What destroys injectors?

Long story: My truck almost ran out of fuel the other night. We filled it up with red fuel b/c we were in the field and that was all i had. There might have been water in that fuel but the light didn't come on. I have been running Power Serives Cetane Booster for the last 20K miles. Anyway after filling it back up, it still ran bad. Changed the fuel filter, blew out the fuel lines. Took it to the shop, they siphoned the tank, still ran bad. Turns out had 2 bad injectors. Put 2 reman ones in. Still ran bad. They ran computer test, 2 more bad ones. What do you think did it? It's getting expensive. Thanks.

I wouldn't think farm fuel would do it, it's the same exact stuff as road diesel, just dyed so when the tank is dipped it can be noticed that you didn't pay road taxes for it.

Sulfur is your injectors friend. It has excellent lubricating properties. EPA just wants it removed because it is a pollutant. I think it comes out as sulfur dioxide.

I wouldn't think it still would, with all the emission standards coming forth, and I suppose it depends on the diesel you get, regular or premium. But for one tank full to ruin injectors that quickly, I think that doesn't make sense. Are you able to tell by the injectors what made them go bad??
The guy that I bought my truck from ran nothing but farm diesel in his truck, 127k on it now and haven't had a single problem with it.

The farm diesel will not ruin your injectors by itself. But if it was contaminated , now thats a different story. You might have sucked up some crud from the bottom of your tank, and ran that through the injectors when you ran your tank dry.

Same here.....


It seems like the most logical explanation.

Unless air got into the system and while the engine was trying to purge it, it hurt itself. I know what I just said probably doesn't make sense grammatically, but think about it.

next time you drain your tank that you got the fuel out of, try taking a flashlight and looking in it and see if you notice anything in there. Or maybe even just pump some into a large glass or plastic container and see if anything settles on the bottom. How old is the tank that the fuel came out of?
