Wessa all this oil ratio stuff is easy if you know why
The rule is if your engine has allready been run in and it runs needle bearings at the big end then 50:1 is the go. If your engine is low hp enough or old enough to run the white metal shell type bearings then 25 to 1 is the ratio, no other reason comes into it.

Going leaner than 50:1 (50:1 = needle bearings) on oil is reserved for the higher quality oils, like synthetic and a few outboard branded oils. Going richer is reserved for those that want to run the risk of jamming rings etc. nq

ALL Mercs are 50:1... except oil injected which obviously are mixed by the Autoblender and brand new motors which have a Break in period where higher ratio 25: 1 is advised. Racing Mercs are also higher (25:1)
The little 1. denotes oil injection and suggests that the first tank should be pre-mix and in conjunction with the autoblend would make it 25:1
The little 2 refers to the first tank (new motor) to be 25:1 which is double the oil. If your motor is not oil injected, it's 50:1

Thanks,
I will keep it at 50:1
