The bottom line is run the power service. I have never in the 30 years of driving diesels had one gel on me. I buy fuel from 1 vendor and when I don't I add power service. It also adds lubricity to the fuel, granted the newer injection systems are designed to run on the "dry" fuel but it can't hurt. I don't worry about it in the summer, maybe every 20 tank or so just to keep the algae down. When I worked for a oilfield hotshot company we had trucks jell when the drivers filled at filling stations [we had a 15000 gallon tank at our location] We would pull the fuel filters off and fill them 1/2 way up with 911powerservice and added the rest of the quart to the tank and that normally got the truck going. If not then the pick up was gelled/froze and you had to heat the tank. Not fun at 30 below zero. Powerservice is cheap insurance for me. CJ
