STIHL MS 170 vs MS 151 C-E|Engine Displacement

MS 170 vs MS 151 C-E

The STIHL MS 170 and STIHL MS 151 C-E both offer a powerful engine to make light work of cutting wood. Both chainsaws are equipped with Easy2Start, which allows you to get the chainsaw started with minimal effort. They also each have a 2-MIX engine, which is designed to reduce emissions while also improving fuel economy. While they share many of the same features, there are some differences between the two chainsaws.

One key difference comes in their engine displacement. While the MS 170 has an engine displacement of 30.1 cc, the MS 151 C-E has an engine displacement of 29.5 cc. This difference may not seem like much, but it can affect how hard each chainsaw works and how long it lasts before needing a tune up or replacement parts. Another key difference is that the fuel tank capacity on the MS 170 is 14.9 oz., while the fuel tank capacity on the MS 151 C-E is 13.

STIHL MS 170 vs MS 151 C-E|Power output

The STIHL MS 170 is a medium-sized saw that has a power output of 1.7 HP. This means it will be able to handle most jobs around the house or in the garden without any issues. The STIHL MS 151 C-E, on the other hand, has a power output of 2.

The higher power output means that the MS 170 is capable of cutting more efficiently than the MS 151 C-E because it can cut through thicker objects more quickly while using less energy in the process.

STIHL MS 170 vs MS 151 C-E|Weight

The STIHL MS 170 and the MS 151 C-E are two of the most popular handheld chainsaws on the market today. Both are great machines for cutting wood or clearing brush, but there are some key differences between them. The MS 170 weighs 6 pounds, while the MS 151 C-E weighs 4 pounds. This means that if you’re going to be using your saw for extended periods of time, you may want to consider the lighter weight of the MS 151 C-E.

STIHL MS 170 vs MS 151 C-E|Power-to-weight ratio

The MS 170 has an engine displacement of 140cc while the MS 151 C-E has an engine displacement of 125cc. The larger engine displacement on the MS 170 allows it to produce more torque at lower RPMs than its smaller cousin. This means less vibration during operation and better performance when cutting hardwoods like oak or hickory that can be difficult for smaller engines to handle. 

The STIHL MS 170 has a power-to-weight ratio of 1.1 HP per pound, which means that it can blow leaves at an impressive speed for such a light machine. The MS 151 C-E has a power-to-weight ratio of 1.2 HP per pound, which makes it just as powerful as the MS 170 in terms of blowing power alone.

STIHL MS 170 vs MS 151 C-E|Sound pressure level

STIHL chainsaws are useful entry level chainsaws for those who want to cut small branches or clear wood around their home. Like the MS 170, the MS 151 C-E is also a lightweight and affordable chainsaw. The difference between the MS 170 and the MS 151 C-E is that the latter has reduced emissions of hydrocarbons and nitrogen oxides, making it more environmentally friendly. The STIHL MS 170 has an engine power of 1.5/1.1 kW/bhp, which means that it can be used to clear branches and small trees with a diameter of up to 35 cm.

It also comes with an economical 2-MIX engine and an Ematic chain lubrication system which ensures reliable lubrication of the bar and chain and reduces oil consumption by 50%. 

STIHL MS 170 vs MS 151 C-E|Sound power level

The sound power level is one of the crucial factors to consider when choosing a product. The higher the value of sound power level given by the decibel (dB), the noisier it will be. The MS 170 model has a sound power level of 105 dB while MS 151 C-E has a lower value at 103 dB. Power Source The MS 170 model requires fuel while MS 151 C-E is powered using an electric cord.

If you’ve been thinking about upgrading your chainsaw, or if you’re a new user looking to buy a gas chainsaw for the first time, you may be wondering what the difference is between the STIHL MS 170 vs MS 151 C-E models. While both chainsaws are designed for occasional wood-cutting tasks around the home, and both are also lightweight and easy-to-use, there are some key differences between these two models that may help you decide which is better for you. One of the most notable differences between the MS 170 and the MS 151 C-E is their vibration levels. In fact, one of the main reasons that STIHL developed the MS 151 C-E was because they wanted to reduce operator fatigue.

The vibration levels on this saw have been reduced by almost half compared to other models in its class. Yet it still retains its power and performance, which makes it an especially good choice for people who will be using their chainsaw frequently during long periods of time. The carburetor preheating system on this model is also a big factor in reducing vibrations by allowing easier starting in cold weather.

In contrast, the STIHL MS 170 has a maximum vibration level of 6.5.

STIHL MS 170 vs MS 151 C-E|Saw chain pitch

Both chainsaws come with a 16-inch carbide steel blade but they have different pitch sizes: 0.325 on the STIHL MS 170 and 0.404 on the STIHL MS 151 C-E. In general, larger pitch sizes mean better performance and durability but at a cost of added weight and vibration during use as well as increased fuel consumption because more energy is required to spin.

STIHL MS 170 vs MS 151 C-E|STIHL Oilomatic saw chain type

These two chainsaws are very similar and because of that, many people get confused. They are both light weight saws, with a lot of power and they are affordable. The MS 170 is a great saw for the homeowner who needs to cut up some firewood and do limbing on smaller trees. It is also good for small clean up jobs on the property. Even though it is a light weight saw, it can tackle some pretty big tasks (just not as efficiently as some other chainsaws).

The MS 151 C-E is a very versatile saw that can be used by homeowners, professional arborists or tree care companies. It can be used for trimming small branches, cutting trees into logs and even cutting down large trees.

STIHL MS 170 vs MS 151 C-E|which is more better

The STIHL MS 170 and the STIHL MS 151 C-E are both chainsaws, however, they have very different uses. The MS 170 is a commercial grade saw that is designed for larger wood cutting jobs. It is a professional-level chainsaw that will not be put through the same rigorous conditions as the MS 151 C-E which is designed for homeowners to use around their property. STIHL MS 170 Review The STIHL MS 170 has a lot of power behind it. It comes equipped with an Oregon bar and chain combination as well as a 33 cc engine. This will allow you to cut through most types of wood easily without much effort at all. The kickback from this saw is minimal and there are no vibrations felt throughout the entire machine while in use.


Both the MS 151 C-E and MS 170 are a good choice for homeowners, but the MS 170 has slightly better performance due to its wider range of adjustments, especially when it comes to square cutting angle.
