I have too many small 2-cycle engines and keeping track of the oil/fuel

now have ratios of 25:1, 32:1, 40:1 and 50:1, with factory recommendation of
regular gas for one engine and premium gas for another, *so putting the
wrong fuel into the wrong engine is very likely giving enough time. Someone
posted sometime ago that he only use one ratio with one particular type of
oil and never had problems over a long period of time with various 2-cycle
engine. Anyone know what this ratio and type of oil are or would like to
comment? Thanks for reading.

Using premium gas in all your tools won't hurt anything, and there is
no such thing as too much oil. One mix, 25:1, 93 octane. Done.
