I'm not so sure about that. As both I and NSC5 said, having no records "ain't gonna fly."

Moreover, the dealer isn't going to deny anything. They make money by doing repairs. It's the manufacturer who will doing the denying, and it's the dealer who is usually your friend in such circumstances. They want to do anything possible to convince any manufacturer to approve warranty repairs.

I am pretty confident that my receipts showing sufficient oil and filters for what I own along with the service records I create will be sufficient for GM and of course I do reset the OLM system when I change the oil and since I have OnStar it also keeps those reports.

I suppose you could videotape your entire oil change using a current newspaper for the day to catch any splashed oil and make sure that it is also in the video. Then seal the digital media and the newspaper in an envelope along with the boxtop from your oil filter and caps from the oil containers, wax seal across the envelope flap, and have your signature across the seal notarized. But that seems just a tad overkill to me
What if he uses old newspaper?

Respectfully disagree, Foosh.

GM corporate doesn't have folks looking over the shoulder of the service writers. They make the call, and get reimbursed. I even have a story about that one.

One of the Chevy dealers here in town had a service writer that was replacing parts that didn't need to be replaced for several years. I am in a Corvette club here, and it became common knowledge that he'd replace items that weren't bad under warranty, just before the warranty expired. At the time (C4 era) the steering rack was a weak link. It wasn't a matter of if it would fail, it was when. Many members took their C4's to him, and they'd get a new rack with the only complaint being "steering feels funny". No test drive, no inspection. He got commission on every repair he sold, so he was raking it in. That dealership ended up having highest warranty claims of any dealership in the country. GM finally got wise, and did an audit. He got caught, and was promptly fired.

There are 100's of legit reasons folks might not have their proof of life of oil changes. Divorce, house burned down, dog ate them, lost in a move, etc. Unless the tech or service writer suspects (sludge, burned bearings, excessive ring wear, four quarts low) that the oil was never changed, simply not being ably to produce receipts isn't going to stop a warranty claim.

Concur. Corvette owners changing their oil is a good assumption, receipt or not.

I haven't. IMHO, we are likely hand wringing over nothing...
I was in the industry (dealership parts and service at all levels up to management). I've seen a few cases, but none that involved a "do it yourselfer," and none that would affect a Chevy.

The ones I've seen that were problems were with low market share, "oddball" cars (one very upscale, one very low end), owned by people who lived more than 150 miles from the nearest dealership and who used national chains for their oil changes. The national chain shops had no idea where to get oil filters for those cars and probably did change the oil (no telling if they put the correct oil in the crankcases), but left the factory installed "break in" oil filter (unique and available nowhere but the factory) on the engines.

Both of the case I remember had total engine failure before 33,000 miles, and both of them were initially ruled "Warranty void, no evidence of oil/filter changes. Factory installed filter still on engine." Both owners were able to produce a stack of receipts from different national chains for "oil and filter change services" well in excess of the minimum required by the manufacturer. One had 9 or 10 receipts, the other I think had 6. The vehicles showed 7,500 mile oil change intervals for "normal driving" and one showed 3,000 mile intervals for "severe use" or something along those lines. That guy had receipts for every 3,0xx to 3,5xx miles.

Both engines were replaced at no cost to the customers/vehicle owners, and there were major fights between the manufacturers and the national chains that operated the "repair shops" where the "oil and filter change services" were allegedly performed. I honestly don't remember who ended up paying the bills.

This would be highly unlikely for a Chevrolet engine, although I think GM does use unique filters on the engines when they are assembled to "catch" people who never change the oil and filter.

Great info, thanks for that!

Do you remember what the actual causes of the failures were? I'm guessing both were due to the factory filter coming apart, and getting sucked into the engine.

if we are talking catastrophic engine failure then GM will likely want a thorough analysis done and they will likely review maintenace records especially if the engine failure is related to oil loss or starvation. At that point then yes, you could be out of luck.

But we are talking an extreme case here.

