Hello Everyone
Had bought a decent k24A3 and swapped into my civic ek 3 months ago. It has almost ran 3,000Km since then.
The first Oil change I did was Idemitsu 10w40.
Now I would need safe recommendations regarding either I should go with which oil keeping in mind that winters are coming in Islamabad and Engine is 20 years old
1- 10w40
2- 5w30
3- 20w50 (Engine is old, like idk)
Currently the setup is N/A with everything stock except headers.
