Just what we need...another MPG question!
Ok, probably a stupid question, but am about to $48K on a truck and want to try and under if this is an issue or not.
Want a new f250 bad!!! and trying to use improved mileage over a gasser to help rationalize the spend. I say rationalize because I can't really justify the diesel...really don't tow too much.
I've driven several and really want a CC Lariat (White w/ two tone tan and black interior is what I want the most). Found a great white twotone with an April build - 3.55 gears and 20" wheels.
When test driving, I was paying close attention to the fuel meter and was about what I expected...13/15 in traffic....getting up to 60 and setting cruise, seemed to have a hard time staying above 18. Good enough I guess, but then I test drove a different color and interior setup. Essentially same truck 3.55, but with 18" wheels.
When driving the truck w/ 18" wheels, the fuel gauge seemed to just climb faster and stay higher during the same test ride stretch.
The test ride was very short, though and the above was not done very scientifcally at all. Just trying to understand if mileage variance among the 6.7 is significant.
Should one expect two truck setup the same way to yeild the same mileage in the same conditions?
