n/m............

 

I have 3inch body lift and 6 inch suspension and I run 37 inch tires on my 1995 351W F-150 with the 5 speed manual. I get 10Mpg so you probably could get 13 out of that.

 

Yeah it could have been a misprint. But I would probably be tempted to throw the 35's on there!

 

i dont see how a tonneau cover has anything to do with it looking like a van but alright..but they do look better on a stock suspension truck, just a suggestion. but with those tires and that much lift its realling going to hurt the mileage on that truck. 13 is possible but most people with stock tires and suspension are getting around 15mpg at best

 

You would get 13mpg only if you keep your foot out of it and do a lot of hiway driving, expect 11-12mpg mostly.................Sorry, Lying goes against the grain.

 

probably not going to happen.

 

Well Thanks! I appreciate everyone's honest (and not so honest)replies. Heres a round on me.

 

With 3.55s, 3.73s, or even 4.10s, it all depends on how well the truck is running and how you are going to drive it. The '94 F250 in my signature has 32s and consistently gets 13 to 14 (straight highway) with 4.10s and it does not even have overdrive. The kicker is, I have to drive 55 to get that mileage. Hopefully the truck has 4.10s, with a 351 and 32s, 4.10 is the ideal gear ratio in my opinion.

Considering that my friends '94 F150 with a 4 inch lift and 32s sat about the same height as my F250 does stock, this truck should be about 2 inches taller than mine. That 2 inches of extra height should not make a huge difference.

I think, no matter which of the 3 mentioned ratios you are running (if higher than 3.55 or lower than 4.10, your mileage will suffer), the truck should be able to get 13 (straight highway), provided two conditions are met.
1) The motor is in good shape and tuned up good. If you get it: do an ignition tune up, change the fuel filter, check for vacuum leaks, check for a bad cat, pull the codes, and fix any problems that might be mentioned. Below is a link to a site that will tell you how to check the codes without a reader.
2) Don't drive like a madman! If you drive over 70 mph you do not have a chance in hell of getting 13 or better. Try driving between 55 and 65 mph. Find the fastest possible speed that gets you acceptable mileage and stick with it.

Good luck!

 

You have allready been lied to,tonneau cover does nothing for MPG.

 

what does the MPG matter?? if your getting a fullsize truck with a 351 and a 6in lift on it, your sure as **** not getting it for the gas mileage! lol

 

does everyone have there speedo adjusted for their tires, or atleast taking that into consideration. with larger tires, you get less rev per hour than the stock tire that the speedo is caliberated for. so when you drive 100 miles, your trip may say 90. (just an ex) so it will look lke you are getting worse mpg's than actuality. but i agree, if you drive a full size, lifted truck, with loud pipes and tires, you dont really give a hoot about mpg's. atleast i sure dont and all my buddies dont really either.

 

Thats waht I needed to hear! I am student living at home so all I need leftover is money for beer, bait and ammo...

 

actually, they do.

i have used one and left it off and guess what?

mpg was higher with it on.

do research before you try to state an untrue fact.

 

he probably watched that show mythbusters had on-about the tailgate up or down e.t.c I honestly believe different results for different people
we all do what works for our own needs
