Yes, heard that on US forum several times.

Z51 oil change at 500 miles, believe there was an official bulletin from GM, so make sure you get it done. I have also heard it is free.

Oil Changes

If you are getting free factory oil changes, go for it. Engineers have a pretty good idea on what works best.
When building my own engines, I dumped the break in oil after the first half hour. It's one way of getting rid of any grit still in the oil passages of the engine. I used solvent and wire brushes in all the oil passages too. With engines cleanliness is next to godliness so I was told many years ago and I stuck with that. With our vehicles, I change the oil and filter about every 5K miles, using good quality synthetic oils although I believe that they are overkill. The only engine problem that I have ever had was a wiped cam in a '69 GTO that I had for a winter beater in the mid '70s, and that car had a lot of miles on it. The vehicles going away for the winter get their oil changed before storage so that The bearings have fresh oil around them. Works for me.
 
Yes, 5th is free. See bulletin. Also see owner's manual addendum page, recently released. New manuals from here onwards, will have the correct page inserted. Most canadian dealers have no idea about this.

One word of caution. The oil u get free is a dexos semi synthetic. That is dinosaur oil mixed with synth. That is what the spec is , unless tracking the car. Then u use full synth. U have to pay extra if u want Mobil1 full synth.

Dino oil does not touch our cars. I opted for doing my own oil changes instead, so I know what is being poured into my car.

I did my own oil change at 500 miles, with synthetic. Wanted it done and didn't want to deal with "why it's too early to change the oil". Feel much better that it is done, all those parts got to get to know each other those first few hundred miles, sometimes there is machining grit in the engines so a little investment of time and money was worth it, peace of mind.
Mine is a ZF1 not a Z51 so no dry sump.

My dealer Gateway will only put Mobil 1 in the Corvettes, no extra charge! Before the notice came out they did my first free change at 1,500 km.

Being the great dealership that they are , they also provide free oil changes for year 3 & 4 of ownership on the Corvette for a total of 9!
 
@ smackYYZ: Thanks for recommending our dealership here.

At Gateway Chevrolet we offer 2 additional years of oil changes (4 oil changes) if you purchase any new 2014, 2015 or 2016 vehicle and continue to maintain your vehicle at Gateway Chevrolet. These 4 oil changes are in addition to the 4 oil changes offered from GM Canada.

Also the oil we use is always the recommended oil as per GM Canada. For all C7 Corvettes equipped with a drp-sump engine (Z51 or Z06) GM recommends Mobile One oil that is Dexos Approved with SAE 5W30 viscosity rating. If you intend to drive your C7 through winter (temperatures of -29C and below) then you may also use Mobile 1 Dexos Approved SAE 0W30 for easier cold starts.

For tracking purposes GM recommends Mobil 1 SAE 15W50.

The Break-in Oil change must be performed on engines equipped with Dry Sump Engines (Z51 or Z06) at 500 miles/800KM. This is an additional free oil change authorized by GM Canada.

Read an article on another site which said Mobil1 to now be used in all C7 Corvette's-(Stingray, Z51, Z06). I believe it was a bulletin or some technical term for it but not 100% sure.

I sent this GM letter to my local Dealer and they have turned down doing this change for the reasons stated by GM ( oil detergents foaming up because of a reaction to silicon in a gasket ). They said it is in the States only - not Canada. I argued that the cars they are sending to Canada have the same oil and silicon in the gasket as US cars. Anyway, it seems to me that this is a mute point in that using up 4 or 5 free changes in 2 years or 24 K is plenty for a " non-daily " driver that gets only 4 - 8 K per year for most of us.
 
Those free oil changes may just pay GM dividends. Getting cars traded in down the road, they will know that the cars have had their oil changed regularly. It's amazing at how many people don't change their oil nearly as often as they should, especially if they know that they are going to be dumping the car in 3-4 years for a new one.

Oh so true. I was at my mechanics shop last month and there was a fully loaded 2010 Audi A4 in the shop with a seized engine. Woman who owned it had never had any service done on it, so never an oil change. The crazy thing the service was free!
 
I had a friend with a Nissan Maxima that he had bought used, drove it for 5 yrs and convinced himself that if he actually changed the oil it would spell the end for the engine. He wasn't very knowledgeable about cars and thought that the engine had gotten used to the oil it. Geeez , where do you start :)
 
GM does NOT give anything away without good reason. Talk to mechanics and your jaw will just drop to the floor at what you hear about the lack of maintenance that people do for their cars.

Hello, I had a question regarding this topic of " blended " vs " synthetic " oil in our C 7's. Firstly, I am new to the site, so not too familiar with navigating a forum. I was reading all the great discussions and thought it would be great to be a part of it. I just took delivery of my 2015 Z51 2LT in early November ( my first corvette ) and having more fun than I expected ( on the West coast ). My question was do we really know the long term benefits to the engine using synthetic vs a blended ( for a non-track driven car ) and is it only noticeable if it is driven hard for a lot of its life? Looking for some wisdom from those here on the site that have experienced this. Cheers, Peter Szarka
 
I have used the blended Dexos oil in my SUV and it is fine. I'm fussy about the C7 so I will have them put full synthetic in it, likely though the blend is ok if you are not driving hard. GM has adopted Mobil 1 as the standard for Z51 engines like yours with the dry sump so I would push GM to put that in when you get your oil changed. If it isn't in your manual stating, it should be, there was a change making it standard and your dealership should be aware of that. There should be no extra cost when you get your freebie oil changes.

FAIRFAX, Va. & DETROIT--(BUSINESS WIRE)--ExxonMobil today announced a new lubricants technology agreement with General Motors (GM) for the Chevrolet Corvette. As part of the relationship, Chevrolet has chosen Mobil 1™ motor oil as factory fill for the highly anticipated 2015 Corvette Z06 and the 2014 Corvette Stingray with the Z51 Performance Package.

“As the Corvette Stingray hits roads around the world, we want Corvette owners to know that Mobil 1 motor oil is specifically designed to meet their high-performance demands and will help keep their engines running like new.”

Building on a 21-year lubricants relationship with ExxonMobil, Chevrolet also named Mobil 1 5W-30, which meets or exceeds GM dexos1

I wouldn't expect a dealer to put nothing less than what it came from the factory with. There's a good reason why it leaves the factory with Mobil 1™ 100% synthetic motor oil.

I wouldn't settle for anything less then that.......

Hi Owais

Can you please refer me to the GM official link that states 2015 C7 z51 require the Mobile 1 for the free oil changes. My dealer is telling me no. Thanks.
