Stihl Motomix

mad dad

Hi,

This is Stihl premixed fuel for two stroke engines. I spoke to a Stihl mechanic and he reckons Aspen 2 makes some Stihl engines run too hot and reckons Motomix is the best due to the use of Stihl Ultra HP oil (He has no vested interest). I'm looking for it for a new Mtronic Stihl chainsaw.

So I'm trying to get my hands on some of this but it's next to impossible.
Can anyone help or have suggestions on how I can go about getting it. Stihl themselves aren't selling it in the republic at present. It's available but appears very hit and miss in dealers up North but they won't ship. It's freely available in UK Stihl dealerships.

Any ideas/thoughts?

I got Motomix from Pat Fogarty near Portlaoise a few months ago:

However, it was out of stock recently so I went with Aspen 2 instead.

He appears to carry both of these brands of alkylate fuel (along with BestFuel) on an adhoc basis depending on availability.

I've used all three interchangeably across a range of 2 and 4 stroke small engines (Stihl, Husqvarna, Tanaka, Briggs & Stratton, etc) without any issue or concern.

You could always get a 4 stroke alkylate from one of the other brands and add the Stihl Ultra HP yourself if you really want to stick with the Stihl oil.

Are these fancy fuels worth it?

I use ordinary petrol with a good quality two-stroke oil (Mobil semi synthetic) and never have any problems, even when fuel is left in machine for long periods (I know I shouldn't!)

Agree, get a good two stroke. I use elf fully synthetic motorbike 2 stroke its better rated than the stihl 2 stroke too. No problems on my end and thats uswd with 5 different engines here. The important part if the correct mix.
That mix in the link is 23 euro for 5 litres! Mad money.

I ve only recently started using Aspen 2 , I agree it is very expensive but I ve noticed that after a few hours using it that I don't stink of 2 stroke and I don't get the headache that used to have from the fumes when using conventional petrol /oil.
If anyone knows where the Stihl version is available I d like to try it

I see your point of view but saws are becoming more and more advanced - electronic engine management systems (mtronic) etc and more pricey to match. I want to be sure I''m putting the best in as per manufacturers guidelines.
I'm an occasional user and my new saw could easily sit unused for 6-9 months and I want to be sure it'll start and perform when called on. There's well documented problems with leaving modern petrols in two stroke engines, gumming up carbs etc. Also as mentioned you have to get the mix right.... thats all taken out of the equation with premixed.
I accept motomix and aspen and such fuels are pricey but I'm willing to pay for the amount I'll use. I accept that what you guys do works for you and that's great but I want to take the doubt out of it. There's plenty of professional arborists/loggers who use these premixed fuels in their machines full time. They all can't be wrong - it's just another point of view.

Anyway .... Anyone know where I can buy Motomix??
