I think much has to do with how the motor is used. Racing at wide open I would use more oil. For fishing I would mix at 40/1 just because the motors are older & the metals used to build has improved too. Then comes the politics of the EPA & even at one time going to 100/1, We know how that worked. I also pay the price of manufacturers premix oil too except ScottAtawater. I use Mercury brand oil in the Scotts. Sad to say the price of premix will not enter into the equation because I don’t get out that often. 😥
