A: Our units run on 87 octane regular unleaded gasoline. You can use gasoline which is blended with a maximum 10% alcohol. Never use E85 or diesel fuels. Remember to use fresh gasoline and to mix it with the recommended 2-cycle oil.
If Poulan bar and chain oil is not available, use another brand of bar and chain oil. The oil retained on the chain protects the bar and chain from overheating caused by friction. If the chain brake is disengaged and the chain does not turn; turn off the saw, then check the drive links on the chain, the bar groove and the sprocket nose on the bar.
All gas-powered chainsaws need gas mixed with oil in order to work correctly. Mixed gas refers to combining the gas that some chainsaws use with oil. Only the gas-operated chainsaws take mixed gas, because they are the only ones actually running on gas.
Only mix enough fuel to last you one to three days at a time; this limit keeps the fuel fresh and minimizes the risk of any buildup. If you find mixing to be too time-consuming or annoying, Stihl does offer customers other options to run their chainsaws, such as Stihl MotoMix, a pre-mixed, high-performance fuel that is ready to use straight away, eliminating the need for measuring, shaking and storing. Whether you purchase a pre-mixed fuel or mix your own, following the correct ratio can keep your chainsaw working properly and keep it working for years.
Always mix gasoline and oil in a clean fuel container, not in the chainsaw’s fuel tank. 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. Read your product instruction manual for additional information on fueling and fuel mixtures.
A chainsaw uses regular unleaded gas but it needs to be mixed with the right oil. Chainsaws that take regular gasoline can also be started on a mixture of gas and oil but require more preparation before use. Mixed gas varies in ratios because each chainsaw has its specifications that you need to look at for you to figure out how much pre-mix oil and gasoline you should be using for your saw.
what gas do chainsaws use Related Question:
Do chainsaws use 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.
What gas should I use in my chainsaw?
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.
Can I use 87 octane in my chainsaw?
STIHL recommends that customers use a minimum of 89 octane fuel. 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.
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.
Can 93 octane go in chainsaw?
Hi Octane gasoline does not run hotter, as most people think. It actually runs cooler. Using 93 in the Poulan, won’t hurt it, but it won’t help it either. In fact it may cause the exhaust port and muffler screens to carbon up quicker, due to the lowered temperature.
What happens if you mix too much oil in a 2 stroke?
Using the proper oil-to-gas ratio is important, but if you’re off, it’s better to mix too much oil into your engine than mixing too little oil. Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power.
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.
What is the best fuel for two stroke engines?
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.
Should I run non ethanol gas in my chainsaw?
However, when you’re using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
HOW LONG CAN 2-stroke gas 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!”
HOW LONG CAN 2-stroke fuel be kept?
Two- stroke oil will last for a couple of years when it is not mixed with petroleum. Once mixed with petroleum we would not recommend keeping for more than 3-4 months in a sealed air tight approved storage container.
What happens if you put premix in a 4-stroke?
Running premix in a 4-stroke wont hurt it at all. It wont gain you anything, but it wont hurt it either. As far as what ratio to mix the gas at, honestly, it doesnt really matter.
What happens if you put 4 cycle gas in a 2-cycle engine?
When you used the 4 cycle gas, there was no much needed oil mixed with the gas. There may be a small chance the engine has not seized, it may start again, but the life of the engine has been greatly reduced. Show activity on this post. As Jack said, you almost certainly did permanent damage to the motor.
Can you use mixed gas in a car?
Yes, you may pour the unused fuel mixture into your car, provided you don’t fill the tank with the stuff. A couple gallons, if diluted by a tank-full of gas, will do no harm.
Is premium gas really worth it?
Recommended: When your owner’s manual (or the inside of the gas door) recommends premium you can still run your car on a lower grade fuel. For cars that merely recommend it, premium gasoline may very slightly improve performance (increased horsepower) and fuel economy, according to a November 2017 study from AAA.
