I don't like MPG's I like MPD's

As long as the price of gas is going down my miles per dollars keep's going up

 

Same here, I have an 02 with the 4.6 and 92K. I get 14.6 mpg mixed driving consistantly.

 

I have increased mileage about 10% highway and local by adding 1 ounce of pure acetone to 10 gallons of gas. Also have found it costs about 10% in mileage using gas with ethonol. My 07 is getting 14/15, 18/19 highway, have a k&n filter otherwise stock, I have a heavy foot .. Also use Mobile 1.

 

i hear that using acetone is hell on the rubber lines and such?

 

i see 11.5-12.5 all city with traffic, and 14.5-15 mixed
