To be on the safe side always run high sulfur diesel in the older equipment and when you can't for example because you have to run undyed fuel for on road use, use a fuel additive to restore lubricity. That's especially important when your engine's injection pump relies on the fuel itself for lubrication.
Even with injection pumps with their own lube oil supply lines, using low sulpur diesel has resulted in expensive pump failures. As low suphur diesel gets phased in over the next few years a lot of folks are going to be forking over dollars to their local fuel injection pump rebuilder.

I only use high cetane low sulfur BP Supreme On-Road #2 diesel in our four tractors as well as our two turbodiesel motorcars.
Seeing that you have a Kubota 3130, that is what I would suggest is best for you too.
If your diesel engine is over 25 years old and has >5,000 hours on it, you might want to stick with high sulfur #2 simply because the fuel injection pumps prior to the 1990's used weaker O-ring material and are prone to leakage with modern fuels due to dehyrdration of the O-rings.

Early 1990's, I think.

I always try to run dyed off-road, either way I add some power service ( white jug) and a splash of marvel mystery oil to every jug of fuel I buy. I have found the engine/pump is quiter with the addetives than without, I only have 300 hrs on my bx but I figure a little extra lube never hurt. /forums/images/graemlins/smirk.gif

I run the dyed off-road diesel from the local BP station in my TC40. I can tell a difference in the smell and the exhaust when using the off road stuff compared to the yellow diesel that is sold for road use around here. Its wierd, but I think it smells better when running the off-road stuff. Probably it is just fond reminders of my father-in-laws old MF and John Deere equipment. Regardless I put some additives in that is sold my my NH dealer. Given how little the TC-40 uses in terms of fuel, the cost of the additives is more than reasonable.

Putting the red dye in the yellow fuel don't change a thing.
If you put red food coloring in a glass of water it's still the same glass of water.

I really would not expect dye to do anything to make a smell. Typically the red dyed stuff has more sulfur since it is off road and does not have to meet the EPA requirements for road use. I guess I did not explain it clear enough that I knew it was the higher sulfur content not dye contributing to the different smell.

I don't know about Ohio but for most of the midwest and the west they don't even sell off-road high sulfur anymore. Most all of the fuel sold is the same thing as you buy from the pump. The dye has nothing to do with EPA requirements at all. That I know for fact all across the US. All the dye does is mark it so that if the DOT dips your tanks and you are on-road you will get a fine. You can run red dye fuel on road if you can show that you pay the tax.
Also if you have an older truck or tractor just add the power service or other additive that contains lubricants. You will get a 100x the lubrication as the high sulfur diesel and not have to deal with the soot of the high sulfur diesel.
