Are you running your C7 on E10?

Any issues with running a C7 on E10. Higher octane unleaded is getting harder to find at some stations now...

Getting harder to find, really? Every single Shell station I ever visit has plenty of V-power 99 RON which is what my C7 runs on?

My local garage has stopped selling two grades of unleaded, so only E10 available within a five mile radius where I am. A lot of the smaller forecourts with limited pumps appear to be heading in that direction as the majority of motorists don't want to pay for the premium unleaded. As you say, all the bigger stations still have plenty of E5.

Hmmmmm, guess being quite close to London it's not something I've noticed.

I'm no expert but not sure I'd be keen to be running on anything less than 97 RON.

Totally agree

US gasoline has been 10% ethanol for ages and is typically under 97 RON so I’d guess the C7 engine is designed to run on such stuff without issue?

Here is some information from the Corvette Customer Assistance Centre regarding E10 fuel. Doesn't mention the C7 but the high performance Z06 and ZR1 are on the list.
