and I mean real world numbers,
I know no matter what level this Edge of mine is on it does not improve mileage much, if any, over stock.
I do have a Banks , straight through monster muffler and a K&N filter. I hated the whistle with the AFE intake so i went with just a K&N.
One guy swears 3 MPG with a Diablo, 60HP tuner.???
thanx guys, crossy

 

Keep your tires aired up

 

Use the SEARCH function and search K&N filters.

 

drive slower **** it!
my pops says many big rig drivers are keeping it around 55-60 to conserve nowadays


and like he said, aired up tires is big!

 

• I found max air pressure in the Michelins made a big difference, but for some reason it's not as important on the BFGs, seems like 55psi gives me the best return on mpgs for whatever reason. So many factors though it's hard to tell for sure.
  
• Also keep your filters clean (air and fuel). You will be disowned from the CTD brotherhood if you install a K&N, be warned.
  
• I may have seen a slight improvement in mpg's using the Power Service additive in the silver bottle. Enough to justify the extra cost? Probably not.
  
• I leave my EZ on level 2, hard to say if it actually improved mileage but the overhead seems to think so.
  
• I think I took a slight hit on hwy mpg when my front air dam went MIA, and possibly again when I added the mopar bug deflector. Again, I don't have any solid evidence of this (aren't I helpful?)

 

I noticed a difference when my muffler fell off and put on my BHAF air filter. I now have the ****** whistler intake.

 

Slow starts, don't goose it to get to speed and plan your stops, coast down. Lower the speed on the highway. I've always heard to keep the rpm's below 2000 but even a little lower say 1600-1700 has given me my best. I have a Smarty, run it on 3 or 5 and do what I've mentioned. Also, one post talked about aired tires, yep, absolutely right along with clean filters. No one thing will be the magic bullet but a lot of little things will add up somewhat. Bottom line, you are driving a big truck and you aren't gonna get Volkswagen Diesel Bug mpg's no matter what you do.

Also, in my opinion, don't be fooled by a lot of the reports about fantastic mpg's. If I used my computer only and didn't figure actual mpg's, I'd be telling everybody I saw 22 mpg's last tank. I did but it wasn't real. Also, I have a buddy who fills up and as an example he put 11 gallons in and ran 220 miles but to him that's 10 gallons and 200 miles so he got 20 mpg's. As I said, there are a lot of pie in the sky reports out there.

 

Taller tires help a little, just so you can get the lower rpm. My AFE helped a tad but not very much. The biggest factor is not racing the little ricers on the highway, its so hard to resist though.

 

No tuner is going to give you 3 MPG. All advice given here is good, but there is no magic to make the truck get that 3-5 MPG increase. Drive slower, properly inflated tires, drop the front end of the truck, keep the RPMs below 2000. And I guess I'll be the first to say it, keep a close eye on that K&N. Have personally had a guy at work denied warranty work because of the K&N air filter, and after 6 months K&N would not help him in his case against Ford.

 

that K&N will ruin your motor i have first hand experience with it, we are running 12 dodge ctd's an average of 1,000 miles a week each, all pull heavy and a lot of it is 2x cgvwr , i started last year to see what i could do to increase mileage while towing with out hurting life of truck, we have a pile of junk four foot high we tried and did not work or we found other things that worked better. the mods shown in my signature was the ones that we are adding to other trucks .this truck with cgvw of 21,000 lb at 60-65 mph started out at 9.0 mpg now at 14.6mpg the smarty jr gave the most for the least money some of the mods worked but will never pay back the cost

 

i've got a 2 mpg increase putting on the quad mileage max module. i have not changed my driving habits and this is hand calculated average of two tanks.

 

Other than buying a used Honda civic (which is what I did) for commuting, I don't think there is anything you can realistically and cost effectively do to these trucks to increase mileage more than 1 or 2 mpg. As everyone else has said, keep tires aired up and filters clean. I use the truck when needed. Civic gets 35 mpg and is easy to resell later.

 

I've thought about that too, but the time a find a cheap car,insure it,plates,fuel, it would take to many years to recover the $$, plus I'd be paying on a museum piece to sit in my garage, and the pain and suffering of an accident with my family in a ricer just to save a few bucks is not worth it,but your results may differ.When I have this truck paid off in two years, I might park it too, and buy a more economical car though, but not too small.

 

A lot of people disparage the K&N product, but extensive testing has shown them to stop even the smallest pebbles.

 

Perhaps...But the oil misting from the filter element contaminates mass air flow sensors. Seen it on F150's and VW diesels. I'll never run another K&N. They are great on carb'd motors though.
