Kerosene?

[JLDickmon]

Kerosene is bad since it is missing lubricity that has already been diminished from regular diesel fuel. Sure you can run it for a while but who knows when problems will arise due to low lubricity of the fuel.

hey yeah I didn't think of that...
he'd need to add a cetane booster and a quart of two-stroke oil to each tank...

so given this, is it still cheaper?
