Don’t let anyone tell you not to use fuel stabilizer, it is important. Even as good as today’s fuels are you can still get varnish etc. on cylinder walls when storing a vehicle long term. I have been using it in my ‘94 Vet for
almost 7 years and it starts up immediately in the spring. Top off the tank with either 91 or 94 octane to prevent condensation. If your not sure talk to your mechanic and I’m sure he’ll tell you the same thing.
I agree 100% Tommy, I have done the same as you for 10 years and never had a problem.
 
Why so late? We were selling an E10 in 1981. And Sunoco was in Ontario with E10 in 1998.
Maybe I`m off on the dates or they were adding the Ethanol along with the all the other proprieitary additives at the terminal..... I know when we were testing it coming off the units there was no Ethanol in it.

Originally our methanol/ethanol was added directly into the tanker truck! However, it is normally added at the load rack along with other proprietary additives.

Hey you guys, MOST OF YOU ARE NOT LISTENING. All of the examples I see here are not for C5 through C7. For those such as C1, C2, C3, C4 & C8 plus other manufactures you are absolutely correct - fill the tank. However, if you have a 1997 to 2019 Corvette, only fill quarter full You have been given technical explanations regarding the sender unit being submerged at about the half full/half empty mark. So please don't post to confuse the C5 to C7 owners. If they choose to ignore this advice I hope they do OK next spring. Read this post twice please.
 
Well, that was a great little video from GM. Oil change before storage - don't matter, top up with fuel or half full before storage - don't matter. The biggest thing I took away was to lift the car if possible to prevent flat spotting the tires, but I have never had that problem in the past.

I inflate my tires to 45 psi to prevent flat spotting.

I also inflated to 40 PSI, but the video said it can be worst if you do over inflate your tires. So nothing is really important besides a battery tender and putting the car on jack if possible... ho and a last drive after washing your car to dry the components...

Interesting, I think Michelin says max 51 psi for these tires
 
Wow! Almost useless and extremely disappointing. Tirerack etc list NO winter tires for C8 and I cannot find any anywhere. Why didn't the video recommend any? Regarding oil change prior to storage: "There's no right or wrong answer" Are you kidding? One option must be better than the other. No discussion on fuel stabilizer, ambiguous answer about oil change, No discussion of what to do if not storing near electrical output for smart charger. Regarding fuels for storage, the "expert" says "vehicles age during storage" Duh, Did he mean fuels age? Why have I never had flat spot tires?

But the worst part of outright misinformation is at 2:20 when the expert advises to change your DCT transmission filter at 7500 miles or 1 year. Thats completely misleading as that recommendation is 1st change ONLY. He does not clarify that and leaves the impression the DCT filter should be changed every year or 7500 miles. From the manual:

1637351900277.png

so other than 1st time you would be changing DCT filter 5x too often as recommended
What a wasted opportunity.

Regarding fuel prior to storing I just received this from GM Customer Care:
"Thank you for your email.
It is best to store the vehicle with a full tank or as close to a full tank of fuel when storing the vehicle for the winter, with Fuel Stabilizer added to the tank."

There's not a lot of snow in BC during winter months, you should be fine with good all season tires. And yes, I agree with you that the video was too short and disappointing cause they did not elaborate on a lot of subjects.
 
Check out this article and video - it is absolutely true!!
I wrote a note about exactly this a couple of months ago. Not that I want credit, but what do you do in the spring when your sender unit is all contaminated and your C5, C6 or C7 fuel gauge is reading incorrectly? When I first got my 1999 about 10 years ago I thought same as everybody else and filled my tank full for the winter to eliminate condensation. I as not aware that these fuel tanks are sealed. In the spring my fuel gauge gave all kinds of false readings.

Fortunately I have a friend who is a Corvette General Motors specialist and he gave me the solution. Here it is. Just get a 295 ml (10 oz) bottle of Chevron Techron Complete Fuel System Cleaner and add it to a full tank of gas. Voila - works like a miracle. Cleans the sender contacts and you don't have to pull the fuel tank and sender/pump assembly. Only problem is I don't know where to buy this stuff in Canada. Luckily for me Detroit is five minutes away across the Ambassador Bridge where you can buy Techron at Walmart. I do see it on Amazon for about $25 US but the packaging looks like it has been updated.

Maybe you could try the CTC cleaner but I do not know if this works, Perhaps some one on this forum has experience with a Canadian solution. I have no information on the C8.

Why not get a set of winter wheels and drive it? Winter traction due to skewed weight distribution is one of the major benefits of a mid-engine vehicle. Add to this the composite body and auinum chassis that doesn`t rust, it should be a good ride all year round.

I had a C4 with Goodyear Eagles and got caught in light snow once and took me (and everyone behind me) 3 hours rather than 1 1/2 to drive home from skiing. White knuckles all the way due to cliff on one side and ocean drop-off on the other. Another time, driving home from work my small street was off a street that had a steep slope and the car could not make the turn due to light snow. Rather than slide down the hill into busy traffic I went into a ravine. Since then I have always had a "winter" car with snow tires and now have a Honda CRV AWD with good snow tires so the C8 gets a rest.

Winter tire compounds have advanced quite a bit in the last decade with silica and crushed walnet shells being some of the additives providing traction on snow and ice. A deeper tread and narrower tire than the OEM all-season & runflat tires is also a must.

I like running studs on the front even with the slight oversteer when I am in the southwest SK due to the hilly geography similar to what you are describing (being at an elevation of close to 3000ft). I have far more confidence driving the vette than driving a RWD truck, the only issue is clearance when the roads arent plowed.
