I was just watching jeremy clarkson going from london to scotland and back on a tank of petrol and he said that the best speed for fuel economy in the audi he was driving was 56mph. I was just wondering if anyone knows the exact speed for best fuel economy in a mondeo 2.0l ghia x.
It was motorways all the way.

When I bought this truck new, diesel was a lot cheaper $1.60, now its topping $4.00. What upgrades would help fuel economy, new intake, new computer chip or tuner, exhaust etc? I use this truck everyday 50-60 miles normal driving and a couple times a month I do have to pull some equipment 8,500lbs. Right now I’m only seeing about 11-14 miles per gallon and any improvement would help.

I have been looking at the 2008 Ford SuperDuty F250. The dealer sticker and sales man are reluctant to give any fuel economy numbers. Does anyone have any realistic ideas?
I am looking at the Diesel motor… Standard in the F250 series..

Im looking to buy a local f250 here in texas that i can use as a daily driver. Its a manual ****** and has 39.5 inch mudders. Would fuel economy **** on this kind of setup? I will be driving about 1.2k miles a month. Thanks for any input
What if the mud tires were replaced for some smaller ones, would my MPG’s be better?
