Q: I had about 1/4 tank of regular gas, and accidentally put super premium gas to fill up the rest, should I be worries? Will it mess

I filled up my tank with super premium gas and it still had 1/4 left of regular gas

My car has 67000 miles.
My car has an automatic transmission.

This should not cause any issues at all with your vehicle. The premium fuel is simply a higher octane fuel which will has additional additives in it that help to prevent what is called pre-detonation, also known as pinging or knocking. Your vehicle should be just fine with this fuel in it.
