Engine displacement is important in determining how much fuel your chainsaw will consume while running. It’s important to note that this isn’t necessarily a comparison of what’s best out of these two chainsaws, but rather a comparison between them so you can make an educated purchase decision. The MS 171 has a slightly larger engine displacement than its counterpart, at 40.2 cc (1.6 kW) compared with 31 cc (1.3 kW).
The STIHL MS 171 chainsaw offers a powerful engine with 2.7kW of power output, which is more than adequate for most moderate jobs around the home or farm. The STIHL MS 151 C-E packs even more power into its engine, offering 3.0 kW of power output and making it ideal for more demanding tasks like cutting down trees or working in the field. Both models offer high torque at low speeds to ensure consistent reliability when working in the field or on construction sites.
The two machines are very similar in terms of weight. The STIHL MS171 weighs 14.1lbs, while the MS151 C-E weighs 13.2lbs.
The STIHL MS 171 has a power output of 1.3 kW and a weight of 4.3 kg, resulting in a power-to-weight ratio of 0.302 kW/kg. On the other hand, the STIHL MS 151 C-E has a power output of 1.05 kW and a weight of 2.8 kg, resulting in a power-to-weight ratio of 0.375 kW/kg. Therefore, the STIHL MS 151 C-E has a slightly better power-to-weight ratio than the STIHL MS 171 due to its lighter weight and slightly lower power output.
Sound pressure level
The first difference between these two Stihl chainsaws is their sound pressure level. The MS 171 has a sound pressure level measurement of 102 dB(A), while the MS 151 C-E has a slightly higher rating of 103 dB(A). While this difference may seem insignificant, it can actually have a major impact on your ability to operate the saw comfortably.
Sound power level
Although the MS 171 and MS 151 C-E are both chainsaws, there are some differences in the features. The primary differences between them include: Sound power level. The MS 171 has a sound power level of 93 dB(A), while the MS 151 C-E has a sound power level of 89 dB(A). This means that the MS 171 is louder than the MS 151 C-E.
However, this isn’t necessarily a bad thing as it can be used as an advantage when cutting because you’ll be able to hear where your cuts are going and avoid hitting any objects or people that might be in your way.
Vibration level left/right
In general, the STIHL MS 171 is designed to have reduced vibration levels compared to the MS 251 C-E. The MS 151 C-E has STIHL’s anti-vibration system, which reduces the amount of vibration that is transmitted to the user’s hands and helps to decrease operator fatigue.

The STIHL MS 171 chainsaw uses 3/8″ saw chains, which means that the distance between any three consecutive rivets is 1 inch. The STIHL MS 151 C-E chainsaw uses 1/4″ Picco Micro™ saw chains, which means that the distance between any three consecutive rivets is 0. 5 inches.
STIHL Oilomatic saw chain type
The STIHL Oilomatic system is an oil injection system that provides consistent lubrication of the bar and chain, and is designed to reduce maintenance intervals. It also helps to extend the life of your saw and make it easier to start. The MS 171 features an automatic oil pump that delivers the correct amount of oil to the bar and chain during operation.
