Is it true that red dyed diesel has a higher sulphur content than your average fillup stations diesel?I run it in the '93 sometimes when I need fuel(don't tell anyone)but I have never noticed any difference.Does it lubricate the pump better?Of course you can always run the additives but I was just wondering about it.

In the old days it was higher sulphur.

Now it's the exact same thing as regular #2 Diesel, with the chemical dye signifying no road tax.

Bad mojo running that fuel on the road, and saying you do in a public forum.

Men in Black will be knocking at your door shortly.

I know the red dyed farm fuel around here is just that red dyed fuel. The fuel dealer puts the dye in when he gets the fuel.

What I've never been able to figure out is why you can buy tax free farm fuel in 10,000 gallon loads and it's your choice if it's dyed or not.

Around here farm, heating and road fuel are identical except for the colour.......I have even received heating fuel that wasn't even dyed once.....don't know how that happened and the truck driver didn't elaborate, all I know was that I didn't have the means to pump any fuel out of the tank!

Pre-1995 there was a difference. It was high sulphur. No longer. The EPA made sure of that. I use 1000 gals a month on the farm and sometimes it's dyed and other times not. Either way, I've not had an increase since January, because of my bulk contract.

One of our shop guys used to run a hot shot service, He was pulled over running off road diesel that wasn't died. The officer added a chemical to the sample and after a few seconds, it changed colors. There has to be another additive in off road diesel thats not in taxed.
Altho, he didn't mention when this was, it might have been pre-95

There are both high and low sulfur off road fuels available today. Your areas may only carry one, but both are in existence. Check what you're buying if you're going to use it.

I misss the days of red fuel. In 97 and 98 we were getting it for .49 cents a gallon.

Dang! Moving to the big city has its drawbacks.

I don't run it on the road.I use it here on the place as a ranch truck.So they can come lookin' for me if they want!

A neighbour of ours swears that the dye will mess with your fuel system and buys clear diesel and just pays the tax, burns it in his tractors.

I know some of the sophistaicated super high pressure injection systems have issues with the dyed fuel.

Like our J.D 9320, the filter will actualy filter out the dye and bung.......

infidel

Hard to believe that on the dye plugging the filter, when they add it it's like a half gallon per 10,000.

Since I work for the state all our diesels can legally run offroad fuel and they always do, never a problem even on '05s.

There were some problems back in the day.
The farm diesel, being higher sulphur, made some rubber seals and lines in the fuel system swell.

When you went back to regular Diesel, they would shrink back down causing leaks.

That isn't the case anymore, as the both are the same fuel (supposedely).

Hand of God the filter would be plugged with dye!

But that is super fine flitration and wicked high fuel pressures on those things..


You don't want to bust it, that's a 1/4 million $+ tractor.

and it is filtering a lot of fuel!

I have burnt 250 gallons PER DAY in that thing. Scary.

BP for one offers both high sulfur off road (5000ppm max) and low sulfur on road (500ppm). As most have found, low sulfur dyed is more commonly found - however high sulfur does exist. I saw a high sulfur offroad pump a month ago.
