Do not do that. A whiff of regular gas can contaminate the readings. I can't even imagine how screwed up a full load of that regular fuel would do to your chances of passing a fuel check. We have had lawnmower gas in a plastic jug and reused it a week later for race gas and flunked tech immediately.
You will find C-11..."finickly". We ran it for years but every so often, always in super hot muggy conditions it will flunk. You always will know whos running it as on thoses days several of us would be standing around the scales, holding up the lines trying to get 11 to pass. It gets stale easily. Unless you really think your combo likes it (some do), I'd put 12 in it and be done with it ..
