I had to change the EPA for my car because I had put the wrong numbers in. How long does it take to reflect in the percentage above EPA? I notice it takes a little time to update in the graph when inputting a new fillup...I'm wondering if the sig percentage calculation is the same deal. It's still going off the old 24MPG combined, instead of the new 26MPG combined that I put in. (24*1.171 = 28.1)....(26*1.171=30.45) So, the percentage should be 8.1% above EPA.

I am assuming the percentage is based on the amount your last 90 days is over the EPA combined rating...am I correct? Or, is it the percentage that your last 3 fills are over the EPA combined?
