40:1.
A 40:1 ratio is obtained by mixing 3. 2fluidounces (95ml) of oil with 1 gallon (4 liters) of unleaded gasoline. The owner's manual for your saw can be found at McCullochpower.com
40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/

Need to know the fuel oil mix for craftsman chainsaw Model #917.353736.
40:1
40to1
The fuel mix for the mculloch 60012312 is 40:1.
usually 32:1
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 checked a number of different sites and most recommend 40:1. One user recommended 50:1 and the Mac I had a few years ago, as I recall, recommended that mix. The slightly richer mixture of 40:1 is always safe but it will smoke a little more.
50 to 1 2.6 oz oil to 1 gal. gas
1/2 pint oil each gallon of gas.
use newer synthetic oil. it covers a broad range of fuel/oil ratios with one mix. it will allow you to use one fuel mix for all your 2cycle equipment. not marine though.
