The warranty on my 12 month old 3120 is void if I use anything other than 25:1 and have a failure. I'm sure it'll run 50:1 but I won't take any chances and have been running 30:1 and will continue to do so. Mineral 2 stroke tends to foul the plug at 30:1 so as in everything I now run full synthetic.
MCW, they must not have any emission control in Ausie to make you run 25:1.
At this ratio, there may be a better chance of burning up the saw due to carbon build up, unless the saw was adjusted to max rpm specs and used WOT.
It would be pretty easy to get around the stupid warranty if it died at 50:1. You'd just have to pour some straight mix in the SP hole and some more in the tank! lol
