Diesel fuel grades

I have been getting conflicting reports about the difference between #1 diesel and #2 diesel. The book for my generator says to use #1,,,not sure what comes out of the pumps or what off-road diesel is. The local distributor here couldn't even come up with the answer. Just dont wanna mess up my back-up generator Thanx Ted

Re: Diesel fuel grades

The biggest difference that I know of is that #1 doesn't gell until a lot colder than it takes to gell #2 fuel.

says that #1 is used in stop & go applications, such as a generator might see. It also does make the fuel gell less, but it also has lower BTU value so the fuel economy is less.

Interesting comparison between grades of fuel: http://www.rxp.com/DieselFuel.htm

Re: Diesel fuel grades

#1 diesel is kerosene #2 is heating oil and on/off road diesel.
