Biggest mpg increase for the money

[mrdontplay]

First of all, hello everybody I'm the new guy.

I have a 2001 4x4 crew cab long bed 1 ton and I was wondering what upgrade can get me the a decent fuel milage increase for not a lot of money. I don't really drive it as often as my other whips(20000 miles sense 05) so I need something that will pay for itself quick. Any ides?

at roughly 6k miles per year, not much will pay for itself anywhere near quick unless fuel prices go way up again.

Will a K&N drop in filter do anything noticable for power or MPG?

[JakeLewis79]

It will help hp, but I don't know if it will help the "seat of the pants" acceleration. It will marginally help mpg, but not significantly enough to notice. For mpg, some of the things you can do are: front end alignment, lower rolling resistance tires, "free spin" manual hubs, Gear Vendor Overdrive, and just don't be heavy on the go-pedal. The November 2008 issue of Four Wheeler Magazine did a write up of most of what I listed. Hope this helps.

the other thing you could do is make the truck breathe better. open up the exhaust by just taking out the muffler or replace with a full 4" system. also do an air intake system or the DIY tymar intake. that will help some. if you combine the above with a reflashed PCM from Dp tuner that will help some more. Jody has a 80 economy setting that helps.

Do not use the K&N drop in filters, they have dusted many a powerstroke!!! The best mod for mpg is FREE, it's called tire pressure!!! Next you need to let the engine breathe!! You don't need a 4" system, just replace the factory muffler with a Walker BTM, and do a DIY Tymar intake. This will help quite a bit.
Congrats on the new truck!!
wELCOME TO THE org!!

using a synthetic oil will give you a little better mileage, and it'll start nicer.

and change your fuel filters if you haven't done it for a while! dirty fuel filters really suck away your mpgs.

I don't think there's some really big change in efficiency you can do to make you mileage jump more than in your right foot

The difference between WOT and the old "egg on the accelerator" approach yields dramatic changes for me...... (I just can't stand to drive that way! )

I installed a 57 series k+n intake gained noticable power but lost 4 mpg's.
