I agree on just checking the oil and topping it up.

Luckily there’s more options too if it’s too late and there oil leaking beyond just burning a little the gaskets need to be dealt with.

A nice hack is also to meet a Honda mechanic who can take care of it privately.

Oil burning was a common problem for early S2000s (specifically AP1 motors) and AFAIK (having been an owner for 10+ years and read nearly every s2ki/s2kca forum post over the last 20 years), the problem was never truly solved in a documented, reproducible way.

Replacing the valve stems, seals, changing oil brands/weights, etc. have all been a bit unscientific and for me, the only thing that’s “worked” was not overfilling (as anxious owners tend to do), checking early and often, and ensuring I read the dipstick correctly (the trick on this motor is to read both sides of the dipstick).

Unfortunately, Honda always held firm on the "1 litre per 1000 miles is considered normal” and the problem went away with the F22C/AP2 motor. I've learned to live with it for an otherwise extremely reliable ownership experience.
