So, like I said in my other thread, I'm keeping this old beast. But with the high cost of diesel fuel, I'm sure fuel economy is weighing heavy on everybodies mind.
So lets start this thread to help each other out with fuel economy mods, and I will be the guinea pig (or however the heck you spell that). I have an $800 budget, but will only be spending that on items known to work.
So my first area of interest is tires. I am currently running 285/75/16 E tires, I like the size, but not the tire themselves, they throw rocks like crazy. But with fuel economy on my mind, I'm thinking a tire about the same height, but narrower would be a better idea, plus with a more street oriented tred. Any opinions on tire size/brand. I may not be doing this mod first, because it is spendy.
Second, air pressure in tires. Should one inflate to max air pressure to get the best fuel economy? I'm thinking yes, and I think I should air up my tires some more in the meantime.
Thirdly, Fuel mods. I'm thinking new/remain injectors and IP's would yield the best fuel economy, correct? I cant affoard an IP, but I have G code injectors, used, already. Do you suppose I would see a gain, if I had them tested, and remained if need be?
Fourth, Intercooler. I've heard that EGT's around 600* or less is optimal for fuel economy. Would an intercooler setup be worth it to lower EGT's to get better fuel economy? I wouldnt turn up the pump or anything, or adjust my boost, just put on an intercooler.
Fifth, Thermostate. Would a new thermostate, like the 203* stats that are sold for PSD's, help fuel economy? My truck runs around 190-200*, I've never seen it above that, even towing.
Sixth, Synthetic fluids. Is it worth it to swap over to synthetic fluids, I mean is the cost advantage there? Should I do all the fluids, motor, tranny, transfer case, diffs?
Seventh, Wind deflectors. Would it be a good idea to build up a wind defletor to go under the bumper, and go down to around the front diff area, kinda like the pre-runner trucks have. I'm thinking you would see a decrease is wind drag from all the stuff under there, therefore an increase in fuel milage.
Eighth, Gears. Should I swap to 3.08's? If I can do that, that is, in which case I should ask, is it possible to put 3.08's in my Dana 70 and Dana 44HD?
Ninth, filters. Should I put a bypass oil filter on, this might just save money in oil changes by extending the interval though...but thats still saving money.
Tenth, ZF-5 speed. Is it worth it to do this swap, if so what kind of increase am I looking at?
Eleventh, intake. Should I build up my own intake, or is the ATS intake good enough?
Lets get this ball rolling and figure some of them (the cheaper ones first ) out .
