The problem is getting the fuel out of snowblower WITHOUT running it. It is not easy to do thus the fuelstablier and running the blower for 10mins with fuel line cut offWe did that for years at the College then we learned from Terpstras that it is better to do this
Dump out most of the fuel and run it until it stops. there is no fuel to gum up during storage. it also saves you the cost of the Stabil.
