Kerosene

Can kerosene be used in diesel engines?

I doubt it, especially the newer motors with all the DPF and electronics. Kero is at least $1 per gallon higher in price than diesel.

It's what my company uses for anti gel in the winter time. I never need it, because I was lucky enough to be able to park inside for most of winter this past year in the customers maintenance garage. So not sure how much was added per tank.

I don't mean for a truck. I have a Gehl skid-steer with a Duetz 4 cly. engine and have some free kerosene available. I know there are a lot of TT members who are more knowledgeable about diesel engines then I am.

My dad with 30+ plus years of diesel experience says it is fine.

A Diesel engine will run on kerosene. It will run on jet fuel as well. The problems with kerosene and jet fuel are the same. Since they are both more refined, they burn hotter. So the engine will run hotter as well. Also since they are more refined, they do not lubricate as well. This leads to increased component wear inside the engine. They do however, burn cleaner leading to less pollutants released from incomplete combustion.

FYI, the military uses Jet Fuel in all of their diesel vehicles. The type of fuel they use is JP-8 (Jet Propellent type 8)

The USN used JP-5 for my entire career.

JP-4 and JP-5 are even more refined than JP-8. So... the downside is more noticeable. JP-4 and JP-5 are really hard on rubber gaskets and even the braided fuel lines. They eat them up. But on the upside, the more refined the fuel, the more energy released from and the more complete the combustion. Also the more refined a fuel is, the lighter it is.

We used JP-5 exclusively in Naval aviation, both at sea and on land, due to the lower flashpoint. It had nothing to do with fuel cells or fuel lines and O-rings.

Thanks for the info. I think I will mix one gallon of kerosene into 4 gallons of off-road diesel. Does that sound reasonable?

(The jp-4 I need to reserve for my Lear jet. Money is getting tight.)
