Personally, I use the cheap stuff for the basic reasons as stated above. Here's a thought, in the heat of summer if you're running your engine hard, it may be helpful to use higher octane gas if the engine is running hot...but that's only a maybe. I've never noticed any problems on hot days, but it might be worth a try.
Thanks Terminal. that was handy. It is noticeable that my Honda and the HuaSheng before it both reached their best ever performance in cold night air and I am assured that it is the dense oxygen rich night air that contributed to this very noticeable occurrence. It took me a while to realise that it was one particular journey I make infrequently when my engine just sang like a bird and was attaining crusing speeds way above its average of 50 km\hr.
I thought it was the long warm up at idl speed that the engine got during a 12 minute start riding at walking speed around pot holes before I hit the open road on this particular journey but that wasn't the contributing factor - it was the fact that I was running at night in winter with low humidity and dense air that really got the motor to sing.
