07 Colorado OCI

I will add one thing to this, I know car dealerships are out to get your $ but they recommend 7500 for a max oci. Which I think is quite reasonable, Also, the OLM in my colorado is rumored to be isuzu derived, not GM, It doesnt show a % just a dummy light. So I think for my application the OLM doesnt cut it, I will UOA and go from there im sure blackstone wont recommend me extending out to 15k on dino in all seriousness.

You may be in for an surprize. What does it matter that the engine was derived from Isuzu. That means it is even easier on oil.

Do an internet search for GM Atlas/Vortec series engines. They have nothing to do with Isuzu, nor do the electronics.

The OLM or your credibility?



my credibility is top notch. i dont make outlandish claims. i base my input on facts. not brand brand loyalty or marketing hype(I.E. im not a fanboy).

even in this very thread we have more reports of this not indicating a correct OCI than ones that are correct. anybody can come up with a report or two that says the oil was OK at XXXXX when the monitor went off. for me to trust the OLM it would need to be correct 90%+ of the time beacuse my hard earnd dollars are on the line, not far less than 50%. IMHO its a tool use by the auto industry to get the engine to make it thru warrenty and still wear out faster so they can sell more cars/service.

dont make me [censored] slap somebody because it will be a beatdown.

It is a different system than what GM normally uses. It is Isuzu-delivered. Mine goes off every 12K in my Colorado. But the first one went off at 13.6K. I would disregard the OLM - even if it was the more popular/more complex GM version. I recommend the old-fashioned odometer reading oil change method. Electronics go haywire when you least expect it. You may think the reading is true -- but it may not be.

If you want to risk that expensive engine on a $4 electric part that goes haywire, then do it - go for it. Just don't ask others here to comply to your rolling of the dice method.

Is there data to support this "Isuzu-delivered" system? The Atlas/Vortec series GM engines & 4L60E drivetrain is 100% GM from start to finish. The electronics on the Colorado/Canyon is all Delphi. Nothin' against Isuzus, because I've owned them too.

Yes there is ownership proof. I got this information off the GM Colorado messageboard board - plus a Colorado fans messageboard. It is not the same system used by most-all GM vehicles.

I can confirm this as I am a member of the Coloradofans.com website. Its definately not the typical GM design w/ the percentage shown.
 
So does it use the same algorithms or is it simply mileage-based. I don't really care because, since it's a govt truck, you all will foot the bill if it blows up.

j/k. As I said, I've already changed the oil once at about 7k miles and was going to change it agin in a few weeks even though it's only at 10k now.

Yep, I know it's just an on/off dash light (no percentage data). I owned a 2005 Trailblazer 4.2L w/ just the dash light. It's the association with Isuzu I'm questioning. The 2.9L, 3.7L and 4.2L engines and drivetrains have nothing to do with Isuzu other than Isuzu selling rebadged Colorado/Canyons as I-series p/ups and rebadged Envoys as Ascenders. Isuzu did this up to 2005 in an attempt to keep the brand alive in the US since the Rodeo and Axiom went out of production in 2004. Isuzu North America passenger vehicles are gone for now w/ only a handfull of servicing dealers left.

Lol, so you're trying to lure me into ANOTHER forum AND get flamed!

I do enjoy the Colorado. But that center crossmember on the frame is HORRIBLE for getting stuck on logs and water bars... But it's a nice, basic truck. And the 5 cylinder does NOT seem underpowered to me.

[censored] the 5cyl underpowered? I LOVE my 2.9 4cyl, its a beast
 
Well, a lot of people complain that they can't tow gillion pounds like they could with the S-10. But for what I need it for, it's more than enough. As it is, I can't keep rear tires driving on the roads I do.
 
I recently got rid of an '04 Colorado. I took it off road, and the front diff tube cracked when it goes into the pumpkin. I wasn't even into any hard stuff, but bottomed out the front pumpkin on some dirt and the ALUMINUM cased diff broke, poor design. NO more GM trucks for me. Very much a piece of crapola

The way the fixed diffs are tucked up above the frame on today's IFS 4x4's, you had to go in DEEP to reach the front diff. A skid plate should have prevented that. All the IFS 4x4's I know of today use an aluminum front housing & will suffer the same fate.
