Diesel Question ?

The problem with adding anything to diesel fuel on the 1995 and up diesel is that it may really screw with a number of things. Tighter machine clearances are a problem if lubricity is lost. Adding gasoline will kill the lubricity.

It'll also drop the cetane rating, meaning you'll need more heat to fire the mixture. Once its running, thats not a problem. But on very cold start up, you may see a problem.

I have a pdf of an independent test of diesel fuel additives that are commonly available and the resulting lubricity factors. If there is interest, I'll attempt to post it here.

One thing you'll find is that lower sulfur fuel has less lubricity. One of the cheap and easy additives that adds lubricity is... 2 cycle oil.
