The car in question is a GT500, not that it matters. Due to various factors, one being I have an "outlaw" car, meaning it doesn't pass State emissions, so I only drive it on a very limited, but extremely fun manner. It is still registered and insured, as your emissions test is not tied to your registration. I typically take it out on a 10 mile loop in the country, at least once a month, during driving season. Fully enjoy every mile I put on the car, but want to keep the miles low at the same time. I filled up the first week of December, 2017. I am down to about a quarter of a tank, having put about 80 miles on it this year. I filled up with 93 Shell V Power, and the recommended amount of Sta-Bil. I don't drive the car hard, just normal driving, because I know gasoline degrades over time. I've always been told, to fill the tank up prior to winter, because winter here lasts about 6 months (November through late April), to help keep moisture out. The problem is, I don't drive the car enough to really burn through the gas, in a timely manner. Would I better off, during driving season, to only put 5 gallons in at a time, versus filling it up, so I always have fresh gas? I really see filling up now, lasting me until December, but I'm sure the gas would get stale between now and December. Over winter, I'm assuming it's better to have the tank full, but it limits how hard I can drive the car, the following spring/early summer. Any thoughts? Thanks!
