I just installed some jammers stage 5 in my truck, but I am wondering is it bad to run red diesel in the truck now?

 

Man, you should have read the warranty on the jammer package. No red fuel should run through those injectors.

 

If you are off road where it is legal to run red, go for it. Your truck was designed to run on LSD which = current red. This new ULSD is too dry without some additive for lubricity.

Jammer 5's run smoky on any type of fuel, even nitromethane!
