GT 10 speed MPG's

Wondering what your average mpg's are in your 10 speed auto GT's. Normal/Average driving highway and average city. Looking for info on the GT PP as well as the base GT's mpg's. Thanks in advance. I did try searching but didn't find much. I also know that you don't buy a GT for the MPG's ....

I have a 2018 Mustang GT with the 10R80 and just over 2500 miles since last June. So far a average MPG of 20.5 to 24. I have a heavy right foot. I have the 3.55 rear gear ratio.

Computer in the dashboard tells me it's 20.1 overall since new in July, 1848.4 miles of "break-in"-style driving. Received wisdom is to discount the displayed MPG by about 13%. I've been too lazy to break out local and highway travel, or even to do the fill-miles-fill-calculation. First car in my history I've not done that.

Well - I'm not normal I guess... I drive in sport mode when the roads are dry - I also put the transmission in sport, it holds high rpms longer.... I'm addicted to the downshift rev matching ....


in the end - I'm averaging after 5k miles, 17.5 MPG... I don't really care about the MPG - I put in VP racing 92 octane non-ethanol gas every time.

Good to know it doesn't cost as much as a viper to drive in fun mode
