McCulloch recommended 40:1 using their oil, 20:1 all other oils. I use 32:1 with good quality 2-stroke oil, has worked fine for years.
If using an oil other than McCulloch, the ratio is 40:1. Brand Specific McCulloch two cycle oil is 20:1.
16:1
The full ratio according to the embossed diagram on my Mac Cat 435 fuel cap is 40:1. Hope this helps.
If using an oil other than McCulloch, the ratio is 40:1. Brand Specific McCulloch two cycle oil is 20:1.
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.
40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
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.
The fuel mixture for the McCulloch Power Mac 320 chainsaw is typically a 40:1 ratio of gasoline to 2-stroke oil. This means for every 40 parts of gasoline, you should mix in 1 part of 2-stroke oil. It's important to use high-quality oil specifically designed for 2-stroke engines to ensure optimal performance and longevity. Always refer to the owner's manual for specific recommendations and guidelines.
The McCulloch Pro Mac 510, like many two-stroke engines, requires a fuel mixture of gasoline and oil. Typically, a 50:1 ratio is recommended, which means mixing 2.6 ounces of two-stroke oil with one gallon of unleaded gasoline. Always ensure to use quality two-stroke oil designed for air-cooled engines. Check the user manual for any specific recommendations or adjustments based on your local conditions.
Mac 310 fuel/oil ratio is 40:1
When came out it called for 16:1, but with todays fuels 32:1 mix of a good quality oil will suffice. Most 50:1 oils should work but get a name brand
I have model number 60003816 and I run 3oz of oil to 1 galion of gas. Works good but I'm not positive that's what is recommended. The manual for that chainsaw requires a 20:1 mixture of non-McCulloch two-cycle oil. That is 6.4 oz. per gallon of unleaded gasoline regardless of what it says on the oil container.
