Fuel check question

You know it's volatile stuff when we've generated a habit of holding our hand over the cup while waiting in the fuel check line.

And for those that didn't read the Atlanta thread, beware purchasing any 112 octane blue VP at your local bracket track. It's not on the approved fuels list, and it doesn't check as anything. The southeast VP rep said it is something they formulated that's "close" to Sunoco Blue, but a little different in this spec or that, and they just sell it to the bracket tracks. Why have a readily available fuel and not have it on the list?

We've had the opposite effect. I have not had good luck with Sunoco checking in recent years. I have bought from tracks and sealed drums. Each time I take Sunoco to fuel check it is a problem. I have had great luck with VP C-12. After laying in the sand at Atco last year in 90 degree weather draining the sunoco and wasting gallons of C-12 trying to flush the system I think I 'm just going to stay with VP for now. For the amount of bracket racing I do...I would love to just run Sunoco at the cheaper price, but I don't want to switch the car back each time I want to race stock. Has anyone else had issues getting Sunoco purple or Blue to pass?
