I would say Mobil made the can Jack.
Seeing what mowers went with what brands is interesting.
Most brands recommend Wakefield Castrol (or castrol) at the beginning, off the top of my head the only brands I can remember not recommending Castrol was Rover, Sunbeam (Ampol), Southern Cross (Shell) and Turner (Mobil).
At the beginning of the 60s most brands that still survived turned from Castrol to BP. Pace was strange during this time, it was in a transitional period which saw it go from Castrol (also formerly Wakefield Castrol, which is a very hard can to get), to Ampol and then finally to BP within a very short time.
Pope would be a strange one too, it started making its first cans in the mid 1950s, but it wouldn't recommend a fuel brand until it joined Simpson in the early 70s, it would then team up with Mobil.
Its pretty much another huge part of the mower world. I would say most cans would have been made by a petroleum company.
