From 1975 when I owned a mac 3 it was fine at 25 to 1 regards
the mix for a mac 3 a is 25/1 rotio.
Mac 310 fuel/oil ratio is 40:1
The Fuel mix for the MAC 3 outboard motor typically requires a ratio of 50:1, which means mixing 50 parts gasoline with 1 part two-stroke oil. It's essential to use high-quality, unleaded gasoline and a good two-stroke oil designed for marine engines to ensure optimal performance and longevity. Always consult the owner's manual for specific recommendations, as variations may exist depending on the model or year.
16:1
The full ratio according to the embossed diagram on my Mac Cat 435 fuel cap is 40:1. Hope this helps.
40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
A "Big Mac", one company's trademarked name for a certain kind of hamburger, is a mixture, because it contains many different compounds.
50:1 is incorrect. That mixture will not allow enough compression and the unit will be very hard to start, if at all. That mixture works well for Sthil products. If using an oil other than McCulloch, the ratio is 40:1. Brand specific McCulloch two cycle oil is 20:1.
If using an oil other than McCulloch, the ratio is 40:1. Brand Specific McCulloch two cycle oil is 20:1.

The fuel mixture for a McCulloch Mac Cat 35cc super 16 is typically a 40:1 ratio of unleaded gasoline to 2-cycle engine oil. This means you would mix 3.2 ounces of oil with 1 gallon of gasoline. Be sure to use a high-quality oil specifically designed for 2-cycle engines.
