The STIHL MS 151 C-E is a lightweight gasoline-powered chain saw with a low-emission, fuel-efficient engine. What sets it apart from other models, however, is its cutting performance. It features a new engine technology called the STIHL M-Tronic™, which can optimize engine power based on environmental conditions and the type of wood being cut. This means better performance when cutting branches and logs, but less gas consumption overall.

STIHL MS 151 C-E Vs MS 251

This is especially useful for people who work in areas with varying weather conditions (such as those who work outdoors or in forestry operations). Another aspect that sets this best Stihl chainsaw apart from others on the market today is its low weight (just 7 pounds) which makes it easy to handle even when using two hands to steady yourself while doing precision cuts like carving out doorways or making decorative shelves.


The MS 251 is the best chainsaw for homeowners. It’s more powerful than the MS 151 but less powerful than the MS 291, which makes it a great choice for anyone who doesn’t plan to use their chainsaw every day. For example: if you have a big property and do your own landscaping and firewood cutting, you’ll love its extra power over the MS 151.

The MS 251 is the most powerful of the two saws, but both are powerful enough to handle most home jobs. The MS 151 C-E is a bit lighter than the MS 251, and users will notice the difference when carrying the saw for long periods of time. The MS 151 C-E is slightly more fuel-efficient than the MS 251, which means you’ll be getting just as much work done with less fuel in your tank.

STIHL MS 151 C-E vs MS 251|Engine Displacement

The STIHL MS 151 C-E chainsaw is designed to be easy to use, but still has all the features that a more experienced operator wants. The MS 151 C-E has improved power and fuel efficiency, and an anti-vibration system for a more comfortable user experience. At 8.7 pounds, it’s light enough to carry around as you work. It also has a quick chain adjuster for easy changes when you need to replace or adjust your cutting chain.

The STIHL MS 251 is a professional quality chainsaw that offers the same ergonomic design as the MS 151 C-E with added features. The MS 251 has improved fuel efficiency compared to previous models, so it lasts longer and runs smoother with less effort.

The displacement of an engine will impact the amount of power it produces. Engines with larger displacements tend to produce more power and be heavier than smaller ones. In this article, we’ll be comparing two STIHL chainsaws: the MS 151 C-E and the MS 251. These chainsaws both have different engine displacements and therefore will perform differently in terms of power output. Note that we’ll be comparing the maximum engine displacements, not necessarily the actual displacements when you first use them (which may actually be different).

STIHL MS 151 C-E vs MS 251|Power output

It produces 50% less emissions (as compared to previous models) for a smaller impact on the environment. The MS 251 also features an advanced anti-vibration system for comfortable operation and the ErgoStart system for effortless starting. With two stroke engines, people can expect a higher performance and optimal torque with this product from STIHL.

The chainsaws are designed for comfortable handling and smooth operation. With its fuel efficiency, powerful cutting performance and low emissions, the STIHL MS 251 is ideal for demanding cutting jobs in medium-duty commercial use and firewood cutting. The STIHL MS 151 C-E is a high performance, fuel-efficient chain saw. It produces 50% less emissions (as compared to previous models) for a smaller impact on the environment. The MS 151 C-E also features an advanced anti-vibration system for comfortable operation and the ErgoStart system for effortless starting.

STIHL MS 151 C-E vs MS 251|Weight

The STIHL MS 151 C-E is a lightweight, fuel-efficient chainsaw that delivers professional performance. With the STIHL MS 251 chainsaw, you’ll get even more power, but with a weight that’s still easy to handle. Both of these high-quality chainsaws are designed to be comfortable enough for extended use and to run smoothly with low vibration levels. They both feature anti-vibration mounts between the engine and the front handle and an ergonomic handle design that reduces operator fatigue.

Plus, they both have a side access chain tensioner for quick chain adjustments. Where they differ is in their engine size and power output. The MS 151 C-E is equipped with a 33.8 cc engine while the MS 251 has a 50.2 cc engine. This means that the MS 251 will be able to take on cutting tasks slightly larger than what the MS 151 C-E can tackle, such as cutting 18″ logs versus 16″. It also means that the larger model produces more horsepower—2.7 hp for the STIHL MS 151 vs 3.9 hp for the STIHL MS 251—so it will be able to cut through wood faster than its smaller counterpart.

STIHL MS 151 C-E vs MS 251|Power-to-weight ratio

The STIHL MS 251 is a workhorse chainsaw that still has an easy-to-start engine. This saw’s high torque over a wide range of speeds makes it ideal for tough cutting jobs like felling small trees and bucking large diameter logs. It’s also perfect for pruning, thinning, and cutting firewood. Both the STIHL MS 151 C-E and the STIHL MS 251 feature the same length guide bar which means you can swap out your bar on one model if you have multiple chainsaws from the STIHL Homeowner line.

The STIHL MS 151 C-E and the MS 251 are both highly recommended in professional logging and forestry, but they each have their own unique set of features that differentiates them from each other. While the 151 C-E has a lower price point and weighs less, it also has a lower engine displacement and power output than the 251.

It’s just one less thing to worry about by eliminating pull-start resistance, saving you time and frustration. It also features our ErgoStart system for simplified starting, which reduces the needed pulling force by about 40%.

It works by compressing the spring when pulled slowly, so you can start it up with minimal effort. The MS 251 C-E includes our exclusive STIHL Quickstop® Plus chain brake system as well as STIHL Quick Chain Adjuster (B), allowing you to adjust your saw chain without tools.
