Hello,
I don't have a diesel model engine yet. I do work for an F.B.O. at the local airport. We sell jet-A with or with-out prist. Jet-a is aviation grade kerosene. The only difference between jet-A and K-1 or Kerosene that you get from the filling station is it is supposed to be handled more carefully to prevent contamination.
Prist is an additive that caused moisture to be suspended in the fuel, rather than settling out. This prevents microbial growth and ice in the fuel filters.
We can sell avgas or jet fuel to anyone with a proper container, however there is no "road tax" on the fuel, so we can't sell it for use in automobiles. Some F.B.O.s wont sell it to anyone who doesn't have an airplane, company policy.
The trucks and underground tanks are "sumped" regularly, You might get some for free.
I am considering converting an A.S.P. .46 if Davis Diesel makes a head for it. I want to use this engine in a 3D Giles 202 ARF. The kit recommends a .40 2c or .52 4c. What do you think? The engine runs great on glow. Will I still get good throttle response and reliability, with more power than glow?
