Stihl MS 250 Review: The Power-to-Weight Benchmark for Homeowners
For over a decade, the Stihl MS 250 has occupied a legendary sweet spot in the chainsaw market. Positioned between occasional-use homeowner models and 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? We ran this saw through 30+ acres of mixed hardwood to find out.
At a Glance: The Mid-Range Heavyweights
| Product | Displacement | Weight (Powerhead) | Power | Best For |
|---|---|---|---|---|
| Stihl MS 250 | 45.4 cc | 10.1 lbs | 3.0 bhp | Firewood and felling |
| Husqvarna 445 | 45.7 cc | 10.8 lbs | 2.8 bhp | Clean-cut efficiency |
| Echo CS-400 | 40.2 cc | 10.1 lbs | 2.2 bhp | Lightweight handling |
Stihl MS 250 Review: A Punchy 45cc Engine
The heart of the Stihl MS 250 is its 45.4 cc (2.77 cu. in.) engine, delivering a robust 3.0 bhp (2.2 kW). What sets this saw apart is its exceptional power-to-weight ratio. At just 10.1 lbs, it offers the torque necessary to pull through 18-inch logs without the fatigue of heavier 50cc+ professional saws.
Torque and Cutting Speed
During our field testing, the MS 250 excels in bucking downed trees into logs. While it is rated for bars up to 18 inches, we 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.
Honest Downside
Like all high-performance 2-stroke engines, it requires high-quality ethanol-free fuel to prevent carburetor issues. The starting technique requires a specific feel for the choke that may take beginners a few tries. The automatic chain oiler is fixed and non-adjustable.
Who It Is Best For
Property owners who need more than a toy but do not want to spend $600+ on a professional-grade saw. If you are looking for a one-saw quiver that handles storm cleanup, firewood processing, and general property maintenance, the MS 250 is arguably the most cost-effective gas saw on the market.
Chainsaw Safety
The MS 250 generates enough power to be dangerous in inexperienced hands. Always wear full PPE: hard hat with mesh face screen, ear muffs, cut-resistant chaps, and boots with ankle protection.
A chainsaw is only as safe as its operator. Study our chainsaw safety guide before tackling serious cutting.
Maintenance
The MS 250 incorporates a tuned anti-vibration buffer system that isolates engine vibrations from the handles. The side-access chain tensioner makes quick adjustments easy without removing your gloves. The pre-separation air filtration system with winter/summer shutter allows the carburetor to operate at optimum temperatures year-round.

Gas vs Battery
Battery-powered saws in the 40cc equivalent class are closing the gap, but they still cannot match the MS 250 runtime for all-day firewood processing. If you need to work for hours without stopping, gas remains the answer. Check our gas vs electric chainsaw guide.
Final Verdict
The Stihl MS 250 remains the Gold Standard for property owners who need more than a toy but do not want to spend $600+ on a professional-grade saw. It strikes a perfect balance: light enough for limbing branches, yet powerful enough to drop a 15-inch maple tree.

Frequently Asked Questions
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 ethanol-free fuel.
What is the difference between the Stihl MS 250 and the MS 251?
The MS 251 is the successor with a more fuel-efficient stratified scavenging engine that reduces emissions. However, the MS 250 is slightly lighter and many users find it easier to service due to its simpler engine design.
Can I put a 20-inch bar on an MS 250?
While physically possible, we do not recommend it. A 20-inch bar puts significant strain on the 45cc engine and slows down chain speed, leading to bogging and premature engine wear. Stick to 16 or 18 inches.
Why does my MS 250 flood so easily?
Starting a Stihl requires a specific sequence: full choke until the first pop, then immediately move to half-choke for the second pull. Leaving it on full choke after the engine fires will flood the cylinder.
Does the MS 250 have an adjustable oiler?
No. The automatic chain oiler on the MS 250 is fixed and non-adjustable. This may be a downside for those running longer bars in very dry wood.
Is the MS 250 good for limbing?
Yes. At 10.1 lbs, the MS 250 is one of the lightest saws in its power class, making it excellent for limbing and overhead work.
How long does the MS 250 typically last?
With basic maintenance, the MS 250 is known to last 15+ years. It is one of the most durable homeowner-class saws Stihl has ever produced.
Does the MS 250 have a winter/summer shutter?
Yes. The MS 250 features a pre-separation air filtration system with a winter/summer shutter that prevents carburetor icing in winter and overheating in summer.
