You're far too trusting. They are both blowing smoke. I certainly hope they aren't charging you a fee to reset too...

I change my oil myself. It is nice to take it in every once in a while (every year) to have the dealer do a good check over. They usually do a special in the summer through their email for a free inspection..and I'll take it in then.

It's interesting...my automotive teacher who has been in the industry for 50 years and has 2 kids who work for GM said you should NEVER EVER go by the oil life indicator. They're inaccurate, and GM has been having problems having to fix and replace engines, even when the customer was following the DIC. He also said that if you have a turbo you need to cut the typical oil life in half... So if you go 5k on a change, you need to go 2500 with a turbo since it runs hotter. Not sure if he said if that is the same with synthetic or not....but I never knew that.

>>>>>A) pressing both lower buttons on the steering wheel simultaneously, wait for the DIC to read RESET? (I don't recall it's exact wording at the moment) then simply press the INFO button on the steering wheel to acknowledge that; or B) the other method is just as simple. I'm fairly certain it's the BRAKE pedal you push on 3X to reset the OLM, and this has to be done w/ the key in the ACC position. <<<<

"A" doesn't work. Read carefully - IT DOESN'T WORK

"B" Brake pedal? I thought it was the gas pedal.

BTW, I have an SS. I'm told that "A" doesn't work on SS's. But let me repeat - mashing the gas pedal with the key in ACC DOESN'T WORK.

Believe me, I've read the owners manual numerous times, and had it on my lap while I tried "A" and "B."

This is all moot. The dealer resets it, and I drive away happy.

Kid....

your teacher is blowing smoke, IMO. I'd ask him to provide a resource for the statement. I would bet, if you asked him, he couldn't explain intelliegently how the OLM works.......most people cannot.

As you may remember, I have contacts within the GM engineering community and the general impression/statement is, "....the OLM is the best thing since sliced bread....".

Not saying there has NOT been some minimal instances regarding certain special applications, but considering GM has over 30 million vehicles utilizing the concept........

And the algorithm that determines the oil change necessity is different for each drive train combination.....i.e. the turbo, the supercharger, the engine size and transmission combination, for example.

VictorySpeedway.....

Come to the Hillsdale g2g....I bet I can get it to work. If not, then it needs to be repaired, as a defect.....but I doubt that is the case.

urbexHHR

No offense, but why should I believe you any more than him? He has two kids that work as engineers at GM....and he's been in the business himself for years.

whopper

Here we go again........... Ok - here is a third opinion: CrazyCarKid, you actually NEVER need to change your oil. I speak from personnal experience through the ownership of 9 cars and 7 motorcycles, and the miles racked up on all of them, and none of them have ever failed due to an oil-related problem.

You really never need to change your oil - what is the engine made of? METAL!!!

What are ball bearings made of? METAL!!!!!!!


I rest my case!!!

LMFAO!!! Jeesh some of the threads here are getting nuts - 25 MPG at 117 MPH!! where should I get my oil changed? What oil should I use? Premanent removal of front sway bar!! Trying to fix fuel leaks with Silicone!!! Two batteries in every HHR!

Lets get some real questions, like where can I get replacement flowers for the bud vase on the dash?

'cuse me, I'm gonna go take a pill!!!

maaa haaa haaaa

No offense taken. As someone else has mentioned that's what a FORUM is about. People giving opinions (or statements) and allowing others to judge for themselves.

I would mention however, that the statement would be more valid coming from his sons.......not from a second hand source, which COULD be braggart bravado. However, IF the statement is true, the sons would never mention it....if they valued their positions with GM. GM is real "touchy" about information not approved, especially something that is critical to the value of their product.....and the current market.

I would ask you, have you found (or heard) any info independent of the teachers statement. Any class actions, any court cases, ANY info at all regarding this failure. And remember, GM has utilized this system (with additional improvements) since about 1990, if I remember correctly. So the total sales of the vehicles using this system, speaks for itself (the 30+ million vehicles I mentioned). Don't you think you would have heard something during this time.....I haven't.

Snoopy

I stand corrected...KId. Just received this from a friend. Notice farther in the description, that it is vehicle/engine specific.
