What's the best fuel for chainsaws?

Back to the Aspen....one common issue is the hardening of fuel lines. This shows up especially well on MS200Ts where there is an interference push fit on the fuel line with the fuel tank to make the seal. When the fuel line shrinks, you get a weep and then a leak of fuel around the fuel line. Seen this many times on Aspen changes and also on MS200ts left with no fuel in their tanks for many months.

I had one customer move to Aspen and complained most of his kit had stopped working. We had a few of the above issues but mostly a quick carb strip, clean and readjust got most of his kit working. 

I guess a lot of it is people in the know just do the tweaks that work once the change is done and those that don't know, make a drama out of it. Much depends on your relationship with your repair service guy.

 

 

 

So is it better to stick with the stihl fuel?..

I have recently bought the ms201tc and it was used with e5 and mixed with the stihl oil so I am wondering if this is going to affect the saw if I start using the stihl fuel..

If you mean Stihl  Motomix then that is an alkylate fuel similar to Aspen and Husqvarna Xpower . So all or some or non of the above may or may not apply 🙂

The Stihl Motomix, Aspen and the Husqvarna fuel will all potentially cause the same issues with the rubber parts in your saws hardening up due to petrol having degraded the parts and then lack of petrol in using an alkalyte fuel, making them go hard. Using all Stihl products won't stop the potential issues happening.

 Some don't see any issues but having had a lot of saws across my bench over the years, some guys don't notice much and won't see a fuel line hardening up or the fuel line seal beginning to leak etc.

You have to factor in cost of specialist fuel, how much you prefer the smell of Alkalyte against petrol, the possibility you may need new carb parts and fuel line in time etc
