Elson,,, thanks for you test and reports, I know how this can bring on flak to ones self,,,
as for H1R vs MC-1, when I called BellRay last spring, BellRay told me that H1R will burn cleanest of the 2,,,
again thank you for your time !!

They also told you that H1R contained octane booster when it didn't.
I have used both H1R and MC1. Although it wasn't a controlled "test" in my experience the MC1 is cleaner and runs cooler. I am going to do a short "controlled" test of MC1 here before very long using a MVVS 1.6 gasser.
