Stihl 362

Stihl 362

The Stihl MS 362 chainsaw offers several notable features that enhance its usability and performance. Firstly, it incorporates a decompression valve, which reduces compression in the combustion chamber during startup. The chainsaw also boasts a side-mounted chain tensioner system, allowing for on-the-fly adjustments to the chain without the need to stop the saw.

Additionally, the Stihl MS 362 is equipped with an exceptional anti-vibration system, ensuring maximum user comfort even at higher RPMs. Furthermore, the chainsaw utilizes a pre-separation air filtration system, reducing the frequency and intensity of maintenance tasks.

Pros and Cons of Stihl 362


  • Powerful 4.6 bhp engine, offering excellent cutting performance.
  • Effortless starting with the decompression valve, making it easier to pull the rope for ignition.
  • Anti-vibration system ensures comfortable operation, even at higher RPMs.
  • Lightweight construction, allowing for easier maneuverability and reduced user fatigue.
  • Suitable for professional use, meeting the demands of experienced operators.


  • Maintenance can be complicated, requiring additional time and effort.
  • Higher price point compared to some other chainsaw models.

Stihl 391 Vs 362


The MS 391, weighing approximately 13.67 lbs, is on the heavier side, requiring more effort to handle. In contrast, the MS 362 is slightly lighter, weighing around 12.3 lbs, resulting in a 1.5-pound difference between the two models. While this may seem insignificant, it can make a noticeable impact when working for extended periods.

The heavier MS 391 can lead to faster hand fatigue, making the task more challenging. On the other hand, the lighter MS 362 is advantageous for those who frequently move the chainsaw during their tree-felling routine, as its lightweight construction allows for easier maneuverability.

Specs and Comparison Table

Stihl 391 Vs 362

Engine Power and Displacement Variation

Engine power, measured in brake horsepower (bhp), determines the work potential of the motor without accounting for external factors that may affect its actual speed. The Stihl MS 391 is equipped with a 4.4 bhp engine, while the MS 362 boasts a more powerful 4.6 bhp engine. This indicates that the MS 362 has a greater engine power and overall capability compared to the MS 391.

On the other hand, displacement plays a role in determining chainsaw power. It measures the volume displaced by the piston during its upward stroke and is typically measured in cubic centimeters (CC) or cubic inches. The Stihl MS 391 has a larger displacement of 64.1 CC, whereas the MS 362 has a slightly smaller displacement of 59.00 CC. In terms of displacement alone, the MS 391 appears to have an advantage. However, this small difference in displacement does not diminish the overall power of the MS 362.

IntelliCarb™ Carburetor

The IntelliCarb™ Compensating carburetor is a technology designed to prevent the negative effects of a clogged air filter on chainsaw performance, such as overheating or poor operation. When an air filter becomes dirty and limits the airflow to the carburetor, this system adjusts the fuel flow to maintain performance.

The Stihl MS 391 chainsaw has this feature built-in, ensuring that it operates efficiently even with a dirty air filter. However, the MS 362 model does not have the IntelliCarb system, leaving it vulnerable to reduced performance and overheating due to air filter issues. Therefore, if you are looking for a chainsaw that can operate smoothly regardless of air filter conditions, the MS 391 might be a better choice.

Decompression Valve

The MS 362 is equipped with a decompression valve, commonly referred to as the ‘deco,’ which serves to lower the pressure in the combustion chamber during startup. This feature allows for an easier starting experience, requiring only a light tug of the rope to turn the saw on.

In contrast, the MS 391 lacks this valve, which means starting the chainsaw may require more effort and force. Therefore, if ease of starting is a priority, the MS 362 with its decompression valve may be a more favorable option.


Gas chainsaws, in general, require more maintenance than electric chainsaws. However, the maintenance of the Stihl MS 362 chainsaw is known to be more complicated when compared to the MS 391 model. The Stihl MS 362 chainsaw requires periodic chain position adjustments, which could add to the complexity of its maintenance needs.

Reviews from customers have revealed that improper maintenance could lead to unusual behavior from the MS 362 model, underlining its need for more frequent maintenance. In contrast, the MS 391 model may require less maintenance attention, making it an easier option for those who want a chainsaw with lower upkeep requirements.


For those with a limited budget or smaller projects, the Stihl MS 391 can be a suitable option as it offers essential features while providing value for money. The price range for the Stihl MS 391 with an 18-inch bar chain typically falls between $630 to $670+.

In contrast, acquiring the Stihl MS 362 with the same bar length would require an additional investment of approximately $200. The Stihl MS 362 is priced around $870, making it significantly more expensive than the MS 391. Therefore, if cost is a significant factor in your purchasing decision, the Stihl MS 391 may be the more affordable choice. You can check the latest price from here.

Which One Should You Choose?

When it comes to choosing between the Stihl MS 391 and MS 362 gas chainsaws, several factors need consideration. The MS 362 offers the advantage of a decompression valve, making it easier to start. However, it requires more complicated maintenance and comes with a higher price tag. On the other hand, the MS 391 lacks the decompression valve but is more budget-friendly and requires less frequent maintenance.

If you prioritize ease of starting and are willing to invest more in maintenance and cost, the MS 362 could be the right choice. However, if you have a limited budget and seek a reliable option with lower maintenance needs, the MS 391 may be the more suitable option for you. Ultimately, the choice depends on individual preferences, project requirements, and available budget.
