fuel stabilizer

(1/1)

Courtesan:
Good Afternoon ..

Last  year, with some assistance we removed my atomic 4 and had it rebuilt; runs like new again ! 
I also drained the fuel tank while the A4 was out and replaced with 15 gallons of hi octane fuel. The engine was winterized after haul out but I forgot to add fuel stabilizer as I've done in the past.

My question .. am I safe starting the engine with this "unprotected" fuel or should I drain the tank again.
I just don't want to take any chances


thanks,

Bacteria won't grow in gas, so the only concern is water intrusion.

Using a hose, siphon a sample from the very bottom of the tank and examine it in a glass container.  Any water or phase separation should be obvious.

If your tank fittings and fill cap seals are all good, you are likely alright.   I regularly leave a full tank of gas (to minimize air exchange) over the winter with no stabilizer and have had no problems in 8 seasons.  YMMV  :)
