I have an unconfirmed, yet in my opinion, a reliable story, from a friend about another friend of his that runs a construction site where everything runs on red diesel.

This guy apparently bought a brand new 2003 GMC Sierra 3500 and about 2 months later loaded it up with red diesel. Supposedly the engine turned over just fine, but when he put it into gear it shut down on him.

This guy was friends with the person who runs the GM dealership and called in about it, letting him know what he did.

The story is that there is a sensor in at least as early as the 2003 Duramax that checks for the red dye and locks up the fuel pump.

Resetting the pump was not something that could be done at the dealership, but the pump needed to be sent to GM to be reset, which in itself cost $2000.

I've had another person looking into this and said that the sensor does not exist.

I personally have no intentions of running red diesel in my vehicle, but was posting to see if I could confirm the existence of such as sensor in the fuel pump and other's experiences with it if it does truly exist.

It's BS...:D

it'll run fine....altho I don't know why I know..):h

mine is an 05 not an 03 but i've ran the so called "offroad diesel" in my truck a time or two and have had not problems.

I can't find it - but someone posted a GM bulletin here that stated that dealers should treat red-dyed fuel the same as on-road fuel when it comes to service issues - in other words, don't say that any issue is the fault of the fuel; and that they are to continue with diagnosis and repair as usual if "offroad fuel" is used.

We use something called 'purinox' .It looks like pepto bismol. It is for off road vehicles. It contains a lot of water and has ruined an injector pump or two on very expensive fork lifts. We use it on just a few units, kind of an EPA thing. Slowly phasing it out as it seperates and clogs filters etc. As far as the red dye thing, total BS in my opinion.

No doubt about it.....this is a BS story! :blahblah:

bs, gm says red fuel is fine. Only caution they give is contaminats as it tends to be stored in less then desireable ways.

I Don't Belive It, I Do It All The Time Including Kero With No Problems

This truck has ('05) has only ever had red fuel in it. My previous '04 lly went 35000miles with red dye and no problems at all. Know someone with an '02 that has 80k or more miles on it all on red dye and no problems.

THAT WAS BS!!!

Even if there would be such a sensor which there OBVIOUSLY isn't, how would people run red dye (those that are allowed to...like me)

I have been told that if you ever have used red "off road" fuel in your vehicle that they can tell forever if you ever get sampled. I know that some people have the reason run red, but this would be few. Just letting you know I have heard they can hold your truck if they find the smallest trace and fine very heavy.

:sleep:

My truck is no stranger to the red. I have never been able to tell a difference in the two fuels. They actually are the same fuel one just has an added dye. Stop listening to the rumor mills. Read here first!!! :blahblah:

This topic is so old it could vote.

Tell your friend to just put some blue food coloring in his fuel, that way the "Red Dye" sensor will be fooled and he'll be OK.

Lets see now are all the folks that are burning red fuel expected to admit their sin?
Just put some green dye in it that ought to fool'em.

You can always argue that you used to only drive it on the farm. They have no way of proving otherwise. Or the "officer, I was stranded and a farmer lent me some fuel" routine. The list of explanations is endless.

LOL...that's all I have to say.

mmmmmm*cough*mmmmmm

FooFog - You are not Foo Real. So beware posting future fooish posts!

I ran red in my Kodiak with a duramax 03, for a year and had no problems, have been running off road clear for a year in my 04.5 with no problems. Diesel is Diesel, but no BIO diesel. A Friend who owns a Fuel injection shop told me to stay away from biodiesel because they dont have it perfected yet, it emulsifies with water and ruins pumps.

During the fuel shortage in florida after the hurricane the EPA lifted the restriction on Red fuel for like two weeks to be used in over road vehicles. That tells me there is no difference and tells me they can't detect the small amount that says you used it in the past. Otherwise that stunt would void all future tests.
