I use it in my 50cc motor scooter since it's got a barely 1 gallon tank that lasts me ~2 weeks a fill, so the price difference is negligible
I figured the higher octane would make a noticeable difference since it's such a small engine
But reading this thread I'm now thinking maybe I shouldn't do this?
As an update I have since started using standard gas as the manual recommends and think the performance might actually be better now
