Stihl MS250 Vs MS251 – Which One is Better in 2023?

Stihl is among the leading chainsaw manufacturing brands – it has streamlined quite an impressive variety of chainsaws to facilitate users according to their requirements. Earlier, Stihl put in line the production of Stihl MS250 which earned huge satisfaction from customers across the USA. Meanwhile, to further improve the quality of their product, Stihl took a step forward and launched Stihl MS251 as a successor of Stihl MS250 – of course, the former is better than the latter in terms of emissions, fuel capacity, etc.

Users are skeptical if Stihl has truly added something new to Stihl MS251 or if it is the same chainsaw with a new name. I would say, although Stihl MS251 has a lot of similar qualities to Stihl MS250, it will not be appropriate to say that the former is similar to the latter; there are many technical as well as physical differences in both of these power tools.

What are main Differences?

Having discussed the features of both of the chainsaws, now I am due to tell you about the main differences that exist between these two chainsaws. Followings are considerable differences that make these machines differ from each other;

1. Engine and Power

Physically, there is nothing different about the engine of these two chainsaws; however, technically there exists a very minor difference in cylindrical displacement. In MS250 cylindrical displacement is 45.4cc while in MS251 it is 45.6cc – although the difference is minor but still important to consider. 

Both chainsaws have engines that produce 3.0bhp. On a larger frame, there is no big difference in power offered by these two chainsaws, but Stihl MS251 appears to be a bit more suitable and powerful. 

2. Weight and Handling Comparison

Weight is an important factor that cannot be overlooked while buying a new chainsaw. Discussing Stihl MS250 and Stihl MS251, you will come to know that there is a very minor difference of 0.9 pounds in the weight of these two chainsaws. 

No doubt, this difference in weight is minor but still considerable. You can hold a lighter chainsaw with more convenience, while a heavier chainsaw can be more efficient while dealing with hard wood. 

3. Reduced Emissions 

Emissions are the leading cause of environmental deterioration. These are also harmful to users and people who inhale that air. Although manufacturers are very much careful about the manufacturing of their products, and developing technologies to reduce the harmful impact on the environment and human beings, but still there is a lot more to cover. 

The good thing is that Stihl MS251 is equipped with an excellent emission reduction system that reduces emissions by around 50% in comparison to Stihl MS250.

4. Chain Oil Capacity 

Lubrication of parts of chainsaws (especially of chain and bar) is very important to enjoy improved performance and continued efficiency. For this purpose, there is a tank of a certain capacity that contains lubrication oil for different parts of the chainsaw. In MS250 the capacity of the chain oil container is 6.80z. 

While this capacity is 6.7oz which is 0.1oz lesser than the capacity of MS250. This is a minor difference that can be overlooked anyway. 

5. Which has better Fuel Efficiency

Fuel consumption is an important factor that must be considered when buying a new chainsaw. Chainsaws that consume lesser amounts are surely more economical. Stihl MS250 consumes a regular amount of fuel which is consumed by other chainsaws of this size. 

But Stihl MS251 is better in this regard because it consumes 20% lesser fuel than MS250. This huge difference massively hails MS251 as a better chainsaw than MS250. 

6. Updated Prices
