Your leaf blower may not get used often enough to consume all of the fuel in the tank in a short period of time. This can be the reason a RedMax blower fails to run strong.
Old fuel, the wrong type of fuel, or an incorrect fuel mix will cause problems to develop in your RedMax leaf blower resulting in a loss of power, a failure to start, and potential engine damage.
Using the right kind of gas in your RedMax blower and properly storing the fuel will help keep it running at its best.
2-cycle RedMax leaf blowers use a gas and oil mixture at a ratio of 50:1. RedMax leaf blowers require unleaded gasoline with a minimum octane rating of 89 and a maximum ethanol content rating of 10%. This gas is mixed with a 2-cycle premium oil that is ISO-L-EGD and JASO M345 FD certified.
Mix gas and oil in a well-ventilated area. Wear safety glasses to protect your eyes.

Gas and Oil to Use in a 2-Cycle RedMax Leaf Blower
RedMax currently offers leaf blowers with 2-cycle engines. Know what type of engine is on your leaf blower. 4-cycle engines require straight fuel while 2-cycle engines require a gas and oil mixture.
Using the wrong type of gas in your RedMax can damage the engine. Never use straight gasoline in your 2-cycle engine. Straight gas runs very dry. Your internal engine parts won’t move freely when there isn’t sufficient lubrication.
Running a straight gas, without oil added in, will most likely result in you having to buy a new RedMax leaf blower.
RedMax Leaf Blowers Use a Gas to Oil Mix of 50:1
The 2-cycle engine on your RedMax blower has one fill port for a gas and oil mixture at a ratio of 50:1. This means it requires 50 parts gasoline to 1 part oil.
For example, one gallon of gas requires 2.6 ounces of oil. Refer to this chart for the right amount of oil to mix with unleaded gas.
| Gas to Oil Mix | 1 Gallon Gas | 2 Gallon Gas | 2.5 Gallon Gas |
|---|---|---|---|
| 50:1 | 2.6 oz Oil | 5.2 oz Oil | 6.4 oz Oil |
Type of Gas to Use in a RedMax Leaf Blower
When gas gets old, it begins to break down and become less effective. This can happen as soon as 30 days after purchase.
Always use fresh gas with a low ethanol content. Ethanol is a plant-based alternative fuel added to gas to make it more environmentally friendly.
Ethanol is not friendly to the small engine on your RedMax blower. It attracts moisture to the fuel system leaving behind varnish and gummy deposits along with causing corrosion.
The components on your blower may fail and fuel restrictions may form reducing the amount of fuel getting to the engine. This can result in your RedMax blower not starting or losing power.
RedMax leaf blowers require unleaded gasoline with a minimum 89-octane rating and a maximum 10% ethanol content. You can find this gas at your standard fuel station. Mix this gas with a 2-cycle premium oil.
Never use gasoline that has a greater ethanol content of 10% like those sold as E15, E30, and E85. These types of fuel contain up to 15%, 30%, and 85% of ethanol respectively. The best type of gas to use in a RedMax blower is an ethanol-free fuel.
Type of Oil to Use in a RedMax Leaf Blower
RedMax leaf blowers require a premium 2-cycle oil that is ISO-L-EGD and JASO M345 FD certified. RedMax offers its own branded 2-stroke engine oil. Do not put standard engine oil in your blower. This is not the same as 2-cycle oil.
Pre-Mixed RedMax 2-Cycle Fuel
For convenience, RedMax offers a pre-mixed fuel that contains an ethanol-free fuel and oil called MaxFuel. This is a convenient option to have sitting on the shelf. There is no need to deal with the mess of mixing oil and gas in a gas can.
| Manufacture | Gas to Oil Mix | 2-Cycle Oil | Pre-Mixed Fuel |
|---|---|---|---|
| RedMax | 50:1 | RedMax | RedMax MaxFuel TruFuel |
How to Mix Gas for a RedMax Leaf Blower
Determine how much fuel mix you want to prepare. Refer to the chart above for the amount of 2-cycle oil to add to the gas.
- Remove the cap from an approved gas can. Add unleaded fuel (minimum 89 octane rating & maximum 10% ethanol content) to a gas can.
- Add the appropriate amount of 2-cycle oil to the gas can.
- Replace the cap.
- Gently shake the fuel and oil until they are mixed.
- Add to the RedMax fuel tank.
Always mark your gas can with the type of gas and oil mix in the can. Mistakenly adding the wrong fuel to a piece of equipment can cause engine damage.
