[BIGGPIGG4x4]

Hey Guys,
Buddy at work has an 2001 Dodge 2500 4x4 ESLB Manual, looking to get better MPGs, What should he do? Searched around the forum a little bit, and couldn't really find anything so I thought I start a post. His truck has a 4in exhaust on it that I know of. Other than that, pretty sure its stock.

Thanks in advance,

Pigg

A Programmer with timing will do the most. Beyond that you start spliting hairs. Rpms at 70mph is important also.

I would say some rv275's also and run the speed limit

Need as base to start at, what is he getting City? Highway/ What speed on highway? Tire size?

I regularly get 14 to 15 in the city and close to 20 on a long run empty.

He said he was getting 16+ mpgs highway. Wants a programmer but wants an economy and tow tune? What's best?

 

[BlackedOut02]

What gears dose he have?

From my experience: low rpm, low wind drag and high engine effiency = good mpg

Fuel economy is 85% driving style, 15% truck mods.

Powerpuck took me from 15-16 up to 18-19 just on 2 lane roads, dont do many highway trips 2 know what it gets over 65mph

Agreed.

You have to go easy on the loud pedal for the best mpg’s, not the most enjoyable way to drive but the cheapest. I’m averaging between 19.3 and 19.8 hand calculated with a mix of city and hwy driving and my truck is almost stock right now with no programmer…and I don’t drive like a grandpa so I think 20+ is definitely possible.

 

[BIGGPIGG4x4]

Not sure on gears. But he is a 60+ year old guy so I don't think he is too hard on the pedal.

Quick simple and inexpensive! Less than $200 from XPD.

Yup I can literally take it on and off in a minute! barrowed one before but never noticed milage increase but i thought what the heck I'll buy myself one and see if it does anything and it did well worth the money

i know that i only have a 2wd, but i have the edge comp ran on 4x2 with everything in my sig i see 22.6 driving city, hand calculated. arty018:

Driving style has a significant impact on fuel milege. I prefer manual shift so I can use progressive shifting. I normally grab a gear at 1500 rpm and spend a lot of time at 1200. If I'm loaded or pulling I'll keep it higher.

I've been working to improve the mileage of my 2001 2wd with HO engine 6spd (253K miles and counting) for a couple years now.

A GearVendor's Over/Under drive trani allows me to cruise at 1500 rpm and 70 mph. Also, have 4" exhaust from turbo back, HighRam intake and BigHead waste gate actuator. No tuner or electrical mods. I've kept the stock tires (Michelin 265/75/R16 ATS - which is a good highway tire, but terrible off road). I put snow tires on in the winter, and I lose 10-20% fuel mileage.

I also use Amsoil full synthetic products in the engine, GearVendor, Trani, and rearend.

All this gets me a consistant 23.5 mpg and sometimes 25. I also have a high rise cap on the back. Which helps, as I get 20-22 without it. Prior to the changes I got about 19. All numbers are all round driving (city and highway combined) At 650+miles per tank it hard to get a good city number.

I totally agree with wheelz I do the same thing...

I've kept the stock tires (Michelin 265/75/R16 ATS - which is a good highway tire, but terrible off road). I put snow tires on in the winter, and I lose 10-20% fuel mileage.

I run smaller and lighter tires than you do. 235/85 R16 on 16x7 aluminium mags weighing 62 pounds a piece. Yeah my winter tires are 85 pounds a piece and I lose about 2-3 MPG over it.

I also use Amsoil full synthetic products in the engine, GearVendor, Trani, and rearend.

Synthetics not required... I do the very same MPG's as you with petroluem oils.

I also have a high rise cap on the back.

I've got a aluminium topper on mine that weight less than 100 pounds.

Driving style has a significant impact on fuel milege.

So very true... Speed is the biggest killer... Going form 55 MPH to 65 MPH your wind drag doubles.
