Same reason I didn't choose higher priced premium gasoline. The price is between the two and the performance/efficiency of the fuel should be between the two. I didn't even use the reformulated price, which I should have because almost every company has their own blend of additives, which falls into the reformulated category if I'm reading that correctly.
But the Ecoboost gas engine that were are talking aboutis a variable grade fuel engine and the owners manual recommends regular 87 octane for advertised power levels. Premium is only used if you want higher then advertised power level and performance.
So again, why are you using mid-grade fuel prices and not regular fuel prices?
Taking for granted the fact that people use that higher grade fuel to obtain those numbers on fuelly? Does Fuelly break that down? Give me the average mpg for the lowest/cheapest gasoline then and I'll plug that info in the spreadsheet.
Back with my Chevy, I got significantly lower fuel mileage when I put the cheapest stuff in. I only ran premium a couple of times, but never used the cheapest stuff if I could help it.
