when you say a "station" are you referring to a speed shop? I wish I could find 110 or even 104 at a station. In the south we don't even have Sunoco with 94.
Could it be E-85?-112 octane?
no, regular old boring gas station on the corner. Way off to the side by the diesel pumps is the 111 "Racking fuel" pump.
What is funny, in Ypsilanti there is a station with turbo blue 110 and he has it labeled as "Racing Fluid".
It's probably not e-85. In michigan you can still get good gas at the pump. If it's not leaded you can run it. Whether you need to or not depends on your tune.
You can run leaded if you don't care about your O2 sensor...
