#1 is actually kerosene, which is very low in natural lubricity properties, and is typically only used to blend with #2 during cold weather to prevent fuel gelling

#1 is high sulfer diesel for off road use only. Atleast in Va, that is. It is also dyed so when VDOT checks a tank on a big rig they know immediatly. It is also non-taxed here.

Okay, then thats the crap in my generator. But here in Cali we still run the ULSD in the gens but it is dyed. Same for farm equipment I believe.

#1 has less BTUs and is drier as mentioned.

My understanding is that #1 diesel and K-1 Kerosene are related, but not the same. They sure don't smell the same. K-1 smells like kerosense and Diesel #1 smells like diesel. #1 DF will also probably have a higher sulfur content.

Probably correct since Cali has the smog laws. It is probably not taxed and labeled for off road use only, correct?

MGLICK, #1 is a better grade than #2. I know in gasoline the 93 has less BTU's than 87 but has a lower flash point. Hence the motor runs cooler. This being the reason I run 93 in any aircooled engine. I'm not sure if this holds true for diesels or not.

I know people who have run Kero in their trucks and said it actually ran better. Very expensive but better than running out if no diesel is available.
This was an older diesel and doubt how well it would run in today's motors (LMM, LBZ, LLY but could probably run in LB7)
