What you using for engine oil?
I hope good quality oil.
I use Mobil 1 5w30 ESP.
A lot of oils out there are ****, like Castrol oils are garbage.
Anyways for what it's worth try the Mobil 1 5w30 ESP, in my opinion is is one of the top oils to use.
You do not need a 5w40 oil.
Your car like my 2015 tdi call for a 5w30 oil.
Like gassers calling for 0w20 and 5w20, as you listen to them you can here the valve train ticking away.
The gassers need a 5w30 in them as I installed in the wife's 2019 Honda Civic coupe.
