What 2 stroke mix for a stihl

[scbk]

Just wondering, owners book says Stihl oil at 50:1, or "other branded 2 stroke engine oils (classification TC) 25:1"

 

So what mix rate should Oregon semi synthetic 2T be at?

[jrose]

don't know about the oregon oil specifically, but I tend to mix it at 50:1 no matter what the brand of 2 stroke. That being said, I do only use Stihl or Husky oil, occassionally Makita oil but not often. I try and steer clear of the Tescos own 2 stroke but that's just me!

We use both Stihl 2-mix and 4-mix. Both of em are 50:1 so 100 ml to 5 litres of fuel. Better to use the branded stuff than other peoples own. Oregon Semi synth 2T should be 50:1. Typed into the wonderful search engine that is Google and it came up with the fuel mix.

Stihl say 25:1 on anyone elses oil other than their own, this is due to not knowing the quality of other peoples oil. They may try to invalidate your warranty on this basis if pushed!

I use 50:1 in my 346/357 all the time using husqvarna two stroke oil. Just wondered, what effects would running a mix that is more rich with oil do for the saw?

Many years ago in the dark ages, two stroke oil was not what it is today and 25:1 was the norm, oil technology has come on since then and 40:1 - 50:1 is quite normal now and the ratio is dependant on the oil used rather than the engine using it.

 

I use a 40:1 mix as the extra cost is minimal and it protects the engine a bit more if the fuel/oil mix goes past it's optimal life and also if you spring an air leak, H setting lean etc.

 

Amsoil is mixed at 100:1 - they also sponsor the Lowerstoft FC powerboat - that is one decent bit of kit:thumbup:

I run 32:1 in everything. Plus side, easy to measure out of my quarts and gallons containers for bulk mixes at 4 ounces a gallon. Plus the 100 and 200 mixes with ethanol The R-50 does not stay mix with ethanol and they said not good on any above 10%, be warned about that. I talked to a tech at Klotz on the subject.

You need to start making sure your oils mix with ethanol blended gases and stay mixed, if you have it.

Super if you cut in really warm weather with 20% bean added.

does it make the saw run any better if mixed at 40:1?

[raker]

I run my saws on 40:1 with the Stihl stuff.No noticeable difference next to 50:1. It just gives a bit more lubrication. I`m not on a budget when it comes to looking after my gear.Any more and i think you`re going to get carbon build up all over your piston crown and in the exhaust port.
