Well Lie-O-Meter is behaving the same average per it is 47.8mpg ave on this mix and I am in my in town cold weather mode so I expect it to drop further, trouble is my father also drove the car (-3mpg on a 150 mile tank) and its getting cold which takes off 5 to 10mpg on this car easily.
This is actually doing "well" considering the amount of higher speed driving and town driving was done in colder weather. I will know when I eventually fill up if this mix paid off, was a wash (I lean to that choice) or cost more $$$
I chose the mix based on the fact that it cost the same price as plain e10 but had much higher octane, it appears the octane on a 2.2ltr 10.5:1 compression ratio car wins out over the additional ethanol in the tank.
The ethanol MASSIVELY affects my acceleration FE during warmup, bleh 9mpg instead of 18mpg sucks.
Ah well
