Re: tanks full or empty for premix fuel?
I'm in the camp of NOT leaving gas in the tank over winter storage for these reasons: 1-can't do gas any good to sit there for months and it will not improve as fine wine does. 2- condensation and the chance of getting water in the tank. 3- another reason, kind of in the "nervous Neally" camp, is the issue of on adding fuel to a fire, especially with a rig witha 100 gal tank. 4-In my case, I trailer my rig 550 miles to the lake in the spring so why make the trip with all that weight? I put the TW-3 oil in at home and fill'er up near the lake.<br /><br />At the end of the season, here's what I do: On my last boating trips of the year I try to run my tank down less that 5 gallons. Then at home in the driveway, I put Stabil in the tank and run the engine on the muffs and disconect the fuel line and run the carbs dry and fog the engine through the carb as it runs out of gas. (I also do all the other winterizing stuff) Then I syphon the gas out of the built in tank into a 5 gal gas tank and store the gas in the can for use next year. I make sure the can is air tight. I then tape the built-in tanks vent with duct tape to minimize air entry.<br /><br />Then next year I put a 1/2 gal. of the stored gas back in the tank and resyphon it back out into a clear container to see if there is any water or other stuff got into the tank. I think this is a good way to keep crud out the tank.<br /><br />This may be over kill but I figure better safe than sorry.<br /><br />StillFishin'
