Aussie2, our octane ratings are different to the USA, we both use numbers that sound the same, but it is a different rating system. AFAIK there is ethonal in all our unleadeds, both normal and premium. The one I am fairly sure doesnt have ethonal is BP Ultimate 98 octane. I have been told by Kart racing guys that the Shell Optimax 98 (or what ever it is) does have ethonal. They had problems with it at a race meet and when engines were stripped done they could trace the problem back to moisture in the carb.
Now I recokon ethonal would be worse than running at 40-50-1.....Nothing wrong with changing the fuel oil ratio for what ever a person wants, that is their choice. But it must be retuned to that new mix.
Are all your dealers telling you to retune with the new mix or is that just taken for granted?
what blown huskies does he have haha :hmm3grin2orange:
BTW I run BP Ultimate 98 and a blend of maxima 927 with Husky xp oil (50/50) @ 40-1 in all my saws, blower and string trimmer. By the sounds of it, I would not do any where near the work on my stuff as you, nor in your heat...
