AFAIK, fuel octane rating is not a power rating.

In any case, after thinking about my prior experiences I would say
Vanagons may well run ok on a small amount Coleman fuel. My vehicles
were carbed and had tanks that actually were empty when they ran out of
gas. I pulled 3 empty 2wd Vanagon tanks recently and they all still
contained a considerable amount of fuel. Adding Coleman fuel likely
results in a blend with a significant gasoline content. The
recirculating nature of the Vanagon fuel system would mix it up pretty
quickly.
