New Oil Viscosity Recommended
- Thread starter Briachas
- Start date
Ironically, I have been tracking my recent oil consumption since my last oil change. Presently, I am at 52,345 miles and I have tracked the oil consumption at 1 quart / 1,300 miles. Also, verified the last 1,300 miles it required another quart. I usually change oil at the dealer every 5,000 miles. This is not good knowing I still would have +/- 2,400 miles to go before the next scheduled oil change.
I noticed once the truck turned 40,000 miles it used 1 additional quart per 5,000 miles. Other than that, the truck has performed great. Something is definitely headed in the wrong direction.

That's because it's about oil not fuel.......LOL!

I remember seeing some comments about how the vette and Camaro platform run the 0-40 oil rather than 0-20 and some folks believed that to be the issue as to why the trucks/suvs have all the issues. It makes sense in my simple brain. If the crank is eating up bearing and coming apart, the metal shavings will affect the lifters and cause catastrophic failure before you would hear a rod knocking.
I can’t remember if it was on Facebook or buried in one of the oil threads here.

I've run 0W20 oil in several vehicles for thousands of miles. The oil is not the root of the problem. It's shitty design, parts, and manufacturing. And the oil change is a bandaid fix that their lawyers told them implement as a CYA for pending lawsuits.
This was likely a result of their negotiations with NHTSB and Direction from the Board. Changing oil on vehicles that have logged thousands of miles isn't gonna charge anything, hence the emphasis on shit sitting on dealers lots, not the ones in your driveway. That's the low cost "remedy".
Remember, GM doesn't give two shits about the health, safety, and welfare of you or your family. They only care about extracting the maximum amount of cash from your pocket. They are no longer a car company selling vehicles for the enjoyment and benefit of customers. They are a huge annuity and health insurance company that happens to sell sell cars to fund their legacy social and welfare commitments to the Unions and employees. For every employee, they have to cover legacy UAW commitments to 2.5 employees (and thats old data). Wall Street and executives take what's left and you fund it with overpriced vehicles with low reliability and expensive repairs.
Don't believe me ........ just look at the the way they handled the Duramax CP4 fuel pump issue. The lawyers on both sides made 28 million and very few customers in a few select states got "remedy"......everyone else was left holding their own dicks for $12-15k repairs.

Yeah @AXE I totally agree. Oil alone isn’t going to magically fix all these problems. While it might help this is just GM avoiding engine replacements on nearly a million vehicles because they don’t have the data to narrow this down to specific VINs. Engine design flaws would affect everyone. Can the NHTSA call bullshit on the corrective action or is any action allowed until enough additional failures occur? I don’t know but an oil change and a plastic filler cap is a testament to what GM thinks about us.

Might want to consult a dealer, just to see if they have any better data on what might be coming for the average Joe. Theoretically, if you ran 0W40 on your own accord and your motor grenades, they could deny warranty. Not sure that is very likely, but it is plausible!
Remember, there's plenty of oil analytics on this 0W20 oil and for the most part all the samples look good and wear metals are in line with the averages for likely thousands of 6.2L motors in the laboratory's database. To me, that says something about the oil and something else about the reliability of the motor parts.

I am curious about the same thing. Was gonna change my oil next weekend. But I haven't bought new oil and filter yet.

The thinner oil also helps with cooling thermal hot spots due to the closer tolerance in the more modern engines. Some engines such as the new Ford 7.3 gasser even have small orifices to spray oil even on the backside of the pistons. This engine issue is a huge problem for GM and now that Uncle is involved is even more so. I have been associated with the involvement of Uncle in aircraft accident investigations. To just make a statement "they don’t have the data to narrow this down to specific VINs" is not fair as it is possible that a different supplier was used that employed different process and even materials (metallurgical differences, machining speeds and lubricants used during manufacturing even the heat treatment process) to meet the specification for the failed components in question.
This gets incredibility complicated and often time can absolutely be attributed to a simple human error. The root cause of an error we encountered on the F22 NLG was just unbelievably simple (no crash involved). Supplier did not update a machining operation job process instruction as they are required to do. Short story was the operator of this CNC controlled equipment for over 15 years retired. His replacement had no idea that the op cards were not updated and used the instructions as written. The old operator knew this and used the correct cutting speed, cutter and lubricant. Result the higher machining speed on this specific material and the lubricant not being of the adequate type as well induced excessive heat caused a high level of embrittlement resulting in the early failure of the part in question. The highest level of CAR was issued, and the Supplier was required to support a joint USG as well as Lockheed Martin complete quality system audit and recertification which is in itself $$$$$'s!
Point is everything is not as it seems until all of the information is available. In this case we may most likely find out the detail due to the fact Uncle is involved.

Yep, $15/qt at that price I definitely won’t be doing 3,333 mile changes. Hell, might as well go to 7,500 per GM recommendation and let them replace what fails and dump this truck before warranty expires. Seems like the best strategy.

I just want GM to restore my confidence in the brand. Most owners are well educated and can understand a detailed explanation but GM never seems to want to share that. I’m not sure the NHTSA will force their hand. It just doesn’t seem like GM cares about my future business. It’s my belief that GM hopes that the oil change will reduce the catastrophic failures but inside their closed door meetings I’m sure that the statisticians are predicting a continued smaller percentage of catastrophic failures due to design flaws, manufacturing issues, assembly mistakes, etc. This is not the aviation industry so there is a lot less accountability.

It wasn't supposed to make sense. That's why they issued it. Smoke screens are an effective way to misdirect the opposition and delay the remedy. That's why the lawyers pull big checks, run the clock out for years, and then shake hands and go have drinks afterwards. Meanwhile it's 5 years later and you've moved on so they were successful! Oh, and they make sure the settlement decree claims GM is absolved of any wrongdoing, cause they paid the fees on time.
