Using dyed diesel in a pickup truck

Shimon · Jun 1, 2006

( If the dye changes the color and stains the filter does it make it harder to check for other fuel problems? Like if it sits for a while fuel gets darker doesn't it? )

Well, a lot of road vehicles and boats used dyed fuel and it doesn't affect fuel diagnosis problems. Usually when the fuel gets old and the asphaltene seperates out you can tell because it looks like a black tar-like substance. The filter media gets dyed right away from the fuel but it's not a problem.

Not worth the risk in my opinion for .60 a gallon. I have seen the DPS staked out at the sale barns around here punching tanks for dyed fuel. Don't know how the "Katrina Relief" fuel thing will affect that operation. But I do know (not from personal experience, of course!) that it takes SEVERAL tanks to get it all out.
I remember some years ago at a DOT check some local log haulers were "detained" while the red substance in their tanks was verified to be ATF. Hassle factor alone makes it risky.

JUST CURIOUS, is the dyed diesel really higher in sulfur or do they put that on there to deter people from wanting to use it? Would a higher or lower sulfur content affect the engine in any negative way?

Starting in September, and sooner in some parts of the country, all you will be able to get is ULSD diesel, dyed or un-dyed. All the myths and misinformation about sulphur in the fuel goes right out the window.

This has been discussed to death in the Fuel/Lubrication forum.

Pure and simple off road fuel does NOT in any way shape or form stain or dye your fuel system in the slightest. Once it goes through your tank CONTRARY to urban legend they would not know if you had red fuel or not. All they go by is what is in your tank right now. They dip the tank and if it is red you have a problem. If it isn't red you have no problem at all. They don't go pulling filters and fuel lines. /forums/images/graemlins/crazy.gif
