Maintenance at 1521 Miles Plus Some Other Questions

[TurboWarp]

Hi All,

Still loving and learning my 2026 CT5 V BW. I was considering an oil change as a safety measure. I dont see a concensus on this. Thoughts about any maintenance for this new car?

Other Questions:

-On the headlights stalk at the end of it there is a round spring loaded button that pushes into the stalk. Dont see this in the manual. Anyone know what this does?
-If I put the exhaust note in stealth mode does it impact performance?
- At idle after full warm up, engine runs a little rough most of the time; is this normal?

Thanks....

I don't care what anybody says. I have ALWAYS done a break in oil change on my new cars at about 1000-1500 miles. I used my free 1st oil change to do it. Its cheap insurance. Every engine builder that I have ever known does it too.
My 2022 5BW/auto has only 6800 miles on her in just over 3 years of ownership and its had 4 oil changes.
