Experienced gardeners share their insights in answering this question :
Run 30:1 or 32:1. With modern synthetic oils, you could probably get along with 40:1 without trouble (and a lot less smoke). Good luck!

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.
1:25 = 1 part oil + 25 parts petrol, or 40 ml oil per litre of petrol when using other brands of oil. Any two-stroke engine oil you use in your petrol gardening tool must have the TC classification.
For a mixing ratio of 1 : 50 you need 5 litres of high-octane gas and 0.10 litres (100 ml) of STIHL two-stroke oil.
For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas. For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.
Air/Fuel Ratio (AFR)

AFR stands for air to fuel ratio. Fuel doesn`t burn on its own. It has to be mixed with air. AFR tells you how many parts of air are mixed with each part of fuel. For example, a 14.7:1 AFR (or just 14.7) means the mixture is 14.7 parts air to one part fuel.

The gas:oil ratio is the volume of gas produced at standard temperature and pressure, in relation to the volume of oil produced at standard temperature and pressure, used as a measurement for reservoir fluids.
You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you`re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. I would recommend using fresh gasoline that has an octane rating of 89.
Step 1: You`ll need STIHL 2-Stroke oil, an empty and clean fuel can and fresh unleaded fuel from a reputable petrol station. Step 2: Mix at 50:1 (20mls oil per 1L fuel) when you`re using STIHL 2-Stroke oil. If you`re mixing a larger quantity, check out our useful mixing chart.
100:1 – Mix 50ml of oil per 5ltrs of fuel.

Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.

If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
1 fuel oil is like a heavier version of kerosene. This means it has a higher boiling point, is more viscous and is less refined than kerosene. In comparison with No. 2 fuel oil, it is a bit lighter.
100:1 – Mix 50ml of oil per 5ltrs of fuel.

The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.

What is fuel mixture for solo motosage 60135
ANSWER : Some say 100:1 with synthetics. I use synthetics on 80cc and larger saws in the range of 40/50:1. I never go higher than that….saws are just too expensive to be stepping over dollars to pick up pennies. A lot of people are trying to make mixing ratios like some kind of mystery voodoo. You’ll always be fine in the 40/50:1 range with a good synthetic oil.
