I ran my Honda pressure washer today till it ran out of gas to store it for winter. There is still a tiny bit in the bottom of the gas tank but if I turn it upside down pump oil start leaking all over the place and it in new oil. WIll it be safe to just leave it in there till spring? This gas was treated with Sta-Bil this past spring in my 5 gallon gas can I use for all my OPE. Thanks! P.S. I pulled the start cord a few times to get the excess water out of the pump. I think I got most of it. Do I still need antifreeze? Last winter this was all I did and all still works...just don't want "luck" to run out if you know what I mean...lol Thanks!
