Gas

Shell Nitro + 91 octane. No ethanol it says right on the pump. Can’t get 93 here but she runs fine on 91 . I did burn 93 and 94 for a week or so in Alberta but don’t notice any difference in the 91 to be honest.
They haven't changed the labels. Shell no longer produces gas without ethanol. I looked on their site. It used to say no ethanol and now it is nowhere to be found.

Oh yes, the dreaded “ clean fuel standard “ . Found this for what it’s worth.
Shell V-Power NiTRO+ gasoline, specifically the 91 and 93 octane variants, is reported to be ethanol-free in some regions. However, recent regulations in Canada have led to a shift where all gasoline grades, including premium options, may now contain up to 10% ethanol. This change has been noted across various forums and discussions among users. Thus, while some stations may still offer ethanol-free options, it’s increasingly common for Shell’s premium gasoline to include ethanol. Always check local pump labels for confirmation.
And this which is interesting. Nice to see someone keeping track .

I think the pump has some outdated messaging. Pretty much every refiner has some ethanol content in motor vehicle gas. It's a Federal requirement.
 
Just don't let it sit without stabilizer for too long and we'll be fine.

Any of my carbureted engines get drained at the end of the season. So far, so good, but the one year I got lazy, it was a disaster.
There seems to be a number of different views on the subject for sure. I fired up a vehicle a couple of months ago that had fuel sitting in the tank for almost three years and no issues at all. I for many years worked all over the North and at the now shuttered Lupin Gold Mine in Nunavut we drew fuel from the massive fuel storage tanks left there which apparently hadn’t been filled in 8 or 9 years! and it was still viable. So who really knows but I wouldn’t be putting any of it in my Corvette, lol .
I noticed that GM say not to put anything in the tank that contains a number of chemicals that they list. Are you aware of any components of fuel stabilizer that would not be recommended? Just curious as it’s another topic I’m not well versed in.

Everyone uses Stabil.
 
I've been adding 100ml of Seafoam to my 20 liter jugs. Less than recommended but more economical. Seems to be working.
Really amazing stuff. I have seen it added to fuel tanks in old neglected vehicles and after 5 minutes they were running smoother and quieter. God knows what it’s doing but there seems to be something to it. I have a feeling that a lot of additive products are nothing more than snake oil.
 
If everyone apparently uses STA BIL, then please, can someone comment specifically on the Corvette C8. The person who started the thread does have a valid point, there are a number of chemicals GM advises against putting in the tank. Is Sta Bil, which everyone apparently uses, acceptable in our tanks? Please comment. C8 only. Please and thanks!

What difference does it make what car? The engine isn't much different than any other performance engine. Stabil will work fine for stabilizing fuel in the LT2 as well as any other car..
