Mark,

I use the Stanadyne Performance Formula in the "warmer" weather, but in Northern NH, when it gets down to -20 F, my fuel gels, so during the dead of winter I use Power Service and my fuel never gels. The power service bottle says it contains no alcohol. I know people on this site do not like PS and GM does not have it on there recomended list, so whay an I susposed to use in really really cold weather? As for mixing kero, there is not many places that sell it.
