What's the deal with these LLY's? My buddy, who I finally got to convert from the Ford camp, can't believe his MPG's. On a full tank my LB7 will give me 670Kms. His gets 512Kms at best. We have the same size tank and I know for a fact that he is much softer on the go pedal than I am. Any thought's? Oh, he has a little over 6000K on the truck now too so I'm sure shes broken in by now. Right? Nick

300 miles on a 26 gallon tank? How much weight is he towing?

Honestly he has about 200Lbs of tools in the box at all times. I don't think that would make too much of a diff, would it? I wouldn't believe it either if I didn't see his trip reading all the time.

One thing is that the gauges are more accurate and linear on the LLY. When you both fill up are you both putting the same amount of liters in? I have no problem getting 650km's to a tank on my LLY.


The other thing is the two of you might have different driving styles.


Your truck is also broken in and his is not. Lots of variables.
