Winter gas started pumping September 15th and, like clockwork, the Squire started running poorly. Just down on mpg at first, then a few misses under acceleration, then a lot of misses. So, I pulled the plugs, just like last winter around this time, and the year before.
Yup, scavenger deposits. Some of the worst yet, too. I remembered to take pictures this time.
The plugs are in order 1-6. You can see the leaner/hotter cylinders don't crud up as much as the perfect mixture 2, 5, cylinders. The 3, 4 cylinders showed evidence of gobs that had been knocked loose and then reformed, maybe a few times. They are as bad (or worse) around the center electrode and insulator as the 2/5 plugs. I pulled the plugs last July after some minor mixture adjustments and they were clean, a nice light tan. No globs. So I'm convinced it's winter gas additives.
I don't know what kind of toxic waste the oil companies are disposing of in winter gas, but it needs a -hot- combustion chamber to keep deposits from forming.
