Imagine my thrill as this last fill-up got 58 MPG plus change! Between that and the older, worse fill-ups dropping off due to being more than 90 days ago, my 90 day average lept to 54.17, and the % over EPA shot up to 54.77%.
And it even gets better; my last three tanks (maybe 4) were all over 55 MPG if memory serves, therefore, if nothing causes it to suddenly start getting bad, I'm going to hit 55 MPG average from just the older tanks dropping off. I think I've still got one or two in the high 40's diluting-down my average.
I love my 'gnat! - even though no one else I know does!!
