Where I get my offroad diesel ,on the pump it says it has a high sulfer content, could this give me problem or is it normal for offroad diesel to have this?
Some people on this forum think the sulfur is needed for injector pump lubrication. Think it's a bunch of bunk. The sulfur certainly won't do any harm other than give a stinkier exhaust and gunk up your oil a bit more than lower sulfur.
JD says only run low Sulphur content fuel, but I doubt you'll find anything different. The process that removes the sulphur also strips some of the lubricity from the fuel. I'd recommend a good additive in all fuel like FPPF Total Power.
