RE: do i need to change fuel?
Hi!
In Europe it's very common to use 10-15% all synthetic oil with 5-10% nitro for all glow engines (except small COX engines).
The syntethic oils we use are: Aerosynth or Aerosave by Fuchs (German company) and Motul "Micro" by French company.
In the US, Klotz is a very common brand .
Thechniplate (synthetic) or Benol (Castor oil) are the name of their oils.
