Aviation jet fuel is a refined diesel fuel, and I've been told that there isn't any top end lubricating properties associated with it. I have access to large quantities of waste jet fuel. If I were to mix it 50/50 with pump diesel, would I get enough top end lubrication? If I were to use 100% jet fuel and added, let's say, 16 oz. of Marvel Mystery oil for every 20 gallons of fuel, would that be sufficient enough top end lubrication? This fuel will be burned in a 1980 300D, non-turbocharged vehicle (110K). Thanks for your opinion in advance!
