7423 I have been wanting to try the C10 unleaded have been running the C12 in my 5.0 liter stocker. Have you run both these fuels was there any performance differance? I want to run unleaded for O2 sensors and my wide band sensor to keep from killing them. The C10 has a lower octane and was thinking with the lower compression engine should be a performance advantage. PM me if you want.
