How much oil do you mix in to every litre of fuel on a model c and is it OK to use unleaded or do I need to add lead adative

No need for a lead additive. Use ethanol-free fuel if you can. The C & D engines have a bushing rod small end bearing so use a very good quality 2T oil at 4%.

1 litre = 1000cc

4% 0f 1000cc = 40 cc (or 40ml if you prefer!) :)
