      Ok, this is probably a stupid question, but on the underside of my fuel filler cap (1978 TS250/1), there is a measure for presumably adding two stroke oil to the fuel in the tank.
      My question is, how much fuel does one cap of oil equate to?
      Thanks for any help

      Ah I asked that a year ago it is one cap = 1 gallon of petrol ratio is 50/1

      Hope this helps Stuart

      On my 1978 TS250/1 it is written on the cup – 1 gal – 50-1.
      Admittedly I had to clean the cap with a wire brush and bingo it emerged!

      I run my mz’s at 33 to 1 that means 1 cap per 3 litres of fuel. 6 litres =2caps . 9 litres = 3 caps works well for me

      Also I use cheap carplan 2 stroke oil (three litres for a tenna from gsf)

      Hope that helps someone
