Gas and Oil Mixture Yard Machines Leaf Blowers Use

Purchasing and mixing the right fuel for your Yard Machines leaf blower is essential to minimize the damaging effects of fuel. Taking time to learn how to choose and care for your leaf blower’s fuel can save you time and money in repairing any fuel damage.

Yard Machines handheld leaf blowers require a gas and oil fuel mixture at a ratio of 50:1.

  • 50 parts gasoline with a minimum 89-octane rating and maximum 10% ethanol content.
  • 1 part 2-cycle engine oil that is ISO-L-EGD and JASO M345 FD certified and made for air-cooled engines.

Old Gas

It’s not good to allow fuel to sit in your Yard Machines leaf blower for extended periods. This is because gas can begin to break down as soon as 30 days after purchase.

Ethanol, the alternative fuel added to most gasoline, naturally attracts moisture from the air to the fuel system. The water and ethanol mixture separates from gas over time leaving behind varnish and gummy deposits.

Not only is this mixture highly corrosive to the fuel system and engine, but it also causes fuel restrictions and component failures.

Ethanol is not good for small engines. You need to avoid gas that includes ethanol at contents greater than 10%.

You should only purchase fresh fuel and consume it within 30 days. I understand it can be difficult to know exactly how much gas you’re going to go through in this time frame.

Because of this, add a fuel additive to stabilize the gas to make it last a little longer.

Some 2-cycle oils include a fuel stabilizer. Don’t assume the stabilizer will last longer than 30 days unless that information is provided by the manufacturer. Some stabilizers will last up to 30 days while others can last up to two years.

You can also add a fuel stabilizer like Sea Foam Motor Treatment or STA-BIL.

Gas and Oil Mix to Use

Don’t make the mistake of adding straight gas in a 2-cycle Yard Machines leaf blower or you may end up having to buy a new leaf blower.

Straight gas runs very dry and will cause the engine to seize and quit. Without oil added to the gas, the engine doesn’t get the lubrication it requires for internal parts to move freely.

A Yard Machines leaf blower engine will have one fill port for an oil and gas fuel mixture.

Yard Machines 2-cycle equipment requires a fuel consisting of a gas-to-oil mixture at a rate of 50:1: This means 50 parts gas is mixed with 1 part oil.

When creating this mix, use unleaded gasoline with a minimum octane rating of 89 (mid-grade) and maximum ethanol content of 10%. Add a 2-cycle premium oil that is ISO-L-EGD and JASO M345 FD certified.

How to Mix Gas and Oil

  • Use the chart below to determine how much fuel mix to prepare.
  • Remove the cap from an approved gas can. Add unleaded fuel (minimum 89 octane rating & maximum 10% ethanol content) to a gas can.
  • Using the chart for ounces of oil required, add the 2-cycle oil to the gas can.
  • Replace the cap.
  • Gently shake the fuel and oil until they are mixed.
  • Add to your Yard Machines leaf blower fuel tank.

You can use this 2-cycle engine oil by MTD. Another alternative is this 2-cycle mix by Kawasaki. It comes in 5.2 oz. and 6.4 oz. bottles that can be mixed with 2 gal. or 2.5 gal. of gas respectively for a 50:1 mix.

Using Ethanol-Free Fuel is Best

To avoid the negative effects caused by using an ethanol-based fuel, it’s best to use an ethanol-free fuel in a Yard Machines blower. This is the more costly option for fueling your blower.

An ethanol-free 50:1 fuel mix is ready to pour into the fuel tank. This is not only a great option for the blower, but it’s also a very convenient option for the user.

I love having fuel on hand to use whenever I need it. There’s no more running to the fuel station to fill up on gas or the mess involved. I use an OEM pre-mixed fuel like those sold by STIHL or ECHO. Some aftermarket cans of pre-mixed fuels have been known to cause running issues.
