Most of the supplied 200cc oil is already gone. Is it OK to use
vegetable / cooking oil as many websites suggest? It's hardly seems
worth investing in expensive Stihl / branded oil intended for more
powerful 2-stroke saws.

The organic bio-degradable oils are fine for forestry workers and such that use
the saws regularly. In occasional use, where the same oil may well remain in the
saw for a year, they can oxidise, become gummy, clog the oilways in the bar etc.
