I have a toyo kerosene heater that I'm going to be removing and replacing with a Reni propane heater(both are like a monitor direct vent heater)
I have a small twenty gallon stainless tank outside that feeds it.
I'm guessing it has ten gallons of kerosene in it.
My question is can I run that in my kubota without any issues?
Or mix it 50/50 with diesel.

No one here who regularly works on Kubota tractors is going to say you can safely run that fuel.

My manual states No 1D S15 fuel for temps under 14F. Me I would
mix it.

No1D and kerosene is the same.

#1 Diesel and Kerosene are not the same.
They are similar, but there is mutiple additives (lubrication) that are missing.
Running Kerosene can cause damage to the injection pump and injectors.
It also has a much lower flash point that can cause Piston and ring issues.
If it detonates early it can damage just about anything.

It's risky to use Kerosene any diesel engine.

It is marketing.


You may have heard kerosene and “Diesel #1” used interchangeably. While they’re not exactly the same thing, they are similar enough that the terms often overlap. Diesel #1 is a product with a lower density and flash point than #2, among other differences. Technically, kerosene is governed by ASTM D3699, while diesel #1 is governed by the same spec (ASTM D975) that regulates “normal” diesel. A gallon of fuel could meet both kerosene and diesel #1 requirements, but the standards for #1 diesel are a bit less stringent than those for kerosene. Either way, you’re likely to hear about “kero blends” during the winter; even though it’s more likely you’re receiving diesel #1, either will work.

Older diesels do great with a mix of #2 and Kero when it's really cold. It's your choice, but I'd not run it straight in anything.
