I have a 2023 Civic Si.

I did every oil change at around 8k miles which is when my maintenance minder popped up, even though the dealer recommended every 5k. No issues ever, now at 46k miles.

Pros: no issues ever
Vehicle: Honda Civic
Mileage: 8000 km

Mobil 1 FS is the absolute best you can give your car, in my humble opinion, but any modern fully synthetic will be more than enough.

Pros: absolute best, fully synthetic

OEM Honda Engine oil

I ran 10W-50 and 10W-60 for a few years in an old and beaten up Honda in the hope of reduce oil consumption to avoid having to open the engine. Long story short: it's not harmful, it's an expensive gimmick, the only real-life effect is fuel consumption will slightly worsen and that Honda had occasional issues with VTEC (a well known issue in those engines when running high viscosity oils).

Pros: not harmful
Cons: expensive gimmick, worsen fuel consumption
Vehicle: Honda

Cons: engine burned oil
