Andy with the hight AI temps of Naptha I don't see how it willl be helpfull. I found gasoline not to be helpfull because of the high AI.

It still looks like the cheapest most readily availible low AI fuel is kerosene.

I have had such good success with pump diesel that I'm excited to try kerosene. Since I flew on eitherless pump diesel I should try it with kerosene and see how much better it is.

Also it really isn't that expensive to run 5% either. One can of JD starer fluid in 1 gallon will give about 5% either + whatever ignition improvers JD puts in there.

I think a really good mix willl be:

74% Kerosene or 94.4 OZ $3.71

19% oil or 24 OZ $FREE

5% (app.) can of JD either 7 OZ $3.71

2% Amsoil CB or 2.6 OZ $1.66

This mix should run great considering it runs pretty darn good using pump diesel so the kerosene should make it that much better.

Total cost for a gallon $8.66 (CALIFORNIA PRICES ) Easy to make and easy to get the stuff.

For small engines ,if nessasary, it would be easy to put in another can of JD either.

Treven.
