Hello
I agree with needsenginerunning.
Kerosene is formulated for good flowability and wickability, not lubricity. Unless the pump/injectors are designed for this they will prematurly wear.
Last winter I disposed of a 275 gallon tank of 15 year old stove oil (is like a low grade kerosene: no lubricity, excellant cold weather nongelling, and thin enough to gravity flow through an oil stove carburator) by mixing it first 20/1 with old chain saw 2 cycle mix oil. Most was burnt up in a neighbors oil furnace which has a high pressure delivery pump and a fixed orifice injector system that is designed for #2 diesel/furnace oil. I had promised to replace any damaged parts and pay service costs.
Ran out of the old 2 cycle mix and tried mixing new ATF. Took about a 20/1 to 30/1 to get the same percieved lubrcity as #2 diesel. Some brands of ATF were too prone to foaming when mixed.
Finished it up with modern 50/1 2 cycle oil mixed at a 30/1 ratio.
His furnace performed fine. My J.D./Yanmar tractor ran fine too except on some of the ATF mix would foam out the fuel tank from the injector return flow.
Both aplications had near full outputs, no smoking or coking build ups.
Saved me $2750. USD in registered disposal costs. Saved the neighbor appx. $750.USD on his annual heating oil bill.
