I would like to start using 91+ auto gas in my CTLSi, for all the obvious reasons. Mechanic at my field said it's no problem, even with ethanol, as long as it doesn't sit in the tanks too long. He then suggested that I filter the gas with chamois cloth before using it. I tried this yesterday--lined a funnel with chamois and poured from one jerrycan into another. The problem is it took forever--the gas flows at such a trickle that it would have taken me an hour, literally, just to fill a single five-gallon can. Obviously not a viable solution.
My questions:
1. Is it really necessary to filter auto gas?
2. If so, is there a better way to do it?
Thanks for any advice.
