I’ll also discuss the pros and cons of purchasing either chainsaw, helping you reach a well-informed decision. So, keep reading till the end to select the perfect model that suits your needs in today’s Echo CS 310 vs Stihl MS 170 review!

Echo CS310 VS. Stihl MS170: Which Is the Winner?

The Echo CS310 is a compact yet powerful chainsaw with an 8.8 lbs weight, a 2-stroke 30.5 cc engine, and an i-30 starter system. On the other hand, the Stihl MS170 is a lightweight cutting machine with 8.6 lbs of weight and a 2-MIX 30.1 cc engine.

These two chainsaws are pretty different in terms of their features and functionality. Let me break each difference down for you so you can figure out which one of these Echo and Stihl models is best for what you need. Here are the main things that set them apart: 

Size

The Echo CS310 weighs 8.8 lbs excluding the chain and guide bar weight. On the other hand, the Stihl chainsaw MS170 weighs slightly less than the CS310 at 8.6 lbs, excluding the equipment weight. This makes it more compact and lightweight. 

Engine Power

The CS310 model features an air-cooled 2-stroke engine with a single cylinder that delivers 1.86 hp and 30.5 cc displacement. An air-cooled 2-stroke engine with a single cylinder has a small and lightweight design. It sucks in a mix of fuel and air, then compresses and ignites it to produce energy. 

That power drives the crankshaft while the engine stays cool because air flows over it and keeps it from overheating. In comparison, the MS170 comes also comes with a Stihl air-cooled 2-stroke engine with a single cylinder, producing 1.7 hp and 30.1 cc displacement. 

However, the CS310 model is clearly a winner regarding engine power, which translates to an excellent power-to-weight ratio. Regarding the RPM of Echo CS310 and Stihl MS170, the former delivers a max 12,500 RPM, while the latter produces 14,000 max RPM. You can calculate the rpm using our latest chainsaw chain speed calculator though!

The higher max RPM of the MS170 variant also means it provides faster cutting through wood. In addition, the CS310 model has an idle speed of 3,200 RPM, while the MS170 delivers a 2,800 RPM idle speed. 

Having a higher idle speed of 310 model keeps the chain spinning even when you’re not using it, which can be handy. But, on the flip side, it also means the 310’s engine gets hotter compared to the MS170’s engine. 

Starting System

The Stihl MS170 has a Single-Lever Master Control for start, choke, throttle, and stop. But, when it comes to starting, you’ll have to manually pull the starter rope, which is easy but tricky if the chainsaw’s cold. 

On the other hand, the CS310 comes with a digital ignition and an i-30 Starter System. It’s an automatic recoil starter that rewinds the rope after starting the engine. So you don’t have to rewind it each time manually. 

The system reduces the effort you need to pull the starter cord by 30%, even when the cutting machine is cold, or the weather is cold. So, the starting system of the 310 variant is clearly the winner here.

Fuel Capacity

The Echo CS310 and the Stihl MS170 variants have an 8.5 oz fuel capacity. However, 170 wins in the fuel-efficiency department. Its 2-MIX technology makes it fuel-efficient by 20% and reduces emissions by 50%. 

The technology also complies with strict EU Stage V emissions regulations. So, it’s undoubtedly an advantage, especially if you are cutting in areas with stringent emission rules.

Oil Capacity and System

The Echo CS310 has an 8.8 oz chain oil capacity, while the Stihl MS170 features a 4.9 oz oil capacity. This means the CS310 has some serious advantages over the 170 model. Since it also has a higher chain oil capacity, it can run longer without refilling. 

Moreover, it features an automatic clutch-driven oiler that only lubricates the chain when it’s moving, so there’s less oil wastage. This system keeps the chain working smoothly by providing the right amount of oil exactly when needed. 

Carburetor

The Stihl MS170 carburetor features an IntelliCarb Compensator, which automatically adjusts the air/fuel ratio when the air filter clogs up. It works by using air from the clean side of the filter to regulate the fuel flow.

As the airflow lessens due to a dirty filter, the IntelliCarb system minimizes the fuel flow to the carburetor accordingly. This ensures that even when the filter is partially blocked, the engine will keep running smoothly at the right RPM. 

On the other hand, the Echo CS 310 carburetor comes with a purge pump and a Butterfly-Valve Diaphragm. When you’re not using the cutting machine, the purge pump helps eliminate air from the fuel system. 

This is important because it stops the fuel from evaporating and clogging the carburetor. When you pull the throttle grip, the butterfly valve opens up, letting more air into the carburetor. This increases the fuel-to-air ratio, giving your chainsaw more power.

Air Filter

Keeping your chainsaw engine clean from dirt and debris is super important, and that’s where regularly cleaning and maintaining the air filter comes in. 

Now, the Echo CS 310 has an advantage here. It’s got a tool-free access air filter cover, which means you can quickly and effortlessly remove it when you need to replace or clean the filter. 

This saves you loads of time and effort, ensuring your chainsaw always performs at its best. But the MS170 doesn’t have this handy feature. You’ll have to get your tools out and manually remove the filter cover when it’s time to do some maintenance.

Guide Bar Type

The Stihl MS170 boasts an Ematic guide bar that reduces oil consumption by 50%. There are two ramps in the guide bar rail that control the oil flow and direct the lubrication to the chain drive links. 

Combined with Stihl’s Oilomatic chain, it lubricates the bar and chain, depending on what you’re doing. This helps prevent excessive wear and tear, making the bar and chain last longer without wasting too much oil. 

In contrast, the Echo CS310 variant has a Double-Guard 91 bar with no feature to reduce oil consumption. However, it has a safety feature to minimize kickback.

The Stihl chainsaw bar has two rails that run along its length and prevents the chain from getting stuck or jumping off the bar. This safety feature makes the CS310 a better option, especially if you don’t have much experience with chainsaws.

Noise Level

The Stihl MS170 makes more noise with a sound power level of 111 dB and a sound pressure level of 100 dB. On the other hand, the Echo CS310 is a bit quieter, generating 107.7 dB of sound power and 97 dB of sound pressure. So, if you like a quieter cutting experience, the CS310 is the right choice.

Pricing

The Stihl MS170 best price you can get with a 16-inch bar is $299.99, while the Echo 14-inch chainsaw CS-310 costs $219.99.

Note: Prices may vary depending upon the marketplace you want the chainsaw models to order from

Warranty

The CS310 Echo chainsaw offers 5 years of consumer warranty and 1 year of commercial warranty. On the other hand, the MS170 Stihl chainsaw provides 1 year of consumer warranty and 3 months of commercial warranty.
