STIHL MS 231 is designed for lighter work around the house or job site. It has a lower weight of 7.8 lbs., which makes it easier to handle for less experienced users. Its low weight also allows you to cut for longer before needing to refuel as well.

STIHL MS 231 Vs MS 251 C-BE

On top of all that, it has an electric starter as opposed to a pull start as other chainsaws do! The Stihl MS 251 C-BE was built with professional users in mind who need something more powerful than what an average homeowner would need. It has a higher weight at 8.5 lbs., but offers greater power and cutting speed than the 231 does. It also features a semi-auto oiling system that keeps your chain lubricated while you’re cutting through logs and branches without having to stop every.


The MS 251 C-BE is a powerful and fuel-efficient chainsaw that features a side access chain tensioner and toolless fuel and oil caps for quick refills. This chainsaw has a compact, ergonomic design with excellent balance for easy handling and comfortable operation. The MS 251 C-BE also features our long-life air filter system with pre-separation and professional anti-vibration technology for increased comfort.

STIHL MS 231 vs MS 251 C-BE|Engine Displacement

Most consumers looking to buy a chainsaw are not looking to purchase a professional tool. They are looking for something they can use on the occasional project, around the home and farm. The MS 231 is an ideal choice for this situation. It shares many of the same components as the 251, with a lower price tag.

The MS 231 has a smaller engine displacement than the MS 251 C-BE. This results in less power output by the saw. The difference in engine size is probably not noticeable to most consumers, and will not affect the saw’s ability to cut through the wood when properly maintained and lubricated. The price difference between these two models is relatively small, which may be enough to entice some people who want more power from their saws.

Plus, both saws have a side-access chain tensioner for easy adjustment of the chain, an anti-vibration system, a side-mounted chain adjuster, an automatic chain oiler with an oil level view window, an integral lock-out switch to prevent accidental starting, an adjustable rear handle and a large trigger switch with soft grip handles.

Despite their many similarities, there’s one notable difference between these two chainsaws: the MS 251 C-BE has Quick Chain Adjustment (B) which has been combined with the tool-free fuel cap (E) for a safe and convenient chain tensioning and bar oil filling. Simply pull the lever up while pressing down on the sprocket cover to loosen the bar nuts. This allows you to remove the cover without tools and adjust the chain tension by hand. There’s no need to worry about removing your gloves or using special.

The MS 231 is a lightweight, well-balanced chainsaw that’s perfect for those who are looking to make quick work of cutting firewood and felling small trees.

The MS 251 also has a more efficient engine with more advanced technology.

STIHL chainsaws are world-class and offer the best power-to-weight ratio of any chainsaw on the market. Whether you’re a homeowner, farmer, or landscaper, we have a STIHL chainsaw that’s just right for you!

STIHL MS 231 vs MS 251 C-BE|Saw chain pitch

The STIHL MS231 and the MS251 are both chainsaws that are ideal for homeowners who don’t have a lot of experience with chainsaws. Both are affordable, easy to use, and capable of cutting through small to medium-sized trees. The differences between these two models are minimal, but they do exist. The MS231 has a 16″ bar and chain while the MS251 has a 20″ bar and chain. The larger bar offers more cutting power and can handle larger trees than the MS231 can. It also comes with an automatic oiler so you don’t have to worry about keeping it lubricated during use.

The STIHL MS 231 and MS 251 C-BE are both great saws. The 231 has many more features on it than the MS 251 C-BE, but if you’re looking for a saw that will last you a long time and be comfortable to use, then I would recommend the MS 251 C-BE. The STIHL MS 231 has a longer bar (1-day vs 0.8-day), which means that it can handle bigger logs than the MS 251 C-BE. This is especially important if you’re going to be cutting a lot of firewood or working with large trees. 

This means that it will have more power and be able to cut through thicker logs faster than its counterpart. The chain pitch on the STIHL MS 231 is 0.325″ while on the STIHL MS 251 C-BE, it’s 0.325″. The difference in chain pitch isn’t very significant because they are both low-quality chainsaws, so they will both dull out quickly when used consistently over time.

STIHL MS 231 vs MS 251 C-BE|STIHL Oilomatic saw chain type

The MS 231 is a small chainsaw designed for light-duty work around the house. It has a 21.7 cc two-stroke engine and weighs 7.2 pounds. The MS 251 C-BE is also a two-stroke machine but its larger 27 cc engine allows it to cut faster, more aggressively, and with less strain on the user. It weighs 8 pounds and measures 18 inches from handle to blade tip.

The MS 231 uses an automatic oiler system that releases oil onto the chain as you cut, which keeps it well lubricated so that it doesn’t overheat or wear down abruptly. The MS 251’s manual oiling system requires you to keep an eye on your chain’s level of lubrication and add oil when necessary. Both machines have durable steel bars and chains that should last for years if properly maintained with regular sharpening and oiling.
