A modified version of Ed's Red using John Deere Low-Viscosity Hy-Gard ATF, MEK, kerosene, mineral spirits, toluene or xylene, some Lube Control LC-20, and about 1.5 oz. of Lucas Synthetic Oil Stabilizer per quart (I have a bunch of it on-hand and it does seem to help with lubricity).
The only drawback is that this mixture doesn't have a flight number associated with it
