With these cars slight overfill is less dangerous than underfill. I always make sure mine is never below fill mark, even if I only have to add 100ml. Regular oil changes will make that chain last a lot longer.
The tensionner has 3 stages of tightening once it reaches the last stage and chain has too much play, you should change the chain.
The tensionner in it's preset protrudes .3 inches, first stage will release it so the play is between .3" and .45", second stage is from .46" to .6" and last stage is from .61" to .84".
So as you can see the tensionner is designed to take up to .5" of play out of the chain as it stretches or rather as links wear.
Never drive faster than your guardian angel can fly
