Off road Diesel versus #2 home heating oil

[radioman]

I am getting conflicting information on #2 fuel oil (heating oil) versus off road Diesel fuel. The Driver that delivered our last load of heating Oil told me you can no longer Use #2 heating oil in a Diesel engine because they have removed all the Cetane from it.
We have a couple of 275 gal tanks at our place that feed the oil burner and I would love to be able to tap off of those to fill my John Deere 850 on occasion. Diesel burns fine in the oil burner, and if the price were comparable why not fill the tanks with Off road Diesel? What say you?

Hmmm . if cetane was removed ,, it wouldnt combust right? therefore your furnace wouldnt be "burning it" ?

Google Cetane for additional information.

Cetane keeps Diesel from preignition when injected. It is like the OCtane for gasoline.

That is incorrect.

This is the definition from about .com
Similar to the octane number rating that is applied to gasoline to rate its ignition stability, cetane number is the rating assigned to diesel fuel to rate its combustion quality. While gasoline's octane number signifies its ability to resist auto-ignition (also referred to as pre-ignition, knocking, pinging, or detonation), diesel's cetane number is a measure of the fuel's delay of ignition time (the amount of time between the injection of fuel into the combustion chamber and the actual start of combustion of the fuel charge).

Because diesels rely on compression ignition (no spark), the fuel must be able to auto-ignite--and generally, the quicker the better. A higher cetane number means a shorter ignition delay time and more complete combustion of the fuel charge in the combustion chamber. This, of course, translates into a smoother running, better performing engine with more power and fewer harmful emissions.

When our heating oil is delivered it comes from the same batch as the farm diesel . Truck pumps 1500 gal into the farm diesel tank then 500gal into the house as he leaves !

I'm in Rhode Island. When I call up my local fuel oil supplier and ask him to fill my fuel oil tank, I get an invoice that says diesel on it.

Then, you are very likely heating your house with ultra low sulpher diesel. Not heating oil.

I dont know but i only had oil heating for 18 years and it's always been that way... just dyed farm diesel .

Same thing here.
#2 is heating oil. We use three different distributors, and all of them do the same thing. Shop oil tank gets filled, bulk tanks get filled.
Same stuff getting sold to the folks in the city that burn oil.

ULSD heating oil? Whatever.
