I ran automotive coolant in my old Honda V65 for 15 years. The rear two cylinders tended to run hot anyway, so I flushed the system every year and tried to keep the mixture at 50/50. I used a motorcycle coolant called "Engine Ice" (available at a lot of places) for a while. It didn't make a noticeable difference, so I switched back to whatever I could get on sale at the neighborhood AutoZone.
