What is the oil-gas ratio for a Husqvarna chainsaw? The oil-gas ratio for the Husqvarna chainsaw is 50:1. But why is this Husqvarna chainsaw fuel mix ratio so important, and what happens if you do not maintain this ratio?
In this article, we will elaborate on all the details about the gas or fuel mix ratio of the Husqvarna chainsaw. You will also get to know which Husqvarna chainsaw model requires what type of fuel fix for different purposes.
A Husqvarna chainsaw is lawn maintenance equipment that uses a two-cycle engine. This engine doesn’t have an oil reservoir that can contain engine oil and lubricate the piston.
Thus you need to mix the oil with the gasoline to run this two-stroke engine. Here, the gasoline and the oil need to be mixed with a certain amount at a specific ratio.
So without any further ado, let’s see what you need to know about the Husqvarna’s recommended fuel mix ratio!
Husqvarna Chainsaw Fuel Mix Ratio
So as you know, the Husqvarnachainsaw fuel to oil ratio is 50:1 (2%). And it is applied to all the two-stroke engines up to 75cc. This includes the Husqvarna 450, 455, 460,439, 545, 555, 365 models.
On the other hand, the Husqvarna chainsaw with an air-cooled two-stroke engine over 75cc is recommended to use a 33:1 fuel to the oil mixing ratio.
Here’s a simple table chart of how much engine oil and fuel you have to mix according to the recommended ratio of 50:1 or 2%.
| Petrol Per Liter | Oil Per Liter 2% |
| 5 | 0, 10 |
| 10 | 0, 20 |
| 15 | 0, 30 |
| 20 | 0, 40 |
Here’s a simple table chart of how much engine oil and fuel you have to mix according to the recommended ratio of 33:1 or 3%.
| Petrol Per Liter | Oil Per Liter (3%) |
| 5 | 0, 15 |
| 10 | 0, 30 |
| 15 | 0, 45 |
| 20 | 0, 60 |
Husqvarna Concrete Saw Fuel Mix Ratio
The mixture of fuel and oil ratio for the Husqvarna chainsaw is the same for the Husqvarna concrete saw (Consaw). The concrete cut-off saw needs proper maintenance, including the right fuel-oil mixing.
Here the ratio of 50:1 denotes that you should mix 1 part of two-stroke oil for every 50 parts of gasoline. Using the Husqvarna two-stroke engine oil is recommended for the oil-gas mixture.
How to Mix Fuel for Husqvarna Chainsaw
Now that you know what is the mix ratio for a Husqvarna chainsaw, you should also pay attention to how to mix it. Here are some simple steps you can follow to create the perfect mixture of oil-fuel.
Step 1: Use a high-quality clean gasoline can. A suitable container will prevent the fuel from evaporating and extend the shelf life of gasoline for chainsaws.
Step 2: Now take half amount of fuel in the can with a certain amount of two-stroke oil and add the remaining half fuel to the gas can.
Step 3: Then tight the gas can cap securely and shake the can gently to create a perfect mixture.
Step 4: After mixing the gas and oil gently, fill the chainsaw fuel tank carefully and make sure to clean the fuel cap.
What Happens If You Don’t Maintain The Ratio?
Mixing the right amount of fuel oil is a must for your Husqvarna chainsaw engine. Now, what if you don’t maintain the recommended Husqvarna 435 chainsaw gas to oil ratio in your Husqvarna 435 ranchers?
Well, if you use too much two-stroke oil with fuel, your Husqvarna chainsaw engine will give poor performance. Besides, the engine might face trouble running or even starting. Too much two-stroke oil generates carbon buildup, which results in exhausting smoke clouds.
On the other hand, if you mix less two-stroke oil with fuel than the Husqvarna 55 chainsaw fuel mix ratio. The Husqvarna engine will get overheated as it can’t lubricate enough oil to the piston. As a result, it might lead to internal damage to the machine.
Some of the two-stroke oil may require a fuel stabilizer. So check the bottle labeling before mixing the oil to fuel.

Frequently Asked Questions (FAQs)
Are all Husqvarna chainsaws 50 to 1 mix?
Technically no, all Husqvarna chainsaws are not 50 to 1 mix. The 50:1 ratio would work for the Husqvarna chainsaw engines up to 75cc. But engines over 75cc require a fuel-oil mix ratio of 33:1
What happens if I use too much 2-stroke oil?
If you use too much 2-stroke oil with fuel, your Husqvarna chainsaw engine will give poor performance. Besides, the engine might face trouble running or even starting. Too much two-stroke oil generates carbon buildup, which results in exhausting smoke clouds. And this will create blockage in several parts of the engine.
What is the mixture for 50 to 1?
The mixture for 50 to 1 denotes mixing 1 part of two-stroke oil for every 50 parts of gasoline. If you calculate in a liter, it will be 20-milliliter 2-stroke oil per 1-liter fuel or gasoline.
How much 2-cycle oil do you put in a gallon of gas?
2.6 fluid ounces of 2-cycle oil should be put in a gallon of gas for a 50:1 Husqvarna 236 chainsaw fuel mix ratio.
Conclusion
Hope you have got everything you wanted to know about the Husqvarna chainsaw fuel mix ratio. It is very important to use the proper fuel-oil ratio. The two-stroke helps in lubrication and potentially saves the engine from destruction.
Also, keep in mind that you shouldn’t store the mixture longer than one month, even if it’s only fuel. Old fuel or gasoline damages engine power output and builds blockage in several parts.
