Ok I had the stock gears replaced with 410's and I have a Edge CS programmer. Is there anything I need to do to let the computer kow that the gears are changed? also, is there a programmer that allows you to chane the gears and tire size for the F350 7.3 diesel.

I also will be traveling from NJ to Arizona in two weeks...is there away to increase the MPG? also what is the difference between the Off road and standard diesel? I understand that I can get fined if I get caught...but really how often will I get pulled over. I have a reserve tank in the bed and will have the cap on so noone will be able to see it.

so if I keep alittle more then quarter tank of standard diesel will it be noticeable?

 

i couldn't tell you what to do with the programmer and your new gear ratio. i think the best way to increase your MPG is trying to keep RPM's lower. find that good cruise speed, maybe even draft behind an 18 wheeler... i know getting your truck as close to stock is possible is the best way to achieve premium MPG (too late for that though). as for the diesel blends, i'm guessing you mean farm or agricultural use diesel when you say 'off-road' diesel? i know its got a dye in it. NW ohio had red dye.. i think it's cheaper and in some cases you'll have to show paperwork. its been a long time since i've seen farm fuel. i'm not even sure you'll be able to get 'off-road' fuel along your road trip...
as for getting caught? me, i wouldn't do it. not worth it. i hate getting pulled over. been pulled over twice my entire life. once for window tinting in nowhere AK and once in high school when my buddy had his butt out the window mooning folks at the rest stop. i TRY to follow the rules now.

 

The money that you would save by running off- road diesel is not worth the fines that could come if caught IMO.

 

ok I just had to ask......

 

the offroad diesel has a dye in it.IF you get checked, they will stick your tank or tanks....real hefty fine but I have never heard of anyone around here (north Ga) checking or being checked..You will have to change the fuel filter more often as well..

 

Farm fuel is dyed either red, or a blue-ish tint depending on the state (others out there generall RED).

As for running it? I saw a HUGE concrete company go under in about 7 hours, for running off road fuel in there cement haulers. DOT was doing a check point, and either A) running a little dipper down into the tank or B) pulling fuel filters. Checking the filters on these 7.3's takes about as long to pop the hood and unscrew the cap, and they WILL do this. On some trucks, running off road fuel makes them smoke substantially more (roll this dark black coal colored smoke) and is almost an instant sign for any trooper, not saying this is the case in the 7.3 just some motors (we run it in our 7.3's with farm plates not really a noticeable difference in smoke).

HOWEVER

IF YOU GET CAUGHT YOU ARE DONE, AND BY DONE I MEAN D-U-N DONE!!!!

In ohio its something like a over a HUNDRED THOUSAND dollar fine, automatic truck impound with zero chance of getting it back and almost certainly a permanent loss of license and or prison time. Oh and did i mention the the 6 digit fine? The risk isnt worth saving a dollar per gallon (we get our bulk farm fuel usually 1.45 cheaper depending on the amount and its contracted so doesnt fluctuate). Some states its more harsh, some less, but in the end the pros DO not outweigh the cons in terms of risk.

 

Changing the filter does not work, if they still suspect it, they will dip the tank, where the dye will linger for a long time.

edit- I only know this because my old 6.0 had farm plates for awhile, and re-registering it i had to get documentation that this was indeed a farm truck thus ran off-the-road diesel fuel.

Im not 100% sure but the tank-dip-swab thing can determine amounts or something judging on color now, kind of like a PH strip to determine whether its just a trace amount (ie just the dye lingering) or a full tank of off road diesel.
