My method, which may or may not be 'the best', is to toddle down to the close gas station, for its last ride, pour/squeeze in enough to 'treat' the 22+ gallons, fill to the brim, drive home and squirt in a few more ounces. My method may be overkill...one may be able to just pour in enough to cover the tank volume, fill tank, drive home, park it. ;>)

Buy the bigger bottles that cover 20+ gallons, and be careful with the squeeze/pour as its an odd bottle shape and process. The X's filler opening is slightly problematic in allowing for a clean pour of Stabil.

No battery tender type charger, Naz?
