Here is my "Baker Black Brew mix" or bunker fuel oil mix:

Late summer 2006 - present,

80% pump diesel.
18% Chevron Dello 400 diesel crank case oil (Used, out of my Cummins powered truck)
2% Amsoil cetane booster
This is mixed 5 parts to one part of Davis plane diesel giving about 6% ether. That is 6 gallons of Baker Black Brew for every 1 gallon of Davis used.



I have flown 7 - 8 gallons in my OS 40 LA with a Davis head and a 12 x 6 MAS. It hand starts but needs choking till warm. It gives about 3 minuets of flight time per oz. on a Big Stick .40. It idles very nicely.

I have also flown it on a .061 paw but it is hard to start without a starter.

I have also flown it without any Davis fuel as an etherless mix but it needs warm weather and is hard to start.

Thanks goes to Andy Woitowicz for his inspiration and the the cetane booster idea!

Treven Baker.
