I would not consider kero for a road going engine as the pressures are to high for adequate lubrication of not just the pump but the injectors, bear in mind the needle in the injector is a very precise machined element, it takes around 2000 psi to lift the needle from its seat with virtually no leakage past the needle in its bore, running on poor lubricating kero will accelerate wear on this important high temperature component leading to its early failure, Rick
Isn't kerosene heating oil? I think it Could work ok, not neat - but at the ratio stinka says, blended with 30% veg for the lube. The problem as far as I can tell, their is no amount of kerosene that can be used as road fuel in the UK, by law. Not even 1ml. I don't think you can even pay duty on it if you wanted to be above board.
Different countries have different laws.
