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

oils made especially for Stihl chainsaws. Premium quality 2-cycle fuels provide protection for your engine.
Do chainsaws take regular 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 mix oil with gas for chainsaw?
Your manual will tell you the fuel mixture you need. Many gas-powered chainsaws run on a 40:1 mixture of gasoline and 2-cycle engine oil. Other chainsaws run on a 50:1 mixture of gas and 2-cycle engine oil. Some older models use a 30:1 ratio.
What happens if you run straight gas in a 2-stroke?
Q: What would happen if you put regular unmixed gas in a 2 stroke engine? A: It soon seizes from lack of lubrication and becomes a NO stroke engine.
What causes a chainsaw to seize?
The reason why a chainsaw seizes is that the lack of lubrication on the piston. When the piston got stuck due to lack of lubrication, it seized the chainsaw engine up. In some cases, the same can happen if the chainsaw’s carburetor is too lean or if it was not functioning properly.
How much oil do you put in a chainsaw gas?
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.
Is a chainsaw 2 or 4 stroke?
Chainsaw engines come as either 2-stroke or 4-stroke versions. Without going deep into the mechanics of how chainsaw engines work, a 2-stroke engine produces power for every two strokes of the pistons while a 4-stroke engine requires four strokes to produce power.
Can I use 4 stroke oil for chainsaw?
Chainsaw is either two stroke oil or chain oil. Dont use either of these as a lubricant oil in an engine as one is designed to burn and the other has anti fling qualities (yes really!) If its a Stihl use good quality Stihl stuff. If your mower has an oil filler cap on top, it’s a 4 stroke.
What happens if I put too much oil in my 2-stroke?
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit.
Will two-stroke fuel ruin my lawn mower?
If your lawnmower has a 2-stroke engine, it needs mixed gas, so you are ok. If your lawnmower has a 4-stroke engine and uses mixed gas, it can cause the engine to choke, overheat, and cause the engine to smoke.
How much does it cost to fix a chainsaw?
THE AVERAGE CHAINSAW SERVICE IS $100 TO $125 If we can find ways to help save you money, we will suggest them to you. If we do not feel it is worth repairing, we will tell you so.
Why is my chainsaw chain not turning?
If your chainsaw blade will not rotate, the chain may be tensioned too tight. If the chain is too tight, the blade may not spin when the throttle is engaged, which can cause damage to the clutch or other associated parts. Keep in mind that the tension of the chain will change with heat.
Can I use 2 stroke oil for chainsaw?
There is two stroke oil for air cooled engines and two stroke oil for water cooled engines. Two stroke oil for water cooled engines is not designed to operate at the higher temperatures of an air cooled engine such as a chainsaw engine.
What oil is best for chainsaw?
Petroleum-based bar oil has been the standard for chainsaws. Lightweight oil is used in winter and heavier oil in summer.
Is a chainsaw a two stroke engine?
These days, you’ll find two-stroke engines in all kinds of gas equipment, such as chainsaws, string trimmers, hedge trimmers and leaf blowers, largely because two-stroke engines have fewer moving parts, generate less heat and are in many ways more efficient for their size.
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?
Many STIHL hand-held power-tools use 2-stroke combustion engines but some chainsaws, hedge trimmers, grass trimmers and other tools use engines with 2-MIX technology – so what’s the difference and what does it mean for you when you are using the tools?May 14, 2020.
Do Electric chainsaws need bar oil?
Electric chain saws derive their power from an electric source, so they don’t need fuel to run. Electric chain saws don’t require this added oil, but the bar and chain do need to be properly lubricated. Electric chain saws use the same type of lubrication for the bar and chain as gas-powered chain saws.
How tight should a chainsaw chain be?
A properly-tensioned chainsaw chain should still be just a little loose on the chainsaw guide bar, but the chain needs to be tight enough that you can’t pull the drive links out of the bar nose.
Is chainsaw oil the same as lawn mower oil?
Any two-stroke motor oil made for air-cooled engines, such those in chainsaws, water pumps and weed eaters, will work perfectly in your two-stroke lawn mower engine.
What does white smoke on a 2 stroke mean?
White smoke exiting the exhaust pipe after the engine has warmed may be a sign that coolant is burning in the combustion chamber. The root of this problem is typically a leaking cylinder head gasket or o-rings.
How long can a 2 stroke sit?
Opinions on how long a container of pre-mixed 2 stroke fuel will last for varies significantly, some say it is only good for 3 – 4 weeks and others up to 2 – 3 months. In my experience it depends on the motor, but all motors will perform best with a full tank of freshly mixed fuel. “Fresh is best!”Jul 29, 2020.
Why is my 2-stroke engine smoking?
When a two stroke engine starts to smoke, it’s caused by burning oil, clogged air filters, damaged head gaskets, or failed piston rings. However, new mowers often have excess lubrication that needs to be burned off, hence the bit of smoke you might notice.
