okay, my little pug 102 has been running really sluggish lately, she's all stock and i am waiting on funds to mod her up with a 50cc kit, but i still ride her everyday to and from work so i put some 91 in her this morning and noticed some improved performance, will this damage my tank or engine anyone?
Shouldn't have made a difference except maybe the alcohol added some oxyenation. High octane gas is more likely to have the 10% alcohol that they warn you on the pump about. The alcohol in that concentration isn't really a problem and a oxygen molecule gets spun off alcohol easily during combustion. Some fuel injection cleaners can give you a similar sensation
