Premix vs Two Stroke Mix - Comparison Inside the Saw

Would you summise that the 2 stroke oil that Aspen use in the premix is at fault or rather that the burning character of aspen (hotter?) removes the oil film? Would it therefore be better to use Aspen 4 but add your own superior quality 2 stroke oil?

I use Aspen 4 or the Husqvarna version and mix it with Red Line 2t racing oil . Never a problem .

At about £100 for a gallon, that stuff is not cheap, 3 or 4 times as much as Stihl/Husqvarna two stroke oil!

I like to use Aspen in dense woodland where there isn't much open air as such. Too expensive the rest of the time. I use Stihl HP Super (green) or Castrol 2T racing I think it is. I've read that other page about HP Ultra which is lower spec than Super and is just emission BS.

If the engine hasn't seized then I would say that the fuel/oil have burnt off or evaporated leaving the engine looking clean rather than carbonizing leaving carbon and oil. So...no issue or problem, it's done what you buy it for.

There was no issue with either of these saws. I put the photos up to show the comparison with both types of fuel / mixes.

i would say it probably removes the oil film. If I was to use it I’d say use 4 with your own oil but that’s just my opinion. I use super unleaded and HP super. Don’t have any issues. I don’t see the need for alkylate fuel but again that’s my opinion.

Was that  my 572 on the Motul Mark ? I read these posts about mix v Aspen etc with interest. As noted the Aspen or the Husqvarna blend is without doubt a clean fuel. When Aspen was first around I was given a ltr and I tried it in a strimmer and my feelings - it was to "clean" which is shown in the picture from Mark of the 572 bottom end. Some time ago on this forum I asked the member AspenUK, after he declared that the oil in Aspen was the finest around that exceeded every other oil , what oil standards it exceeded and I was given some rubbish about commercial sensitivity ... I wasn't asking for the details of the mix just a idea of why it was so far ahead of other oils ? on looking it seemed to be no more advanced than any other high quality oil. I've been using Motul 800 for several years and get around 5 years out of a highly modified saw which I don't think is bad on a work saw doing 5 days a week.

no, it was another customers. I like to know what oil goes in the saws too. That and the price of premix puts me off using it. I also hate the smell 😂
 

i think the way you run your saws is proof that good oil goes a long way!

i must say that i run my 560 on the husky power2 premix and it loves it but there again im not using it for long periods so the shelf life of the fuel gives me the added benefit of leaving the fuel in between uses .
