[EC900]

There’s a Sta-Bil 360 for ethanol not labeled for marine use that I use along with regularity Lucas Injector Cleaner, I use this stuff in motorcycle and small engines. Ethanol really gums up and swells the old rubber hoses when it sits inside the hoses, and be sure to use the proper ratio when mixing stabilizers.
Gasoline is said to begin to deteriorate after 6 months. A full tank is better than an empty tank when it comes to long term storage as it keeps moisture and rust from forming inside. Seasonal draining the gas if you want but the StaBil eliminates this, but if you want to drain 1/2 of old gas out, just dilute it with new gas and put it in another car engine is a way not to waste it.

Nothing wrong with winter driving, but don’t do short 15 minute driveway-warmup starts and then shut it down for another few weeks. So long as there’s no salt or water pools of salt water and spray, I go for a 30 min/ 30 mile highway drives in dead of winter.
