston oil ring design to include additional drain holes. This was the primary culprit, although clogged EGRs seem to be a contributing problem too, near as I can determine.

The updated design can be identified by a screw-in PCV valve, as opposed to a push-in design earlier..."

This got me curious, so I went out and checked mine. Unless it was changed, mine is (still) a push-in PCV valve (it's an Isuzu P/N/# too), for the record...

I was thinking about parts from a Saturn, I am a glutton for vehicle manufacturers that no longer exist... Maybe some nice Daewoo axles?
