Although both are successive models, they are different model actually and differs in many features.

So, this section would be about the features that distinguish each other separately and makes one stand out. And this way, it will be easier to pick the winner from each feature set.

Stihl MS179 VS Stihl MS171_ Which Is Better

Engine power

The efficiency of a cutting saw is primarily determined by the power of an engine. The higher the power, the more the saw can rotate or move. And when this becomes possible, more saws can be placed into the chainsaw, which will increase its capacity even to cut a whole tree from the root.

The engine power of ms171 is 1.71 bhp which is equal to 170. That means Stihl hasn’t made any changes here.

Winner: Tie

Pre-separation air filter

The pre-separation air filter takes the bigger dirt particles out of the way from being filtered in the filtration chamber. This keeps the air filter clean and saves from being dirty frequently. This saves you from manually cleaning the air filter over and over.

That being said, it’s a pretty important feature nowadays. 

We see Stihl ms170 lacks these features while added on ms171.

Winner: Stihl ms171


The weight of a chainsaw is a great deal since it’s directly correlated to the operator’s comfort.

The weigher the chainsaw would be, the more difficult it would be for the operators to operate it.

Both chainsaws differ in weight, although both are lightweight and made for homeowners in mind who can do small cutting jobs.

The power head weight of ms170 is 8.5 kg, and ms171 is 9.5kg. So, the importance of ms171 is at least one kg higher than ms 170. This means stihl ms170 is more lightweight and would be comparatively easier to operate.

Fuel tanker capacity

Both models differ in their fuel tanker capacity. Generally, the more fuel an engine can carry, the better it’s considered.

Stihl ms170 can carry 8.5 oz of oil, while 171 can carry 9.1 oz. So, Stihl ms is superior in terms of fuel capacity.

Winner: Stihl ms171

I’ve used the data and facts to pick the winner, and you see ms171 wins in most features. That made it apparent that Stihl ms171 is better.

Chain oil tanker capacity

Chain oil is important to lubricate the chainsaw. The more the oil tanker carries, the longer it can lubricate the chainsaw and keep the saw functioning properly.

Sthil ms 170 comes with a giant oil tanker with a weight of over 8.5 oz. At the same time, the ms171 weight is only 6.1 oz.

Probably Stihl was trying to cut the weight as it is already higher than ms170, so they might have done this to keep the weight in check.

Winner: Stihl ms170
