Do Leaf Blowers Take Mixed Fuel?

Have you ever wondered if leaf blowers can take mixed fuel? For many homeowners and gardeners, using a leaf blower is key to keeping their outdoor space looking neat and tidy. And when it comes to powering these devices, you may be wondering what type of fuel your model takes.

We’ll discuss whether or not a leaf blower should take mixed fuel for efficient operation on various terrains. With this information in hand, you can make the best decision for how to care for your device so that it serves its purpose more efficiently.

Do Leaf Blowers Take Mixed Fuel?

Yes, leaf blowers take mixed fuel. There are two main types of leaf blowers available on the market today: gas-powered blowers and electric-powered blowers. Both types can be effective, but they require different kinds of fuel. Gas-powered leaf blowers use gasoline while electric-powered models use electricity.

Mixed Fuel In Gas-Powered Leaf Blowers:

Most gas-powered leaf blowers require regular unleaded gasoline as the fuel source, though some can also use ethanol blends such as E10 or E15. However, it’s important to note that not all gas-powered leaf blowers can use mixed fuel, some have carburetors that are specifically designed for either regular unleaded gasoline or E10/E15 blends only.

It’s important to check the manufacturer’s instructions before adding any kind of mixed fuel to your leaf blower to ensure compatibility with your particular model.

Mixing Up Your Own Fuel For Your Gas-Powered Leaf Blower:

If your gas-powered leaf blower does allow for mixed fuels, you can mix up your own fuel blend at home using a combination of regular unleaded gasoline and ethanol. When mixing up your own blended fuel, keep in mind that most manufacturers recommend using no more than 10 percent ethanol (E10) in order to maintain optimal performance and prevent damage to the engine over time.

Any higher percentage could result in decreased power and performance as well as increased emissions levels from the engine.

How To Mix Oil And Gas For A 2-Cycle Leaf Blower?

Maintaining your 2-cycle leaf blower is essential in order to keep it running properly and efficiently. To successfully mix the oil and gas, you must use a two-stroke engine oil formulated specifically for air-cooled engines, as this will ensure optimal lubrication. Additionally, the oil should be mixed with gasoline at a ratio of one part oil to fifty parts gasoline.

It’s important to ensure the mixture is not too lean; otherwise, your engine could suffer damage. Once you have measured out your desired ratios of gas and oil, shake the container well to thoroughly incorporate them before adding them to your fuel tank.

With some basic knowledge and with the appropriate tools on hand, you can easily mix up a batch of fuel for your 2-cycle leaf blower yourself.

Do All Leaf Blowers Take Mixed Gas?

The answer is no, not every leaf blower needs the gas to be mixed before use. For Leaf blowers that come with four-stroke engines, you don’t need to mix the gas with oil before use. This is because this model has a separate gas and oil chamber and mixes them automatically for you.  

However, if you’re using the two-stroke model, then using regular unmixed gas is not recommended because this can damage your equipment.

How To Mix Gas for A Leaf Blower? – Exact To Gas Ratio For Leaf Blower

To ensure your leaf blower operates optimally, it’s important to get the gas and oil balance just right. Having too little gasoline can stop the engine from starting or cause excessive wear on its moving parts.

Too much oil not only causes smoke production but also leads to fouled-up spark plugs and other components like reed valves and fuel lines prematurely wearing out. Get that perfect mix – for a perfectly performing machine.

When refueling your gas leaf blower, make sure to use the gasoline blend recommended by the manufacturer. Standard unleaded fuel with a 10% ethanol content (E10) and an octane rating of 87 or above should do the trick, this ensures engine performance is not affected negatively. Going beyond E15 could cause damage to your machine’s motor, so it’s best avoided.

Keeping your leaf blower in optimum condition requires paying special attention to its fuel. Stale gas is created when water mixes with ethanol-enhanced gasoline, and it can cause significant starting difficulties for the engine if used.

When mixing fuels, the ratio of oil must be taken into account – contemporary machines are often best served by a 50/1 mix while an older version may require 40/1 instead.

Get ready to enjoy a clean performance from your leaf blower by getting just the right blend. The different Gas-Oil ratios are:

For Ounces:

  • To create a 20-to-1 blend, you’ll need 6.4 ounces of oil based on a one US gallon bottle of gas (equal to 128 US fluid ounces). 
  • For the same container, a 30-to-1 ratio will take 4.3 ounces of oil. 
  • A 32-to-1 mix needs 4 ounces of oil per gallon.
  • One of the most frequent ratios for two-cycle engines today is 40 to 1. You’ll need 3.2 ounces of oil to get that from one gallon of petrol. 
  • In contrast, a 45 to 1 ratio requires 2.8 ounces of oil.
  • Another frequent guideline for newer leaf blower types is a 50-to-1 ratio. Add 2.6 ounces of oil to a gallon of gas to produce the proper 50:1 ratio.
  • A 60-to-1 mix requires 2.1 ounces of oil
  • An 80-to-1 blend requires only 1.6 ounces.

For Liters:

  • For a 20 to 1 ratio; For a 5-liter gas container, you’ll need 250 mL (or 1/4 liter) of oil to cover the whole container. 
  • Add 167 ml of oil to the gas at a 30-to-1 ratio. 
  • If you’re using a 32 to 1 ratio, you’ll need 156 mL of oil.
  • A 40 to 1 ratio is simple to calculate. For every 5 liters of gas, you’ll need 1/8 of a liter (125 ml) of oil. 
  • 111 ml of oil is required at a 45 to 1-ratio.
  • Measure out 100 mL (1/10 liter) of oil for every 5 liters of gas in a 50-to-1 ratio. 
  • A 60-to-1 ratio requires 83 ml of oil
  • But an 80 to 1 mix requires just 63 ml.

Do Stihl Blowers Use Mixed Gas?

Yes, they do. The 50/1 ratio is also used by STIHL on their gas-powered leaf blowers. This brand, on the other hand, suggests that you use STIHL MotoMix.

The preset mixture eliminates any guessing from the process because it clearly states the right ratio for mixing. You’re also less likely to violate a new machine’s warranty if you use the proper gas.


We can say for sure that a leaf blow lives up to its purpose because it saves us a lot of time and effort, and it is less taxing on your back than laborious raking. However, you must provide your leaf blower with the proper gasoline.

It will lock up and stop operating if you do not do so, and the cost of repairing it may be expensive.

Always make sure you use the proper fuel in your machine, mixed or regular, whether you make your own or buy a ready-made mixture.
