dodge ram
 

01 4x4 sport qc sb 360 auto. Has shell or soft cover 265 75 16 tires no muffler 3 inch exaust modded tb cai New front 02 sensor. No data on sensor yet. Hughes plate superchip87 tune. Getting 10 ish to 11 ish mpg. Vac gauge and af gauge. Testing partial grill block and bumper block. Plans for the block elct fan. Took off evap lines to day to see what it'd do gained vac on gauge. Also 3.55 gears any more help would be great.

Gonna be tough getting any sort of decent mpg from that beast. Good luck.

Lose the CAI. Maybe some sort of aero cap.

Why loose the cai it got me 5 mpg back over stock with a drop in kn

Oh and aero cap could happen if it has a window and can haul and hung from

So you were getting 5-6 mpg before the CAI?

typically a CAI is for power while a WAI is for FE, cold air=power warm air=fuel economy. that's y he said to lose it but if u picked up 5mpg and your running over EPA standards don't touch it

Cold air is denser makes more power from better burn

Anything else? That I can do or change

I will suggest some high pressure touring tires and a front spoiler/ splitter that will help keep the airflow under your axles.

I just got new all terrain ties so that's out of the question and I use my truck as a truck was designed to be used no offense and I thought I didn't want assure under the truck plus I got the sport model

11 is about what my dad got out of his 99 w/ 5.9l, i could only get 16mpg burning a whole tank on a trip running about 60mph the whole time. from the rest of your comments i'm thinking look at the "100+ hypermiling tips" and maybe a scangauge, if you could get .5 mpg more with its help it would pay for itself in about 10,000miles since youre looking at 11mpg

my dad went from 11 to 16, driving the same way, the same routes, but with an '08 5.3L silverado

Iv read them and was using them and still getting ten mpg and mopar or no car

But I also don't have current data after the sensor change and disconnecting the evap

if the evap system is working properly it should be helping your mileage a little, and the electric fan(s) and grill block should help. i wouldnt think the cold air would help, but i hate how the stock air intake attaches to the tb worse, so i'd keep it anyway.

Does the chip run a lean cruise map? You won't get away with what a car can due to weight and drag, but you might still have some fat in your cruise mixture.

You could also pick up 1mpg by friction reduction treatment to engine and drivetrain - something like Militec-1 or Slick 50. Some oils help mpg too but careful not to go too thin.

I agree with you about cold air. Hot fuel is good for mpg though, but loses power in some cases - not always.

My thought in the evap IDs there's like4000 miles out crap drawing vacume he'll I'm pulling 20 inches at idel warmed up usually out pulls 15 to 18

Skid plates for aerodynamic improvement under the truck?
There's a guy on here (forgetting the name currently) that was using skid-plates - both aftermarket, and some home-made out of thin aluminum sheets, to improve the aerodynamic drag under his Cherokee, could help with the Ram as well... It won't be huge, and probably not as big as an aero-cap for the bed, but could gain you a little if you want to go through the time/effort.
If you make a type of belly pan following the lines a skid-plate would, you'd improve airflow without really cutting into your approach angle, etc. Not as effective as dropping it, but it would help while keeping it a truck. Looking at doing something similar to my Suburban when I get the chance... but I'm a new lurker here, too.

Any thing else

55 mph. Easy acceleration, drive with load, light anticipation...like someone mentioned previously "100 tips" should help where there biggest gains are to be had...driver skills.

I'm doing all of that neutral and easy driving I'm not going to turn three engine off tho because it's a auto what about h2o

Did you read through and understand all the 100+ tips and 65+ mods? People keep giving you pointers and you seem to be blowing them off. If you were actually "doing all that..." you'd probably be exceeding 11mpg, even with your truck. But you gotta put some effort into it, there's not just some easy gimmick to make a huge boost in fuel economy.

If you're unwilling to put some effort in it and you must be "mopar or no car"... buy a cheap 5-speed Neon and commute in that. Use the truck only when you need to do truck things.

20000miles 11mpg = 1818.2 gallons x $3.75 = $6818.25
20000miles 25mpg = 800 gallons x $3.75 = $3000
6818 - 3000 = $3818 = your new budget to find a car that gets 25mpg or better and pay for itself in 20000miles

I sold my 99 Dodge Ram Quad Cab (short bed) 4X4 last December. I consistently was able to get 15mpg out of it just by being smart about how I drove it. On straight highway trips I'd get 16.5mpg. I had a K&N drop-in filter (which was useless and a waste of money). I ran stock size AT tires (265X70X16) aired-up to about 48PSI. Just an FYI.

I have a 318 half ton auto dodge (just as big of a pig) and can top a little over 20mpg in the summer time with slow and carefull driving.

Your Dodge gets the best MPG with
1. No stops
2. With Quick Acceleration (approx 3/4 throttle) but not excessive accel if you will be stopping right away (conserve) momentum.
3. Driving steady around 35-45mph
4. Cost in neutral to about 8-10mph before stopping
5. Use standard stock size tires air to about 50psi.

If your tires are bigger than stock your odometer and speedo WILL be off, you will need to use this to determine your REAL FE. Also my dodge lost about 25% fuel economy with big tires.

Anyway Dodges your vintage always have bad intake gaskets ($50 fix +3-5mpg once fixed) and the transmissions electronics are always screwed up, also the rear pinion angles screw up and should be changed if they are near binding (this removes 33% of your power if they are wrong) Brake drag is also a big problem on 99-03 Dodges, align the thing, fix the intake free up the brakes as much as possible and set the driveshaft angles to the most fuel efficient position and post back here.

Other than that Dodge Autos are POOR for MPG, the transmissions have terrible shift points and are slushy and your idle speed is way higher than it should be. Your truck with an MT and 2WD would be 180degrees opposite on gas mileage. (15mpg summer without trying)
Might be worth 250-$500 in parts plus your time and effort to put in a 5sp stick.

Good Luck

Well done, Ryan. I used to have a 2001 V8-318 SLT ClubCab. No power and no mpg. Traded it for the bigger, heavier can-do-more-work 3/4T in sig. All your recommendations are spot on. I'd add changing over to the SPORT headlights with a Daniel Stern harness as well.

Glad to see another Mopar truck on here. Don't listen to the others about getting a different or second vehicle.

Depending on your skills/budget swapping to a manual trans will get you big gains.

If you go with an electric fan make sure you get a good and powerful one. My Dakota has a 16 and 2 12s on an all aluminum 3 core radiator and it still isn't enough in traffic on hot days.

Not sure what kind of capabilities your tuner has but you could play around with different settings on it and see what gains you can come up with.

The key to better fuel economy is sacrifice. You will need to sacrifice time, looks, speed or comforts. Sometimes big, sometimes small. Unless you are ready to do that you will probably not get more MPG out of that truck
