A common question most likely with different answers... I have 4 cycle 48" Bobcat Hydro along with Simplicity Snow King, Walk behind Leaf Vacs. Also I have several 2 cycle pieces of equipment (Back Packs and String Trimmers). All year round I use fuel Stabil in Fuel in all 4 cycle equipment. Question: What are the suggestions for the 4 month winter season of non-use. I do drain all 2 cycle so question is for 4 cycle equipment. Also is is it OK to change the oil at start of mowing season? a: Leave fuel in Gas tank with Stabil and turn fuel shut off "off". Also run the engine till out of fuel? b: Empty Fuel in tank and engine by running till dry? Totally dry for 4 months (May dry out Gas Line?) c: Leave Fuel with Stabil in Gas tank and do not run the engine dry? One owners manual suggests c: Not sure why? Thanks!
