Benefits of a Gas Chainsaw Over Electric Models
If you’re trying to decide between a gas and an electric chainsaw, it really comes down to power, mobility, and how much work you need to get done. Gas chainsaws are the go-to choice for professionals and anyone dealing with big jobs.
First off, they pack a serious punch. Gas chainsaws have way more power than electric ones, making them perfect for cutting through thick logs or felling large trees. You’re not going to struggle with tougher wood like you might with a smaller electric model.
Then there’s mobility. No cords, no worrying about battery life—just fuel up and go. If you’re out in the woods or working on a remote property, you don’t want to be stuck hunting for a power source or swapping out batteries every half hour. Of course, they do require more maintenance, and they’re louder than electric saws. But if you need raw cutting power and all-day reliability, gas is the way to go.
How Does a Gas Chainsaw Work?
A gas chainsaw runs on a two-stroke engine, which means it burns a mix of petrol and oil to power the chain around the bar. When you pull the starter cord, it gets the engine going by sparking the fuel mixture inside the cylinder.
The engine drives a clutch, which then spins the chain around the bar at high speeds. That’s what lets you slice through wood with ease. But it’s not just brute force—there’s also a chain brake for safety, a carburetor to control the fuel mixture, and an exhaust system to vent out gases. And here’s something a lot of beginners don’t realise: keeping the chain properly lubricated is key. The bar and chain oil keeps everything running smoothly, reducing wear and preventing overheating.
What Fuel Should I Use in a Gas Chainsaw?
Most gas chainsaws run on a mix of petrol and two-stroke oil. And no, you can’t just pour regular petrol in and call it a day—you need to mix in the right amount of oil to keep the engine lubricated.
Typically, the ratio is 50:1 or 40:1, depending on the chainsaw model. That means 50 (or 40) parts petrol to 1 part oil. Your chainsaw’s manual will tell you the exact mix you need.
Also, go for unleaded petrol with an octane rating of 89 or higher. Low-quality or old fuel can cause engine issues. If you’re not using the saw often, it’s a good idea to use a fuel stabiliser to keep the mix fresh.
And here’s a tip: mix the fuel in a separate container first, not directly in the saw. That way, you get an even blend and avoid engine damage from bad mixing.
