Bit of an upper cylinder lubricant on the old Honda eh Kev?, it will run fine they do need a decoke though the 2 stroke oil leaves some nasty deposits around the valves and ports. The first sign is a loss of power.
TIP. go to your local light aircraft / heli field with a petrol drum and buy some Aviation Fuel [ av gas ] never have carby diaphram issues etc etc again.
also use a good full synthetic 2 stroke oil not the stock junk like Sthil / castrol etc etc. some of these oils can be mixed at a ratio of 100 to 1 , not like the oily 25 to 1 smoko.
by mem about 3000rpm is the optimum for cutting grass. faster isn't always better. it depends on blade width, you want blades to be going within a certain speed range.
Not at all mate, faster the better gets the better results and fills the catcher. Below 3000 most slip out of their sweet spot and lose all grunt.

Stihl oil is just Castrol or another mob that lay claim to the name. 25/1 is fine with cheap mineral based oil, but it results in much more performance, and less deposits if you run a leaner ratio such as 50/1 with a synthetic oil.
