Your choice?

I own Stihl products and was told to use 93 octane in my machines. What gas would you consider using, 87 octane non-ethanol or 93 octane E10. Just thinking.

87 e free. Luckily i can get 91 e free

 

[stihly dan]

My stihl says 89

 

[KenJax Tree]

Guys here run 87 octane in ported saws

 

[sunfish]

I run 91 E-free, but would rather have 87 0r 89 E-free.

No, I would not run 93 E-10!

One winter about 10 years ago our winter was so snowy the falling/cutting came to a stop. I helped a friend in his saw shop that winter and into spring. After I saw the effects of ethanol on the guts of good saws, I will NEVER put E-anything in any two stroke!!!

I live in australia and i use 95 octane non ethanol

e-free, don't think the octane matters to much, but around here it's 91 octane for the ethanol free.

 

[snoozeys]

Around here they sell 91 95 e10 98 100 ... I think 98 is probably an overkill so 95 which they call premium unleaded seems like best for outdoor machine to me

Is that the RON?

RedMax and Dolmar spec 89 octane for my saws, so it's 89 e-10. What's available.

I will not run ethanol in anything other than a car/truck. I run 91 non-ethanol in all my small engine toys like chainsaws, dirt bikes, lawnmower, snow blower. It probably isn't needed in the lawnmower and snow blower but I find 91 stores a lot better/longer than anything with ethanol in it.

 

[Ironworker]

I use 91 with ethanol and never had a problem, I use additives and run my stuff dry before storing away.

 

[snoozeys]

Yeah it is

 

[snoozeys]

Is that the RON?

Yes it is

Sorry about double post

Non-ethanol 87.

There is nothing on that list within a hundred miles of me, as far as I can tell.

We need to be careful when discussing the octane of fuel with our members in different parts of the world. Not all countries use the same method of octane labeling as we do and it can become confusing for those who dont understand that.

Australia: "regular" unleaded fuel is 91 RON, "premium" unleaded with 95 RON is widely available, and 98 RON fuel is also reasonably common. Shell used to sell 100 RON petrol (5% ethanol content) from a small number of service stations, most of which are located in major cities (stopped in August 2008).[23] United Petroleum sells 100 RON unleaded fuel (10% ethanol content) at a small number of its service stations (originally only two, but it has now expanded to 67 outlets nationwide).[24][25] All fuel in Australia is unleaded except for some aviation fuels.

Here in the USA we use the PON which is the RON + MON / 2. Overseas I see a lot just going by the RON which most often will be higher but the same grade.
