Wildcat ratio
Hi Danimoor. McCulloch recomends 40:1 if you are using their genuine oil or if not, use a good SAE 40 two stroke oil at 20:1. I use 25:1. Your profile just said that you lived somewhere on earth so I don't know whether to put this ratio in imperial or metric so I'll try both. 20:1 ratio is 50mls of oil per litre of petrol or 1&1/2 oz oil per U.S. quart or 3/4 oil per U.S. pint. I hope that helps.
