Chevy43,

How cool an engine can get and still run well was looked at a while back on this thread. It appeared, at least on the Norvels, that running cool, even on diesel, isn't that much of a problem. That is, with the fuels I was trying. You have a truly unique mix and I commend you for giving it a go.

At the moment, I'm downloading, on to Google Video, a clip where I fly the dieselized, Norvel .074 in the winter, on my MiniSport on skis. On stock, 40/40/20 fuel, I had no trouble starting and no adjustments were needed from a start. As you'll see, start the engine and just go fly, very much like glow. But again, on a high ether mix. The temperature was just a few degrees above freezing.

I just got a kit for getting raw vegetable oil to run with the addition of a 'secret' ingredient along with kero, gasoline, a diesel additive and the ingredient they sell. Will give that a go and see what happens. I got 22 ounces of the stuff and that's supposed to treat some 132 gallons. Yes, this was intended for the big stuff. Samples are available free for anyone interested.

The formula they suggest for one gallon+ of fuel goes like this.

1 gallon vegetable oil. Fresh or waste.
12.8 ounces of kerosene
6.4 ounces of unleaded gas
.7 ounces of Power Services additive. This is an anti-gel, cetane booster. Do WE need that??? Dunno. I'm going to try the Amsoil cetane booster.
.15 ounces of the DSE or Diesel Secret Ingredient.

The .7 ounces can be stated as 20cc, the .15 ounces as 4.5cc

Diesel Secret Ingredient, (DSE) is trashed on some Biodiesel websites but of course, you have to view that sideways, as this stuff competes with Biodiesel in that no treatment is required except good filtering along with water removal. All of this is done by simply pumping your waste oil through some filters and then adding the other ingredients. Not labour or energy intensive except for the pumps. And even then, a guy could use a hand pump.

For us, we'd just use a cheap veggie oil off the shelf with no need for filtering, I presume.

I ordered it on impulse, you never know, it might work in our engines by simply adding their mix, 80% along with 20% oil, castor or otherwise.

Looks like it'll take all night for the video to load to Google. Will provide a link tomorrow.
