I got started with Power Service 20 years ago and use it as directed on the bottle and if it really gets cold (-35 F) I put Power service Red in also, but I have also gone to using blended Diesel fuel when I can get it and two places here in Laramie WY have it but that is only when I read the weather forecast correctly. I have only gelled up 3 times in the last20 years and last month was the last time and I had not put blended fuel in it so Power Service RED saved the day.
