The price is a few cents less per gallon and sports a higher octane. I get less mpg with the ethanol blend which I think is typical. I guess its a choice of better mpg with straight gas or a vote for less dependence on oil with ethanol blend.
Also, I tried Mobil 1 which carries a $20 premium per oil change. I noticed no difference in mileage. I'm back to regular oil.
Mileage: 45 city about the same on the highway.

Is your car in the database? It won't suddenly improve your MPG but it will give you an idea of how well you're doing.
What model? How many miles? How long have you had it?
I agree with you about the Mobil 1. I'm headed towards a synthetic for longer oil change intervals. I've finished up about 5k on my Mobil 1 but I'm planning to go a whole year on the next change (not Mobil 1) with an oil sample test after 6 months.
Are you using the MFD for MPG or odometer/gas receipts? Just curious.
Thanks,
