and today I screwed up and put 5w-40. What do you guys recommend? Do you think it will hurt the vehicle this one time?
I change oil every 5k miles and I live in Fl. I keep reading mix reviews that the oil I used 5w-40 is fine just don’t make it a habit. Any insight would be great thanks guys.

Don’t worry.
In fact, I think you screwed up in the right direction, lol. I'm in Florida and I run 5-40 because between the two, zero weight is suited towards better flow in low temperatures and 5 weight is suited more towards higher temperatures, like Florida.
I say you did the right thing!

Also no need to worry about mixing these weights because they are so close in specs.
From what I read, the engine will be okay unless you have express cold.
Edit to fix the information

0-40 is more suitable for colder climates.
5-40 is more suitable for warmer climates.
But as said, it's not all that crucial unless you are running at great extremes with heavy duty cycles.
