Anyway, the "octane rating" is based on the performance of a motor fuels as compared to isooctane (100) versus normal heptane (0), and it's a measure of how quickly the fuel-air mixture will combust.
Cetane rating is essentially the time-delay from injection to ignition of the fuel-air mixture. Cetane-improver is unnecessary for a diesel designed to run on 40 cetane.
Adding motor oil to diesel fuel is unwise, since all the components don't burn; ashless 2-cycle oil is OK, but I use FPPF or CRC additives rather than 2-cycle oil.
Adding gasoline is also not just unwise but dangerous. The diesel-gaso mixture will now have the flash/fire point of gaso - and damage to the engine is quite possible (ever notice the prohibition against using ether to start a glow-plug equipped engine?). The gaso will also defeat the addition of lubricating additves to the diesel.
It is a common mistake to confuse off road (500ppm) diesel with Home heating oil they are very different with respect to sulfer and lubricating properties Which result in a higher BTU per Gal than on and off road fuel which are identical to each other except for the red dye for tax purposes.Just take a piece of clean wood and spill an ounce of each and see which one is still there after a couple of hours. As far as supporting my attny maybe we all better put the cats back on and yank the ecm's out before the boogie man gets us
