A further note as stated above. At least 15-20 crop spraying fixed wing pilots I know personally use Illuminating Paraffin full time i.e. 5-6 hrs per day since I have known them. They have never suffered any ill effects related to the use thereof as long as the normal precautions of transporting, storage,pumps etc are adhered to. They have no build up of sediment in the FCU's or any part of the engine, no problem with restarts or hot starts, no temp problems, no unusual exhaust smoke etc etc.
I do not know their insurance rammifications or there proposed life span and before you say "obviously short" - I could not agree with you more than "only use recommended fuel". I was interested though in the area of any OFFICIAL testing that anyone did know of.
Thanx again and safe flying....Big Boy.
