I do not have one that I'm aware of.

I'm thinking, sometime in the next three months, of trying at least three tanks back-to-back of premium (93 octane in Michigan). Running at least three should account for the remaining regular that is left in the tank/fuel system on the first tank of premium, like you mentioned, as well as give me a good average. The only way I would stick with running the premium is if I find that it's cost effective; i.e. the mileage increase, if any, makes up for the additional ~$2.20 spent on premium over regular. If not I can always try midgrade.

I'll keep everyone posted.
