Stihl MS 250 Review: The Power-to-Weight Benchmark for Homeowners
For over a decade, the Stihl MS 250 has occupied a legendary âsweet spotâ in the chainsaw market. Positioned between the occasional-use homeowner models and the high-priced professional saws, the MS 250 is often cited by arborists and weekend warriors alike as one of the most reliable workhorses ever engineered.
But in an era of battery-powered advancements and newer models like the MS 251, does the MS 250 still hold its ground? In this data-driven review, we analyze the performance, ergonomics, and mechanical reliability of the Stihl MS 250 to help you decide if itâs the right tool for your property.
Quick Comparison: The Mid-Range Heavyweights
| Product | Engine Displacement | Weight (Powerhead) | Best For | Price/Check |
|---|---|---|---|---|
| Stihl MS 250 | 45.4 cc | 10.1 lbs | Firewood & Felling | Check Price |
| Husqvarna 445 | 45.7 cc | 10.8 lbs | Clean-cut Efficiency | Check Price |
| Echo CS-400 | 40.2 cc | 10.1 lbs | Lightweight Handling | Check Price |
Performance & Power: A Punchy 45cc Engine
The heart of the Stihl MS 250 is its 45.4 cc (2.77 cu. in.) engine, delivering a robust 2.2 kW (3.0 bhp) of power. What sets this saw apart from competitors is its exceptional power-to-weight ratio. At just 10.1 lbs (dry weight), it offers the torque necessary to pull through 18-inch logs without the fatigue associated with heavier 50cc+ professional saws.
Torque and Cutting Speed
In field testing, the MS 250 excels in âbuckingâ (cutting downed trees into logs). While it is rated for bars up to 18 inches, many professionals recommend a 16-inch bar for optimal chain speed. With the 16-inch configuration, the saw maintains high RPMs even when buried in hardwoods like Oak or Hickory.
Cold Start and Reliability
The MS 250 utilizes the classic Stihl Master Control Leverâą, a single-lever system that manages the choke, starting throttle, and on-off switch. While newer âEasy2Startâąâ systems exist on other models, the MS 250âs traditional recoil start is favored by purists for its simplicity and long-term durability.

Stihl designed the MS 250 for extended use. High-end technical features include:
1. Anti-Vibration System
Extended chainsaw use can lead to Hand-Arm Vibration Syndrome (HAVS). The MS 250 incorporates a tuned buffer system that isolates the engineâs vibrations from the handles. This allows for longer work sessions with significantly less hand fatigue.
2. Side-Access Chain Tensioner
Unlike older saws that required fumbling with the bar nuts to adjust tension, the MS 250 features a side-access tensioner. This makes it much easier to make quick adjustments in the field without removing your gloves.
3. Winter/Summer Shutter
A technical detail often overlooked is the Pre-separation Air Filtration System and the winter/summer shutter. This allows the carburetor to operate at optimum temperatures year-round, preventing icing in the winter and overheating in the summer.

Pros & Cons
The Advantages
- Legendary Durability: Known to last 15+ years with basic maintenance.
- Lightweight: One of the lightest saws in its power class.
- Easy Parts Availability: Because it is so popular, finding replacement filters, chains, and spark plugs is effortless.
- High RPM: Excellent for limbing and medium felling.
The Drawbacks
- Fuel Sensitivity: Like all high-performance 2-stroke engines, it requires high-quality, ethanol-free fuel to prevent carburetor issues.
- Starting Technique: Requires a specific âfeelâ for the choke that may take beginners a few tries to master.
- Non-Adjustable Oiler: The automatic chain oiler is fixed, which may be a downside for those running longer bars in very dry wood.
Final Verdict: Is the Stihl MS 250 Worth It?
The Stihl MS 250 remains the âGold Standardâ for property owners who need more than a toy but donât want to spend $600+ on a professional-grade saw. It strikes a perfect balance: it is light enough for limbing branches, yet powerful enough to drop a 15-inch maple tree.
If you are looking for a âone-saw quiverâ that can handle storm cleanup, firewood processing, and general property maintenance, the MS 250 is arguably the most cost-effective gas saw on the market today.
Frequently Asked Questions
1. What fuel mix should I use for the Stihl MS 250?
The MS 250 requires a 50:1 ratio of high-test (89 octane or higher) gasoline and 2-cycle air-cooled engine oil. For the best longevity, use Stihl MotoMix or an ethanol-free fuel.
2. What is the difference between the Stihl MS 250 and the MS 251?
The MS 251 is the successor to the MS 250. It features a more fuel-efficient âStratified Scavengingâ engine which reduces emissions. However, the MS 250 is slightly lighter and many users find it easier to service due to its simpler engine design.
3. Can I put a 20-inch bar on an MS 250?
While it is physically possible, it is not recommended. A 20-inch bar puts significant strain on the 45cc engine and slows down the chain speed, which can lead to âboggingâ and premature engine wear. Stick to 16 or 18 inches for the best performance.
4. Why does my MS 250 flood so easily?
Starting a Stihl requires a specific sequence: Full choke until the first âpopâ (ignition), then immediately move to half-choke for the second pull. Leaving it on full choke after the engine fires will flood the cylinder.
