Coking in Arriels.
Is there any documented evidence that Prist reduces coking in Arriel engines?Apart from the anti-freeze capabilities it is supposed to prevent coking and act as a bacteriacide agent. All this , along with the 30 second cool down also achieving the same, is all hearsay. It would be nice to get some written proof.
My DO does not believe that Prist is required in helicopter fuels(go figure--but the man is a Fixed Winger -can't blame him for his misspent youth) and is planning on doing away with Prist in bulk fuel purchased by the company. Apart from the fact that the RFM for the Astar calls for mandatory Prist when temps. drop below 0 degree C. a reinforcement argument, at least for Astars, would be nice.Anyone?
