I have a 2001 f150 4x4 5.4 V8 and was wondering if i put 33X12.50X17 nitto mud grapplers what kind of MPGs I would get? or if yall have any other suggestions let me know. thanks

 

I have the 5.4 engine, 3.55 gears and 35 inch BFG AT KO's and I get 13 mpg. I did not have my speedometer/odometer corrected when I had 33 inch AT KO's but the best I could figure was around 14 mpg.

 

I've got the 5.4 liter also with 35's, the EDGE programmer, K&N CAI and Magna Flow True Duals. I just changed my oil and fuel filter a couple of weeks ago and with this last tank of gas, I averaged 16.5 miles while running the EDGE on level 2.

Pretty happy about that all things considered.

 

I get about 13 when doing only in town driving and 16 to 17 on the interstate

 

w00t! V6 getting 19 mpg city

 

i burn about 16L /100km on average which translates ironically to 16 MPG. i guess that's where the curves meet.

 

thanks for the relies! any sugestions about what to do to improve MPGs i have my truck compleatly stock and am only gettin 11 and its starting to put a dent in my savings! and 11 is what i was planing to get what i am getting now when i put the new MTs

 

I'm getting around 18-19 interstate on my 4.6 with 33's and 18's...i'd add an intake and exhaust for starters..then maybe a programmer

 

Get a K&N drop in filter.. $50. Or get an exhaust set up, which will make it sound nice and get better mpg's. A programmer will definitely change things. Better spark plugs and wires or a upgraded mass air flow sensor. There are alot of things.. the list goes on.

 

A K&N dropin will not make one bit of difference. The BIGGEST difference is remove the lead from your right boot.

 

Very true GLC lol, expecially in a bigger v8 they are thirsty to start with. other maintenance could help to if its nearing the mileage mark where required or just at the point of needing attention example: Fuel Filter, Air Filter, Plugs(coil,wires,COP's), maintained air pressures, balanced tires, wheel alignments, etc. Just basic routine stuff that gets pushed off or overlooked when it comes to mileage.

 

GaNole07 what nitto tires do you have? mud graps or terra graps

 

The terra graps had them on my 2wd that was totaled woulda probably got mud terrains if i knew i was gonna get a 4wd

 

A new program will help. Putting the stock tires back on will help. Keeping the tires at max inflation will help. Lowering it will help. Light foot will help like others said.
