I found something VERY interesting when I tried to read your plugs. Look down at the bottom...

Jon is right, for lots of reasons. First, reading plugs is tricky and not very accurate, especially these days with the myriad of different additives in today's fuel which pollutes the plug color.

Besides, your pictures are to unfocused to glean much from, even if we could read plugs accurately.

Best to use an O2 sensor, or at least an exhaust gas analyzer.
