unleaded gasolineunleaded gasoline with a minimum octane-rating of 89 (mid-grade) and maximum ethanol content of 10% (E10). Never use E15, E30 or E85 in the engine as this will damage the engine and most likely void manufacturer warranties.

What kind of gas does a chainsaw need?
Unleaded gasoline
Unleaded gasoline with a minimum octane rating of 89 is recommended. A lower octane can cause some issues, such as increased engine temperature, increased piston seizures, and engine damage.
Does a chainsaw take regular gas?
Chainsaws use regular gas but are always mixed with suitable engine oil. Most gas chainsaws use a two-stroke engine that requires a mixture of gasoline and engine oil.
Do chainsaws use 2-stroke fuel?
These days, you’ll find two-stroke engines in all kinds of equipment, such as chainsaws, grass trimmers and hedge trimmers, largely because two-stroke engines have fewer moving parts, generate less heat and are in many ways more efficient for their size.
Is a chainsaw 2 or 4-stroke?
Chainsaws that run on gasoline all have 2-stroke engines, except some STIHL chainsaws that have a hybrid engine that is essentially 4-stroke, but still uses the same petrol-oil mix as 2-stroke engines. There are some very good reasons for all of this, and in this article I’m going to talk about them in detail.
Can I use 87 octane in my chainsaw?
Both brands of pro saws are designed to burn fuel rated at 89 octane or higher. Most regular grade fuel has an octane rating of about 87. This is not enough. We also don’t recommend the use of high octane aviation grade fuel.
Do all chainsaws need mixed gas?
But chainsaws are not like a regular car or motorcycle with a 4-stroke engine – they need a mixture of gas and oil to run. But do all chainsaws take mixed gas? Yes. All gas-powered chainsaws need gas mixed with oil in order to work correctly.
Does a chainsaw need mixed gas?
Nearly all gas chainsaws require a gasoline and oil mixture for their fuel. Chainsaw engines require a premixed fuel to keep them running at the proper temperatures. The oil that’s added to the fuel lubricates the piston and crankshaft, but it also keeps the engine cool enough to keep running.
Do you have to mix gas and oil for a chainsaw?
The fact is, most chainsaws are built with 2-cycle (or 2-stroke) engines which require a mixture of fuel and oil to run. Oil is mixed with gasoline (i.e. petrol) so that it can lubricate the internal parts of the engine while it operates. Without oil in the fuel tank, the internal components would seize up.
Can you put 2-stroke oil in a chainsaw?
No, you can’t use any 2-stroke oil in your chainsaw. Some 2-stroke oils are built for motor oils, and this might damage your chainsaw. Also, 2-stroke oils for an air-cooled engine are different from a water-cooled engine.
Is 2-cycle and 2-stroke the same?
In a 2 Cycle engine this is done in 2 piston strokes (one up and one down the piston cylinder). The Industry and the market generally use the term 2 cycle and 2 stroke interchangeably.
How much oil do I put in a 2-stroke chainsaw?
How Much and How to Mix It. The general ratio for most two-stroke chain saw combustion engines is 50:1, though some manufacturers recommend 40:1. The larger number represents the amount of gasoline, while the smaller is the amount of oil needed.
Can I use 93 octane in my chainsaw?
If a customer chooses to use a 91 or 93 octane fuel, no damage to the engine will result. However, using an 87 octane fuel could lead to serious engine damage. In recent years in different parts of the world and in this country, ethanol has been added to the fuel.
Do STIHL chainsaws take regular gas?
Stihl chainsaws require an 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 a gasoline that has a greater ethanol content of 10% like those sold as E15, E30 and E85.
What octane is regular gas?
Chapter 7: Fueling Your STIHL Chainsaw
Will a chainsaw run with straight gas?
If straight gas is used, it can damage and ruin the piston and crankcase within a minute, as the gas doesn’t take long to burn out these sensitive parts. Drain the tank immediately into a separate fuel container.
What happens if you run straight gas in a 2-stroke?
Without lubrication, it’ll cause high friction, causing heat and causing metal filings from the piston rings knocking around, and losing a seal. In a way, oil counteracts all of these. If it’ll still turn over, flush the fuel, and put in the correct mixture of petrol and oil.
Do you put oil in gas in a chainsaw?
Quote from video: Until the saw keeps. Running. So the very first few times i'm going to put the gas in you'll notice it's going to start smoke and die.
Does a STIHL chainsaw take mixed gas?
In the Mix
All STIHL gasoline-powered equipment uses a 50:1 gas and oil mixture.
How much oil do I put in a 2-stroke chainsaw?
How Much and How to Mix It. The general ratio for most two-stroke chain saw combustion engines is 50:1, though some manufacturers recommend 40:1. The larger number represents the amount of gasoline, while the smaller is the amount of oil needed.
Are STIHL chainsaws 2-stroke?
2-stroke engines such as STIHL petrol Chainsaws run off a mix of petrol and engine oil.
