I have an oil burning boiler with a separate tank for hot water. I also have about 6 gallons or so of kerosene for a backup heater that I'd like to change out, as well as a little diesel fuel conditioner, also a gallon or so of new lube oil for a diesel I no longer have. My plan it to burn it in the oil burning boiler, substantially diluted by the usual fuel oil. I'm thinking I'd be fine. Opinions?
