414TATA Posted July 21, 2016 Share Posted July 21, 2016 I will be garaging my Buick for approx. 3 months of winter. Winters here are mild with a low outside of not lower than 27F (unusual) garage temp probably no lower than 50 degrees. My question is: Is it okay to leave some fuel (less than 4 gallons) treated with an additive in the tank? i really don't want to drain the tank or leave it full. your opinions please. Thanks Wayne 1941 Buick Link to comment Share on other sites More sharing options...
39BuickEight Posted July 21, 2016 Share Posted July 21, 2016 (edited) Yes that is fine. We do that in ours cars, boats, and power yard equipment every winter. I think it's often recommended to fill the tank, but I don't have any problems whether they are full or not.

Larry Schramm Posted July 22, 2016 Share Posted July 22, 2016 (edited) My normal storage for the cars for the Michigan winters is to change the oil & filter, fill it up with gas, and then park it for the winter with minimal driving after the oil change. Oil change, gas station, storage. On the newer cars I usually disconnect the batter or put a battery tender on the car. I do not start it until spring.

Joseph P. Indusi Posted July 22, 2016 Share Posted July 22, 2016 Your winter temperatures are similar to mine. I use fuel stabilizer but I found that I can drive the car year round , at least once a month through winter by just picking a clear dry day. I don't just start it up, I take it for a 20-30 minute drive and exercise all of the systems. Works for me. Joe, BCA 33493 Link to comment Share on other sites More sharing options...
414TATA Posted July 22, 2016 Author Share Posted July 22, 2016 Thanks for the advice gentlemen I will not be in the area so the car will not be driven during those 3 months. I will disconnect batt and leave treated fuel in tank as advised above. Wayne Link to comment Share on other sites More sharing options...
