There is no correct answer. 50:1 is only a general guide, a
rule-of-thumb.

Indeed, actual mixtures vary a lot between different engines but it was the
point about whether 50:1 = 1 part oil added to 50 parts petrol or whether
50:1 = 1 part oil added to 49 parts petrol making a 1 *in* 50 mixture.

Thats already been answered (and its the former).

"with petrol/gasoline at a volumetric fuel-to-oil ratio ranging from
16:1 to as low as 100:1."

Old Seagull outboards used to run on 10:1.
