RE: Synthetic oils soluble in methanol besides klotz?
Synthetic jet turbine oils such as BP2380 and Aeroshell are miscible (capable of being mixed; specifically : capable of mixing in any ratio without separation of two phases)...and are widely available at airports. These are not cheap however. If you can find any Poly-Alkylated glycols such as used to be available from Union Carbide...these were excellent oils for glow engines. Klotz has been used successfully for many years in glow fuels and work well. Several of the popular glow fuels use Klotz as the main lubricant. Years ago I tried several synthetic car and motorcycle oils such as Mobil 1 and Amsoil. These will not mix with methanol. From the standpoint of cost and availability, my advice is to use Klotz.
