the only time ill run stabil every tank is in my chainsaw because it rarely gets used ,other than that outboards ,snowmobiles,atvs,seadoos, lawnmowers etc only get stabil when there done there season and heading away for a few months or more,NOW during use I do add carbon guard by OMC and every engine gets a can of Engine tuner thru it ,same as Sea Foam but by OMC,adding stabil every time ya fuel up ,well looks like im gonna buy some shares in that stock this afternoon