Main bearings failed on both of them.

One, all the oil passages were so full of dirt and crud that it ultimately "blew out" the rubber gasket on the oil filter and was leaking oil out there. The oil literally couldn't get in the block, through the passages to the bearings.

Where did the dirt come from? Did you suspect that the oil wasn't really changed, and the receipts were fake? Or was it the paper element from the filter that finally came apart?

I would think with a filter that old it was pretty much bypassing everything around the filter and of course since it was the original factory filter it had probably also picked up a lot of debris early on.

Even new filters generally are in partial bypass mode with cold oil, another reason you don't want to operate a cold engine at high rpm. Whenever the pressure drop across the filter exceeds the bypass valve setting then some unfiltered oil is going around. With a never changed filter pretty soon it will always be in nearly full bypass mode.

I travel to the TN mountains fairly often and often take my GMC Sierra diesel pickup. My second one was a 2006 when the LBZ version of the engine was first introduced and I had one of the first produced. I was parked in a parking lot in Newport, TN and a local came over to ask me about the truck and one of his questions was if I had changed the oil yet. He was curious if the oil filter was tough to get off and I told him yes, just like that on my 2001; apparently they had a gorilla at Moraine assembly plant to put on those filters. He then told me about the hassle he had with his 2001 which got a new engine in 2003. The selling dealer had done all of the service but never changed the oil filter because the tech decided it was so tight he didn't want to deal with it. The customer came out OK but after a big hassle. I am sure that is a very rare occurrence but absolutely horrible behavior from a dealer.

If you don't want to keep your receipts at least take a photo of them with your phone and save those in a file.

That combination should be sufficient if there is a question about documenting maintenance.
How does proof of buying prove you changed the oil? A friend with a Dodge truck was told anything but a receipt from a repair shop (even like a Pep Boys) would void the warranty in case of a problem. I'd assume GM is the same.

There is likely a threshold GM has set. An engine, transmission, complete CCB replacement or any other high dollar claim will be reviewed by GM and not just paid because some dealer employee wrote a repair order.

Not unlike how the IRS can't audit all 330 million of us but if someone claims a $25k deduction for charitable donations, you'd better believe that return will be audited.

If GM were requiring this, and legally they cannot, then it doesn't seem the owner's manual would include oil quantity, filter type, AND explicit instructions on how to change the oil.

Dodge, well now Ram or whatever they call themselves and soon to be Chinese I guess, is still subject to the M-M act.

But no need to believe me, because the Federal Trade Commission who is the primary interpreter and enforcer of M-M states the following on their website:

Quoted: "Do I have to use the dealer for repairs and maintenance to keep my warranty in effect?
No. An independent mechanic, a retail chain shop, or even you yourself can do routine maintenance and repairs on your vehicle.
In fact, the Magnuson-Moss Warranty Act, which is enforced by the FTC, makes it illegal for manufacturers or dealers to claim that your warranty is void or to deny coverage under your warranty simply because someone other than the dealer did the work. The manufacturer or dealer can, however, require consumers to use select repair facilities if the repair services are provided to consumers free of charge under the warranty."

See: https://www.consumer.ftc.gov/article...ne-maintenance for the complete listing

Again, M-M doesn't say what many would like because it doesn't protect your warranty after you add 250 horsepower to your engine but it does very much provide protection to the average consumer who wants to use independent shops or do routine maintenance him or herself.

Yeah, great info indeed, and in all cases owners had non-dealership records, and still faced major fights to obtain warranty coverage. You were previously arguing that records weren't necessary. You have me very confused as to what your point is.

What are you respectfully disagreeing with? I don't know what you were talking about, but I thought we were talking about big repairs like engine replacements. GM and every other manufacturer makes the call on big repairs.

