While watching a beautiful girl walk past at the gas station I accidently picked up the wrong pump and filled up with 93 premium fuel. What problems can this cause because I'm pretty sure these cars were made to run off regular unleaded. [:@]
You'll be ok, just wasted a little money that's all.
If your car was tuned for 93 octane and the same girl walks by and you pump regular gas by mistake, then you would have some detonation.
