I was checking the email, and this popped up, I found it pretty interesting.

I don't know what vehicle they were using for their tests, but it just is not true with my turck. I get 19.2 plus or minus, driving 75 to 85. I get only slightly better holding it at 65 to 70.

 

thats all it boils down to right there

 

Try installing one of these. lol

 

I agree, but I thought I would give people an actual way to save fuel, everyone b^tches and moans b/c their 6000lb truck doesnt get the mileage their 3500lb sedan gets. But I have to say is get over, cause I will be driving fast, and someone take a video as I go by please, I want to hear my new exhaust outside, Oh and patman do you really want that x-pipe??

 

so your saying if my truck goes on a diet and loses 3,500lbs it will get 25MPG?? hummm....wered i put my saws-allz??

 

I believe it - I get a LOT better mileage at slower highway speeds. I get 20+ if I keep it down to 65 or less, if I run 75 it drops down to around 17.

 

Me too, I just can't STAND getting my doors blown off, and it's all good till a nice lookin lady comes by, and then time to burn that fuel.

 

Ok! so what mods did you guys do to get such good gas mileage. I have a stock '01 F-150 4.6L and I'm lucky to get 14 mpg at 65 mph.

 

Thats about all you'll get rollie.

 

from what i have seen...

the smaller the motor the slower you have to go to get good mpg...

the 4.2 and 4.6 cant keep the truck moveing at high speeds like the 5.4..


like i feel that i get better mpg with the 5.4 then i did with my 4.6


Do a EcoBoost setup deal..

Turbo a 4.2 or 4.6 and run 3.2 gears or around there on stock tires.....

I dont see why the mpg wouldent be around 22-25 at 60-65

 

If you read the article, they mention this. It repeats itself for about 1/3 of the article.

"Engineers at Consumer Reports magazine tested this theory by driving a Toyota Camry sedan and a Mercury Mountaineer SUV at various set cruising speeds on a stretch of flat highway.'

 

My mods are in my sig rollie, and for everyone, on a nice flat road my 4.6L w/ 3.55's will get almost 23 mpg at 55-60 mph, but I can't ever run that slow on long trips. I can average about 20 rolling 70-75mph.

 

20!!! 23!!!

HOW, i have close to same mods as you, i know the visor cuts down or aerodynamics and the 285s are taller, you have little more engine. but i get 16 at best at 60. 14 at 80 at 2100rpms, if its not up hills...now on edge level 3 canned tunes no mods to tune.

im not calling BS, just would like to know how. it must be my flowmaster...

well i re-read your sig. much more than me but...you get a 7.5ish 0-60 with edge i get a 7.9...not to far behind. so we have reative power, i have a 3.55 and taller tires.

 

That was in the summer with 255/70/16's and nice flat driving. I can dogg my truck and get 14 on a bad tank, 16.5-17 with mostly city driving. I drive highway and get 19-20 driving anywhere from 75-80 mph keeping up with traffic. It gets ok mileage when I drive "sensible" which is rarely but at $3.50 for 93, I'm learning more and more to drive "nicely", thats pretty good for a 4x4 4.6L I think. I have heard of some with 5.4's getting 22 highway with 33's, so maybe you need a good tune up.
