You'll be fine. Next oil change just make sure you grabbed all the same stuff.

It will be slightly thinner, but not something to worry about. If more than 50% of the oil in there was the w20 kind then yes I would worry, but not when only 20% is like that.

By the way, these cars take 5.5 quarts. You should add another half quart.

I run 10w40 with no issues so far.

It won't hurt anything... If it bothers you, just run that oil for 500 or so, seafoam the crankcase, and change again.
