Old fuel in your Poulan Pro chainsaw is often the primary reason you begin to experience starting or running problems.
To minimize the negative effects of fuel, it’s important to choose the right type of gas and oil. You must understand how to prepare the fuel mix and how to properly store it.
Poulan Pro chainsaws with 2-cycle engines use a gas and oil mix at a ratio of 40:1 or 50:1 depending on the model.
- Unleaded gasoline with a minimum 89 octane rating and a maximum ethanol content of 10%.
- 2-cycle premium oil that is ISO-L-EGD and JASO M345 FD certified.
Mix gas and oil in a well-ventilated area away from combustible products.

Gas and Oil to Use in a 2-Cycle Poulan Pro Chainsaw
Poulan Pro currently offers chainsaws using 2-cycle engines. These types of engines use a fuel consisting of a gas and oil mixture.
If you are using a different brand of chainsaw, you must make sure you know the kind of engine being used. There are engines with 4-cycle engines being sold. These types of engines may require straight gas.
Don’t make the mistake of adding straight gas to a Poulan Pro 2-cycle chainsaw or you will end up ruining it and most likely have to buy a new one.
Straight gas runs very dry and will cause a 2-cycle engine to seize up and quit. Without oil added to the gas, the engine doesn’t get the lubrication it requires for internal parts to move freely.
Poulan Pro Chainsaws Use a Gas-to-Oil Fuel Mixture of 40:1 or 50:1
The 2-cycle engine on your Poulan Pro chainsaw has one fill port for gas and oil mixed at a 40:1 or 50:1 ratio. The ratio varies by model. The current Poulan Pro chainsaws require a 50:1 mixture while older models use a 40:1 ratio.
Check your operator’s manual for the type of oil required for your model Poulan Pro.
|Gas to Oil Mix||1 Gallon Gas||2 Gallon Gas||2.5 Gallon Gas|
|40:1||3.2 oz Oil||6.4 oz Oil||8.0 oz Oil|
|50:1||2.6 oz Oil||5.2 oz Oil||6.4 oz Oil|
Type of Gas to Use in a Poulan Pro Chainsaw
When selecting gas for your Poulan Pro chainsaw, always use fresh gas. When gas gets old, it begins to break down and become less combustible.
Gas with ethanol attracts moisture from the air to the fuel leaving behind a varnish in the fuel system. Gummy deposits will clog fuel components and prevent the carburetor from working sufficiently.
This can result in problems with your Poulan Pro chainsaw not starting, dying, or experiencing a loss of power.
Poulan Pro chainsaws 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 and E85. These types of fuel contain up to 15% and 85% of ethanol respectively. A low ethanol content or an ethanol-free fuel is best.
Type of Oil to Use in a Poulan Pro Chainsaw
Poulan Pro chainsaws require a premium 2-cycle oil that is ISO-L-EGD and JASO M345 FD certified. Poulan Pro offers 40:1 and 50:1 2-cycle engine oil.
Note: 2-cycle oil air-cooled engine oil is not the same as automotive engine oil or 2-cycle outboard oil. Do not use standard engine oil in your chainsaw.
Pre-Mixed Poulan Pro 2-Cycle Fuel
A pre-mixed fuel like TruFuel 40:1 Pre-Blended Fuel or 50:1 Pre-Blended Fuel that contains an ethanol-free fuel and oil ready to pour into the tank is a good option for fuel. It is convenient to have fuel sitting on the shelf ready when you need it.
Better yet, you won’t have to deal with the fuel problems caused by running ethanol-based fuel.
Add a Fuel Stabilizer to Your Poulan Pro Chainsaw
Because gas begins to break down as soon as 30 days after purchase, it’s important to only purchase the amount of gas you can consume within this time.
If you are unable to consume it within this timeframe, use a fuel additive like Sea Foam Motor Treatment or STA-BIL to help keep the fuel stable and reduce moisture.
I choose to add Sea Foam to all of my fuel for added insurance in case fuel sits around longer than it should. It can be hard to know exactly how much fuel I am going to go through.
How to Mix Gas for a Poulan Pro Chainsaw
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 (2.6 oz. per gallon of gas).
- Replace the cap.
- Gently shake the fuel and oil until they are mixed.
- Add to the chainsaw’s fuel tank.
Always mark your gas can with the type of gas or gas/oil mix in the can. Mistakenly adding the wrong fuel to a piece of equipment can damage it. You may be able to remember you mixed fuel in a certain fuel can, but someone else may not know.
