Petrov defense is good for 1600+?

I like the positions generated by the petrov defense.
But they say it is a very defensive.
Do you think it is bad to play the petrov defense for a 1600+ player? Is it bad to improve?
I love to play the endgame

If you want an endgame, the Petroff is not the answer.  The Petroff is mistaken as a dull opening.  It is not except in one line that White may choose to play, but that is White's decision and is rarely played.  The Petroff is actually a very aggressive defense, but the symmetrical pawn structure turns some people off.

If you want an endgame early on, the Berlin Defense is your answer.  White has a couple of sidelines to avoid the endgame (4.d3 or 5.Re1), but they are not scary.

There is nothing wrong with a 1600 playing the Petroff, but if your reasoning is to reach a quick endgame, you do not understand the Petroff and are playing it for all the wrong reasons.

I liked your answer. Thank you
I like the positions that the symmetrical structure of the pawn and with space. And the petrov defense allows me to get this structure.
You are right, I have lost many games for not knowing what tricks White has on the petrov.

My fear was, that I had a boring opening and that I was wasting my time studying it.

you can see the stats of that defense:

with 47% of draws, is the best for play for a draw

At 2200+ levels there is no difference between 2.Cf6 or Cc6

at blitz games there are few draws  

(why are you using lichess?  )

Petroff is good enough for Caruana and also just about every Chinese GM.
