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.
What kind of gas does my chainsaw take?
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. Stihl offers 2-cycle oils made especially for Stihl chainsaws. Premium quality 2-cycle fuels provide protection for your engine.
Can you use regular gas in chainsaw?
A chainsaw uses regular unleaded gas but it needs to be mixed with the right oil . Most chainsaws use pre-mixed gasoline-oil. Oil is mixed in with the gas to lubricate the engine and prevent fouling.
Do all chainsaws use 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.
Are all chainsaws 2-cycle?
Chainsaw engines come as either 2-stroke or 4-stroke versions . Sometimes these are also referred to as 2-cycle and 4-cycle engines – it's the same thing.
What happens if you put 2-cycle oil in a 4-cycle engine?
4-cycle engines are usually made to closer tolerances so having oil mixed with the fuel can gum them up and cause overheating . As long as you only add oil to the 2-cycle machine's fuel, then you are fine.
What kind of gas does STIHL chainsaw use?
Use a minimum of 89 octane gasoline and always use fresh fuel. Only buy enough gasoline that you can easily use up within a two- month period. For air-cooled, two-cycle engines, use a quality mix oil that meets the engine manufacturer's recommendations.
What will happen if you put regular gas in a 2-cycle engine?
If you put straight gas in the tank, you may get to burn half of it, or you may just get to start the engine . With no oil mix in the fuel it will take oil from the base. In no time at all that oil will be depleted, and your bearings, and rings will starve for oil. Lock up is imminent, and a rebuild will be in order.
Does a Craftsman chainsaw need mixed gas?
The Craftsman 2.0 chainsaw, as with all gas-powered Craftsman saws, requires mixed fuel for combustion . This fuel combines gasoline and an engine oil, which lubricates the piston and crankcase during operation.
Does a STIHL chainsaw take mixed gas?
Using the right type of fuel is critical in the safe and efficient operation of your STIHL equipment. Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil . Knowing the proper way to mix your fuel is the first step in keeping it running strong and long.
Do Poulan chainsaws use mixed gas?

Can I use any 2 stroke oil in my chainsaw?
Modern two stroke chainsaws do not require generic brand oils to operate at temperatures and rpms that are comparable to those of generic brand oils. Our recommendation is to use only high quality two stroke oil designed for air cooled high performance engines when using your modern two-cycle engine.
How long can a chainsaw run on a tank of gas?
What is the runtime of a Chainsaw? Depending on the type and usage, you can expect a gas Chainsaw to run between 15 and 40 min before you have to fill it up again. Most battery-powered chainsaws have a run time of up to 2 hours, but there are high-capacity power packs that will last much longer.
What type of fuel does a Homelite chainsaw use?
The recommended fuel mixture is a 50-to-1 ratio of unleaded gasoline and two-cycle engine oil , and the manufacturer recommends the use of a two-cycle oil that contains fuel stabilizer to keep the mixture fresh if you are not using it immediately.
Do you mix gas and oil for a 2-stroke?
Two-stroke (or 2-cycle) engines require a mixture of fuel and oil be added to the fuel tank . This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
Are all Husqvarna chainsaws 2-stroke?
All Husqvarna chainsaws use the ratio of 50:1 , this means that for every gallon of gas you will use 2.6 oz. of 2 stroke engine oil. Even though your owner's manual may say 87 octane, always use 89, just to be safe, and to prevent “knocking” which could be damaging to your engine.
Are STIHL chainsaws 2-stroke?
2-stroke engines such as STIHL petrol Chainsaws run off a mix of petrol and engine oil. STIHL Chainsaws use a mixing ratio of 1 part oil to 50 parts petrol, which is 20 mls of oil per litre of petrol. If you are using any other brand please mix at 25:1 or 40 mls per litre.
Can you use motor oil for 2-cycle oil?
Can We Use Engine Oil Instead Of 2t Oil? There is no problem with that . If you were to use 2 stroke oil, you would use it in the same proportions. In order to maintain the lubricating qualities of the oil added to the fuel, too little can cause bearing and bore damage.
Is TruFuel better than gas?
TruFuel is made specifically for higher-revving, hotter-running 2-cycle engines. Pump gas is made for your car but can wreak havoc on a small engine. Pump gas and oil can leave carbon deposits and gunk in your engine and fuel line. TruFuel is cleaner, enhances equipment performance, and is better for your engine .

- If the older gas isn't contaminated, dilute it with fresh fuel for reuse (optional).
- Locate the nearest hazardous waste disposal in your area.
- Transfer gasoline to a government-certified container.
What happens if you mix too much oil in a 2 stroke?
Too much oil, and your engine may struggle to start or run, generate carbon buildup on engine internals, blow clouds of smoke and perform poorly in general .
What kind of gas goes in a 2-stroke engine?
Any fuel type between 87-octane and the 92-octane will work just fine depending on the type of motocross bike you own. If you own a 4 stroke, for example, the 82-octane works just fine, but for a 2-stroke, you should go for the ethanol-free higher octanes (92 and 93) because the lower octanes tend to detonate.
