Very bad for the environment and engine. Engine oil has additives specifically for suppressing its combustion.

Kerosene
I have not tried this, but I will unless some veteran advises against it. But, a few years ago a long haul trucker I know said in winter he adds kerosene to his fuel to keep it thin. I will start lean, maybe 1 gallon per tank full.

Kerosene reduces lubricity and #1 diesel is already winterized. Unless you're driving from Texas to Minnesota on one tank of fuel in the middle of winter, #1 diesel doesn't need any additional anti-gel.

Diesel does not need any additives as long as you use #1 in the winter months to prevent gelling. Neither #1 or #2 needs any help in lubricity. ULSD became the only on-road fuel sold since 2006 (no matter the pump label), if there was a problem with it there would have been a sudden mass of pump failures within the first 2 years.
The fact we are nearly 5 years into it with 99% of the worlds diesels using straight diesel from the pump means the entire "lubricity" issue was, from the start, purely a myth to sell useless snake oil off the shelves. Just as it was in the early 90's with LSD.

LSD??? your supposed to melt that on your tongue, not put it in your tank. and never drive on LSD anyway; its kinda scary the way the steering wheel stretches all out of shape when your trying to turn.

LMAO...I think he's refering to LOW SULFUR DIESEL.
