Before I start up my ancient Pope 320 rotary valve engine, I just wanted to double check the correct fuel mix.
In my Victa Mayfair I use about 120ml semi-synthetic to 5 litres. The manual says 200 ml to 5 litres, but I'm guessing that would be the old mineral oil not modern semi-synthetic?
But the manual for the Pope 320 engine says 1/2 pint to 1 gallon, which translates as 284.131ml to 4.54 Litres. That is nearly twice as much as what I've been using in the Victa!
I am sure they were talking about mineral oil in those days, so maybe with semi-synthetic you would not need that amount?
Can anyone please clarify the correct mixture for both Victa Mayfair and Pope 320. I'll be using the ByNorm 2 stroke oil, which I gather is semi-synthetic?
