Hey all...

I have been filling up with Sunoco Ultra 94 gas (the one with 10% ethanol), as this is the highest octane gas around me, but I recently filled up with Shell V-Power gas (91 octane) and the car feels faster and smoother?????

Can it be that the boxster does not like ethanol additives in its gas?
