Here is how you calculate:

Start with a full tank (Topped off), then drive to your destination. Then top off again. Divide miles driven by the amount of gallons you just filled.

Just use the receipt.

That is the only way to tell EXACTLY how much you had driven.

 

My best ever was 14.6 mpg, and that was babying it.

 

thats how i calculated it. So I know its right. I also had my tires up at max too.

 

in the summer highway driving i might come close to 18 mpg.thats with stock tires on my '96 4x4 5.2 litre regular cab.i run all synthetic fluids,k+n filter and never drive it hard.i beleive my tank is about 120-130 litres to fill,and the longest range i can possibly get is 850 to 900 km.in the winter city and rural driving i bottom out real bad.about 550 km per tank.

 

I can believe it personally, altitude has a ****load to do with it.

 

i have the same mpg's with my truck, but no one believes me... (18 highway, and 14 city)

 

I can believe it. Especially highway miles. But most of us here are looking at out city and highway mix of MPG. Average MPG.

I averaged 16 MPG in my 1996. Weird thing was that it was worse on the highway. Mainly because i drive pretty fast and don't like to lose speed up hills.

 

I get around 18-19 highway on the parkway cruising at 70mph between here and Tampa. This is with a 2wd 318 regular cab short bed. Calculated the same way as offroadjosh.

 

I get about 9 city 12 highway. Then again I always spin em every red light too. Needa stop that; trannies gonna blow (or my rear end, still havn't checked my fluid in there since i bought it)'

would having my front diff locked in also increase it? my vaccumm accuator is broken.

 

hahahah best iv ever gotten is 11 LMFAO ....... damn 4.88's
