Fuel Mileage for 3500 1 Ton

I just bought a 1988 3500 truck 1 ton.It has an automatic,4:10 gears and a 350 engine,4x2,50,000 miles on it.I use it to pull my rock crawler.I got 10 mpg ,so I installed a K&N filter,removed the exhaust and installed headers, flowmaster mufflers and 2 1/2 pipe out the back.I still get 10mpg.Any ideas on what else i might look at.I do not know if a chip or gear change might help.What I tow weights about 3000#.Thanks Ranger Rick[[email protected]]

Re: Fuel Mileage for 3500 1 Ton

<font face="Comic Sans MS">Running synthetic fluids in the engine, tranny and diff should help you pick up at least one mpg... [img]/wwwthreads_images/icons/crazy.gif[/img] What RPM does the engine run at while you're at highway speed? Do you hammer the throttle away from lights, etc? What height tires do you run? That could help effect it. Is the 3000# the Zuk only or does that including whatever trailer/tow dolly setup you have also? Is it flat towed or trailered? Might look at the bearings in the trailer or dolly wheels if you have one, repack the bearings... [img]/wwwthreads_images/icons/crazy.gif[/img] Just a few thoughts... Seems like you should be getting better than 10 mpg since you have no t-case to eat any power... Brakes dragging? </font>

Don't beat yourself up to bad about gas mileage ,10 is not really that bad for that truck.That truck is heavey and has a lot of rolling resistance.

Re: Fuel Mileage for 3500 1 Ton

I normally get 12-13 with mine empty, but pulling the horse trailer it drops conciderably since my foots usually barred trying to keep my speeds up for the hills, so 10 doesnt sound that bad to me. Ive never checked mine enough to know what it gets towing but Ill bet Im down to 10 or below.
