Do you live in a heavily regulated state like California with tough laws on emissions? Then you might want to use a 50:1 fuel mix since it will lead to lower emissions.
But if the manufacturer recommends a different oil mix, it can lead to confusion. So, wondering if you can use 50 to 1 in 40 to 1 engine saw?
Yes, you can use a 50:1 ratio oil mix in 40:1. A 50:1 ratio oil mix with full synthetic 2-stroke oil will grease any saw.
We’ve only provided you with an excerpt. If you want to learn more, we advise you to read on.

Is it Possible to Use 50 to 1 in 40 to 1?
50:1 and 40:1 denote the ratio of oil to gas mixture in the fuel mix. Manufacturers tend to advise particular fuel mixes for their saws.
For a long time, it’s been recommended to follow their instructions. But thanks to innovation in oil you can use either 50:1 or 40:1 oil mix.
Many 2-cycle synthetic oils available today can be used in any machine. This is regardless of the OEM specification ratio.
Improvement of synthetic oil is why you can use a 50:1 oil mixture in any engine. This allows you to use a 50:1 oil mixture in a four-stroke or older two-stroke engine.
Furthermore, the difference between the two oil combinations is less than most people believe. This is especially true if the saw has been calibrated appropriately.
When changing the oil mix, it is critical to ensure that the engine is tuned. If you go to a 40:1 mix, you should calibrate your saw. You must also do it if you switch to a 50:1 mix.
If you don’t follow our above advice when using the two oil mixes then your saw may idle.
After reading all the above, do you think it would be better to buy a whole new saw? If so, then we propose you take a look at these.
How to Make 40 to 1 and 50 to 1 Oil Mixture?
Small engines frequently have two cycles and are even referred to as a two-stroke engine. If the motor only has one fill valve for engine oil and gas.
Then it’s a two-cycle engine. To work correctly, it necessitates a precise blend of oil and gas. In such engines, most people utilize a 50:1 oil mix.

50:1 Oil Mix
For the 50:1 gas and oil mixture use 2.6 ounces of oil for 1 gallon of gas. You can also follow the chart we’ve created below:

We hope that the two tables we’ve provided above are of help. Now that we’ve dealt with the portion of gas and oil to be used. We’ll be covering how to make the oil mix.
- Synthetic Oil
- 5 Gallon Gas Can
- Ethanol-free Gas
- Measuring Cup
You can easily find the above-mentioned components at your nearest hardware store.
However, if you have never bought ethanol-free gas before, I recommend you take a look at some of these:
No products found.
- First, ensure that the gas can you’re using is completely empty. You’ll need to do so to ensure that you don’t ruin the oil mix.
- Properly measure and pour the oil into the can. Then add the proper ratio of gas into the can.
- Now, shake the newly mixed oil and gas with all your strength. You want to do so to ensure proper mixing of the oil with the fuel.
We hope that the tables we’ve provided and the steps we’ve outlined come in handy. However, if you think it’s too much then you can also use pre-mixed fuel. This is our list of preferred commercially available premixed fuels.
Frequently Asked Questions
Is there more oil in 40 to 1 than in 50 to 1?
A 40:1 oil mix ratio represents that 40 units of gas are used for every unit of oil drop. Consequently, there are 50 units of gas in a 50:1 fuel. As a result, a 40:1 oil blend is thicker and lubricates faster than a 50:1 oil mix.
What occurs if you operate a saw on straight gas?
If straight gas is applied, this could damage and destroy the piston and crankcase in minutes since the gas burns out these sensitive parts rapidly. Instantly dump the tank into a different fuel container.
For which length of time can 2-stroke gas sit?
No fuel, mixed or unmixed, should be stored for more than 30 days. The use of outdated fuel can reduce a motor’s power output, create buildup and obstruction in engine components, and render starting more difficult. Storing fuel with a fuel additive can help extend its life.
Is bar oil required for electric chainsaws?
With proper lubrication, all chainsaws, either gasoline or electric, require chain and bar oil. The chainsaw bar is lubricated by an automated oiler. Chain and bar oil lowers resistance and heat while also reducing engine wear and extending the life of your chainsaw.
The article and all it contains should have answered your question can use 50 to 1 in 40 to 1.
Despite the warnings that saws tend to come with, you can use a 50:1 oil mix in a 40:1 engine without any repercussions. So, use the 50:1 oil mix without any worries.
