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.
Before I show you how to mix chainsaw fuel, I wanted to make you aware that I have several chainsaw buying guides to help you find the perfect tool for your needs. Additional Tips on Mixing Chainsaw Gas.Never mix gas and oil in the tank of the chainsaw. I hope you enjoyed this post on how to mix chainsaw gas.
The larger number represents the amount of gasoline, while the smaller is the amount of oil needed. If you are treating 1 gallon of clean unleaded gasoline, a 50:1 ration translates to 2.5 ounces of two-cycle oil, while preparing a 40:1 blend calls for 3 ounces of oil. It’s best to use the premixed gas within a few days and to shake it well anytime it’s been sitting for a while to redistribute the oil completely into the gas.
what fuel do chainsaws take Related Question:
What fuel does a chainsaw use?
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.
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.
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.
What fuel does a STIHL chainsaws use?
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.
Can I use cooking oil for chainsaw?
Effective – Vegetable oils have natural properties including good lubricity, resistance to shear, a high flash point, and a high viscosity index. These qualities lend themselves to chain lubricant requirements similar to petroleum-based chain oils, and do not contribute to chain or bar wear over time.
What happens if you run a chainsaw without bar oil?
Without lubricant, the speed at which the chain moves over the chainsaw bar can cause some serious friction. A slowed-down chain and excessive fuel burning mean there’s a lot of friction between your bar and chain, which means a lot of heat is being produced that could do major damage to your saw.
Do Electric chainsaws need bar oil?
Electric chain saws derive their power from an electric source, so they don’t need fuel to run. Most gas chain saws require a premixed gas-and-oil fuel to operate properly. Electric chain saws don’t require this added oil, but the bar and chain do need to be properly lubricated.
Does chainsaw need oil?
You want lubrication of the actual chain against the bar. You don’t want to chain to burn – which is what might happen if there’s too much friction. Without oil, it causes frictional force on the motor in the chainsaw as well.
Does a chainsaw need engine oil?
To run properly, all chainsaws need two types of oil for different jobs. The first is engine oil. The chainsaw shown here has a two-stroke engine, so it needs two-stroke engine oil mixed with the fuel to help cool and lubricate the moving parts inside the motor.
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.
Can I use 10w30 for chainsaw bar oil?
As a matter of fact, you can actually use regular 10w30 motor oil on a chainsaw as one of the alternatives in case you don’t have bar and chain oil. That’s because 10w30 oil has enough thickness and viscosity that will allow it to withstand the friction that is happening whenever you are using a chainsaw.
