You do some of this but you don't check if they need an oil change.

And you don't do this. You need a loop somewhere...

I suggest before worrying about the oil change code that
you get the input bit working, just print the two values
initially. Once you can correctly read two valid values
move on to using them to check the oil.

You don't store this value anywhere

This claims you need an oil change if the mileage at the
last change was >5000.

Even if I haven't driven any miles at all since then.
Something wrong. You need to use both the values that
you read from the user.

This doesn't make much sense. You compare x to 5000
but don't do anything with the result.
I'm not even sure what you are trying to do here.

Remember indentation is all important in Python.
Here you always print the message regar5dless of what
happened further up.

Probably that last indentation issue to blame for that.
More seriously you are not doing what the homework
assignment asks you to do. Read it again and see
my comments above.

Have another go and if still stuck come back to us.
