Last Thursday (11/19/15), I took my 2015 Z51 to a Chevy Dealership to have the 7500 mile service. I told the service advisor to make sure that he wrote in the notes to use mobil1 and to follow the updated fill requirements. After receiving the car back, I noticed later that evening that there was an intermittent foul smell (I liken it to burnt popcorn or oil) coming from my vents. I initially thought that the smell was from outside the vehicle. After smelling the smell multiple times over the weekend, I returned the car to the dealership Monday morning. I told the service advisor what I was smelling. He stepped into the vehicle, started the vehicle, and acknowledged that there was a strong smell coming from the vehicle and that they would look into it and address it immediately. An hour later the service advisor returns and said that they couldn't find any issues and that he couldn't smell anything. I reminded him that he smelled the same smell I described when I arrived, but he then told me that he was "mistaken", and that he thought he smelled something and there was nothing else to be done. I asked him to take me to the vehicle and start the vehicle. The burning smell returned (and I was standing several front from the driver seat) and asked him if he could now smell it. He said he smelled nothing. I then asked what kind of oil (and the quantity) they used when they changed the oil the previous Thursday. He said they put in 10 quarts of oil but it was not mobil1, and that Corvettes don't take Mobil1. I sat down with the service manager who proceeded to tell me that I was incorrect and no corvettes take mobil1 and they filled it correctly and whomever told me about the updated oil change requirements were wrong. I instructed him to look up service bulletin PIP 5290a. After about 5 minutes, he agreed that his team was incorrect and they would change to the reduced quantity of mobil1 immediately. On today (Wednesday 11/25), I take the vette out on the road and notice the burning smell is still there and continues to go in and out. Has anyone else experienced this problem (the foul burning-type smell after an oil change)? Can one of the Chevrolet contacts on this form contact me to help get this resolved? I spent 4 hours at that dealership Monday, and the problem isn't fixed.

hlac7, it is possible that during the service oil was spilled on the manifold or exhaust and that is what you are smelling. At any rate feel free to send a PM to "ChevroletCustomerCare" reiterating what you put in your post. Include your VIN with your description and request for their assistance. It also sounds like you should find another dealer for future work.
I wouldn't be surprised if they didn't know that there are two oil drain plugs. They maybe didn't get all the oil out before refilling. Learn how to check your oil level in your dry sump engine yourself. Then you'll know if you're still overfilled or not. Also check to see if they spilled oil on your engine or exhaust manifold (of course that shouldn't have happened, but you never know).
The worst thing would be if the oil has been pushed back into the intake airbox.
Their actions are disappointing on so many levels.

By the way, if I were you, I would start a new thread in the Western U.S. section of the forum (it can be found here: Western Stingray Owners ) and ask for suggestions of good places to go for service down there. I know forum member Ret9580 can tell you multiple places of where to NOT go. Actually, if I were you guys down there, I would try to help each other out by not only saying what dealerships offer great service, but also identify the ones which have given you guys trouble.
I have the exact same issue. I had the oil changed at a dealer about a month ago, and have driven it about 70 miles on 3 trips since then. It is a faint burnt oil smell. I really don't think its on the manifold as I would think it would have burned off by now. If for some reason thy didn't pull both drain plugs, would it necessarily smell burnt? I only have 1050 miles on a year old 2015 Z51. If they over or under filled it would it have that type of smell? I had absolutely no smell before the oil change. Any other ideas?
Welcome to our forum Northern Rick. Actually if there was some oil spilled on your manifold during the oil change, it would not necessarily completely burn off in just 70 miles of driving. There are a few things you should be doing: check your current oil level per the Z51 directions (not the same as checking oil in a wet sump engine) and check your air bridge/air filter for any oil that may have 'burped' up from an overfill.
Have them look in your air intake, if oil present have them clean the intake and change the air filter after correctly adjusting the oil level lower.
I have been having similar problems after a dealer oil change. Smell comes and goes now, dealer is ignoring the issue. Dry sump Z51, now parked for winter hibernation.
Update:
I took the vehicle back to my original dealership (Community Chevrolet - Burbank, CA) today. They inspected the vehicle and completed the full 7500 mile inspection (since apparently the other service department -Montebello Chevrolet) did not. They told me they found a bag stuck to the exhaust which they scraped off and that the smell should go away as the remainder of the plastic melts away. I'll give the benefit of the doubt since they do pretty good work. I'm still skeptical because the smell started almost immediately after the other dealership completed the oil change, and burnt oil and burnt plastic should smell quite a bit different. I'll give it a few weeks and post an update later. Sidenote: it is quite disappointing that Chevrolet as a whole does not appear to be equipped to support their flagship vehicle. There are good service centers scattered here and there, but it seems that many of us early on have experienced subpar service from service centers that are not prepared to properly maintain these vehicles. It's sad, really, since these beautiful machines catch the gaze of so many people no matter where you go.

I had the same on my C6. My very first oil change the dealer over filled it by a full quart. I had the car flatbed back to the dealer and they corrected the issue. I seemed a dealership (CHEVROLET) in my area that one person does nothing but vettes he is even in a different area then the "regular" techs.
I will say that my C6 was one of the best trouble free cars I ever had.
I know it hurts to see you car not being serviced right
It's all about training training training.

I'm having the exact same issue. Dealer changed my oil ( Shellworth Chevrolet ) and now I have the on/off burnt oil smell. Has anyone ID the source from the previous threads? I take my car back 2/15/2016
Oil Odor in Cockpit after Oil Change
Took my '15 Z51 in for a routine oil change a few days ago and have that oh too familiar burning oil smell in-cab mostly noticeable when idling.
This happened once before after my 1st oil change. (Now at around 13k miles) I remember reading in the forum back during the first occurrence about an issue with doing an oil change with the dry sump maybe? The last time I brought my car back to them for the smell, they cleaned some oil reside (aka "spill") from around the sump and replaced the cabin are filter.
Guess they didn't learn from the first time because I'm taking her back in.
Dummies!

Everyone should be comfortable making an oil level reading in their Corvette, as you are the last line of defense against incompetent dealership service departments, and the number of instances of C7s being overfilled by dealerships is disturbing.
If you smell oil after a dealership oil change, check the oil level. The procedure is to park on a level surface, turn off the engine and wait 3-5 minutes before reading the oil dipstick. Waiting less or longer can lead to an incorrect measurement.

Dealer admitted oil level was to high upon returning on 2-15-16. Dealer Found oil in the intake but did not change the air filter or check the MAF for oil. To cap all of this off, once I made it back home with the Vette I waited 3-5 minutes and oil level was still on the very top level of the marked area.
My dealer's Corvette guru checked into my problem this morning. First, he looked at the level and air box per the service bulletin and all was ok. He called me over the show my that the oil sump cap was not very snug (loose o-ring) compared to a spare he had on his bench. Told me to drive around to test for a day until a new cap came in. Well, I have a nose like a drug dog and it's already better! Also, the constant burning oil smell that was noticeable with the hood up while running is minimal currently. ...I'm being optimistic [emoji4]
