Having read most of the posts in this section, it seems the most popular method for keeping BD from gelling is to either add 20-30% petro diesel or kerosene to the mix. I heard from someone that the "Heet" (did I spell it right?) fuel additive can work. Any thoughts on that? I don't suppose ethanol could work, could it?

I just bought a 1986 vw golf in great condition to run BD on. It never smoked at all when starting it up on regular diesel, and right now I think I have about 60% BD in it, and noticed that it smoked for a few minutes yesterday morning (our first frost of the season). Is that bad for the car, or indicative of something?

HEET is Methanol. ISO-HEET is Isopropanol (Rubbing Alcohol).
1 cup of HEET to 15 gallons of fuel won't do a whole heck of a lot other than helping to soak up a little moisture... and perhaps prevent water-ice from forming in fuel lines.

If you are making your own biodiesel, generic methanol is the same as HEET.

There are reports of manufacturers testing Ethanol/Diesel blends in their vehicles. E85 certainly would be cheaper than little bottles of HEET.

The problem with alcohols is that they tend to suspend soaps and glycerin during the manufacturing stage of biodiesel. I suppose that wouldn't be a big problem to add in a later stage.

Many solvents will work with blending. You might also consider regular gasoline (RUG).
