Hi Auto Doc!
Thanks for caring enouph to seek clarification. I just adjusted header to include "Lawn Boy".
What I posted was my own measurement of how much my 6.5 Dura Force fuel tank holds, (60oz.).
Then I posted the ratio of my fuel,(60 oz), to achieve a 50:1 gas/oil mix.
That came out to be...
I measured how much my tank holds: 60 oz., (rounded up), fuel.
Means given 50:1 ratio, 36cc or 1.22 oz. 2 stroke oil per 60 oz. or 1.75 liters gasoline.
How's that for simple conversions?
