I've uploaded a lot more mpg data here

I started taking notes about what kind of driving I was doing, where I refilled with fuel, what kind of fuel I filled with.
The avg OEM mpg is the average mpg I got on petrol, stock tires, stock everything except air filter. The avg e85 stg2 mpg is the average mpg I got on e85, stock tires, stock everything except air filter, OFH and OFT stg2 tune. The avg stg2 mpg is the same thing but on a 91oct tune.
