C11 and C12 in fuel check

[Mike Pearson]

I have never had C-12 fail fuel check even if it was left in the cell for several months. I did run C-11 for a time but didnt have a good source for it. I also tried Sunoco but always seemed to have difficulties at fuel check with the Sunoco Blue fuel. I didn't see any difference between C-12 and C-11 except in my wallet.
