it wouldnt hurt and it wouldnt help. Pretty much diesel is diesel except for the dye in offroad diesel. It may have a little more oily substance,maybe lube up your injectors but thats it. I have ran it before i know a lot of guys that due. The only thing i can see is it cost more to have it delivered to the farm than on road diesel. Hopefully that answers your ?.
They usually dip your tank when your inside the livestock auction or at some agricultural event. Seen it happen when I was living in ND. If you do use it, make sure you stay away from places like. Fill up with road diesel as this will help dilute the dye and tell them it is an additive to the fuel if you get checked.
this is a great topic. there are very few things that GM will void warrantys instantly on. this is a BIG one. if anything fuel system related goes wrong and your truck is in the shop with off-road diesel, they will void your engine warranty on the spot. i have seen it several times. i come from a small farm/ranch town in Nebraska and the local dealership gets a truck or 2 in a week with off-road fuel. i don't know from personal experience, but a tech told me that the LLY has some o-rings in the fuel system that will expand and fail from the lubricants in the "red" diesel. be careful brother. and the DOT fines if you get caught are HUGE like $1000 in Nebraska.
That is all bs!! about smoking and seal damage, the older seals were made of copper(the new ones are made of viton I kind of prefer copper it doesn't crack or get brittle with age) dont know of any fuel that will damage copper. The red stuff is the same fuel just dyed for road tax purposes. But the fines and stuff are real if you get caught. I know guys been running the red stuff for years in their 6.2, duramaxes, even the powerstrokes . But most of these guys never leave the ranch with their work trucks so the are not breaking the law by driving on public roads much.
the red fuel is the exact same thing as regular disisel. The die is added at the loading arm.(i know this for a fact because i have built them) At present offroad is all the left over regular diesel, when thats used up it will be ulsd with red die.
It doesn't hurt a thing. 352,000 on dads Cummins running red fuel. Never a problem
all we ever run is farm fuel... or red diesel. The way i see it, diesel is a byproduct of gasoline, so some greedy white collar buisness man is making a crap load of money off of me and every one else driving a diesel. I have got caught twice runing the red fuel. Both times i had a tractor hooked up to me and i was able to get out of it by telling the state trooper, my truck has farm plates, i use it to work, and this is a agricultural based vehicle. i get tax breaks, and discounts for my fuel, vehicles, and the land itself for the animals , my feed, and so on, so why should i run street diesel when this truck is registered as a farm truck? I don't know how, but it's worked......so far.