Of course, they don't have to obtain GM approval for every minor warranty repair, but even for the piddly stuff, they still require dealers to retain or return replaced parts if requested by GM for audit reasons. I just had a interior light assembly (burned out bulb) replaced under warranty on my C7, and I wanted to keep the old part, but was told they had to keep it in case GM wanted it. Your C4 example is ancient, and it's not the 1980's anymore . . . manufacturers are far more strict today in approving warranty claims.

However, I know all too well what happens with major repairs because I had both C6 Z06 LS7, as well as BMW 740i engines disintegrate during the warranty period, and the dealerships did not have the authority to make those coverage decisions. It took a week of forensics by the manufacturers in both cases before they agreed to cover those engine replacements. In each case, both cars had all scheduled services done at the respective GM and BMW dealerships. If it ever happens to you, you'll wish you had too.

You are dead wrong. Not having maintenance records can void a major warranty claim. Minor stuff is irrelevant and often not worth fighting about. If you're going to do it yourself, you better have a good, safe place to store your well-documented, DIY records, because, "the dog ate my homework" or "I lost them" excuses don't work either at school or at the dealership when it comes to big $$$ repairs.

If you can't prove you have change the oil at the required intervals and you have an engine failure you could get screwed.

You should always (and need to) keep proof of oil changes. I take a photo of the auto store receipt that shows the oil and oil filter purchases then file it in a photo album called "Maintenance Receipts". I also file the receipt in my Corvette folder.

Made all the oil changes in my 2014 Z51 and now did the first at 500 miles in my Grand Sport. For years have just kept a log in the Owner's Manual for my cars. Did not bother with receipts. That said, never had a engine warranty related to lubrication!


However now that Mobil allows a scan and attachment of a pic for the on-line filing for a rebate, I started putting them in an envelope. I keep it with the Owner's Manual where I still maintain a log. Just paid $22.88 for a 5 quart jug at Walmart for the Street Rod and same day with a few key strokes submitted for my $12 Mobil 1 rebate, and received a response stating it's being processed! $2.20/quart! Not bad!

All said, but why NOT keep all receipts and an ongoing record of changes, etc. Not that hard or time consuming; and, the legal system LOVES paperwork.

Pretty easy.... Change your oil and the failure will not be because of the oil. That simple. Now if you don't change your oil it can be easily determined that was the failure. No need to keep records at all on oil changes.

If your engine failed because you didn't change it, they will see the viscosity breakdown when they drain it. If you ran t dry and seized it and put in oil after the fact they will see that too... and believe it or not most engine failures are not due to oil issues anyways.

SO instead of letting a grease Monkey strip your pan bolts, over fill or under fill at either a dealer or oil pit place. Keep changing your oil, toss the receipts, don't video record it, don't create a "data" sheet, because your engine failure is not because you properly changed the oil it will be because of something else.. Get it?

I might add don't follow the advice from NASTYC7 to throw away your records unless you just enjoy pain and suffering. It's pretty insane to leave yourself at the mercy of a manufacturer with no defense.

I knew you would respond.. Funny huh.. Got to love internet "know it all's...." You can spend your life worrying about the little things and I will enjoy mine. Have fun keeping your records for a non issue. Shoulda woulda and coulda do not imply here. Do you keep records of your tire inflation too? You know just incase right...

Might I ask how many motors have you had that seized or blew up from you properly changing your oil? Matter of fact how many failed because you didn't change the oil in a timely manner? I'm guessing ZERO!!

I know you think you are the "answer" to all issues here on this forum, but guess what. Your opinion is yours and that's all it is... I am giving mine..... I don't agree with you and you not with me (obviously by your stupid reply)

Now if you properly changed your oil and somehow your motor failed and they blamed you for not maintaining your oil changes or using the proper weight oil. Do you think you would forgo a $300 test agency ( which you would have to do anyways if you kept home records or even used an outside shop other than a dealer) to test the oil and give the manufacture a certified test result to show that at the time of the failure the proper oil weight was used and the fact the oil was within the viscosity range? But again please enlighten me on how many engine failures you have had due to you changing the oil per spec?
