2004 5.4L F250 mpg and how gears tires etc affect
Okay.. first I apologize if I have posted something that has already been answered.. I hate when people do that so I searched hard, but haven’t found my answer... this forum and the guys posting here are full of info.. awesome.
I am looking at buying a 2004 F250 5.4L V8 3.73 lmt slip FX4. But.. full after market conversion package.. lift kit oversized tires.. etc..
I am very concerned about mpg as I put on 15-20k / year.. but can’t own anything but a ford truck… I believe the 5.4L will get me the best mileage over the V10. I don't want a diesel.
So… this truck that has 4” suspension lift and 305s rather than the stock LT235… 31.7” to 32.8”
This forum has tons of info.. based on a different thread went here:
looks like my 3.73 gear is now 3.6 this affect towing.. which is fine.. I tow a 3000# ski boat occasionally… no issue.
but.. the bigger tires throw off the speedo based on that site above also.. so I need to calculate the mpg differently based on traveling farther than my odometer indicates.. but the lower gear ration gets me better gas mileage right??
I guess my real question is what gas mileage I can expect. Either based on above details and expectations… or if someone out there has a similar truck and experience.
not sure if it makes much difference.. but the truck is a super crew, short box, 4speed Auto transimission
Thanks for any help...
