I see from Ed's last E mail that he mixes 6 oz. of 2 stroke oil
to 18 gal. US. I mix 4 oz. to every 5 US gal. or 19 litres, I
got this from Tracey's book, did I miss something ?

You may be able to get away with less oil when using synthetic 2 stroke oil.
I have stayed with mineral based oil and now use 1 oz per gallon of fuel to
be on the safe side...  Racing Beat was the source of the original figure of
4 oz per 5 gal.
