Newbie/ part timer doing a few accounts next year. Bought my Q36 this fall to save money. Only got just over 3 hours on it this Nov/Dec before I had to store it away for winter. My questions 1. In the manual it says for long term storage add a fuel stabilizer. What is this? Is this the same as the STP gas treatment I sometimes use in my car or something else? If its something else, give me a brand name and where to get it. 2. If adding the fuel stabilizer, should my tank have close to a full tank of gas? Thanks for your help.
