The message
from "Rod Craddock" contains these words:

30:1 'til you get manufacturer's info.
Most modern ones are 50:1 with *good quality* oil specified for use at
50:1.
Much cleaner and more environment friendly.

Pity it wasn't available in the '60s: the Ariel Arrow and Leader would
have been a lot more popular.
