Great stuff Fred. I love that smell. Unfortunately using Castrol racing oil
means more frequent engine rebuilds as it gums up the works. Maybe a bit of
castor oil in the fuel is the way to go. Presumably though this will lower
the overall octane level. Or would the effect be insignificant.
Is it 100% castor oil that you buy?
