I find 27-30 hard to believe. I guess because everyone I know that has one of these trucks gets between 15-20 mpg.

How many km are you racking up per tank?

 

15-20 mpg in a 12 Valve?? Was it loaded right to the max or whats goin on?

In our 92 250 CTD. Driving pure highway, not a km over 100 down the 401 back and forth to Toronto we have gotten just under 33mpg.

Ive never gone under a quarter of a tank in my truck.

I forget how many kms I went last time and how many litres it took. But next fill up Ill tell ya. But that will be with my cetane booster, so It might change a bit from before.

 

Must be those imperial gallons...

 

What is the difference there, I think there is 4 Litres to the US Gallon and 5 Litres to the Imperial right? I am not very sure though

 

1 USGALLON = 3.78 LITERS
1 UKGALLON = 4.54 LITERS

You must be calc. by UKGALLONS, because if you are calc. by US gallons, you have to be running close to 800 miles per tank to be getting 27mpg.
