I’m not sure how...but my latest fillup math revealed 16 mpg! I had to check it twice to be sure. I didn’t even spend much time on the freeway.
Im pretty sure its because the last fillup was ethanol free. Man its criminal that we are forced into that ethanol garbage when I just got 23% better mileage doing nothing but changing gas. Okay I also have the front driveshaft out still but when I did that before I didn’t register a legit change, in fact my last fillup before this one was regular e10 with the shaft out and I got 13.
I mean...16 is super poor still of course but I’m pretty happy. If this keeps up I could stand to save $200 a year even considering the higher cost of real gas.
