You are bringing past experience with you and not all past experience apply to the S2000, as many, many S2000 "experts" have mistakenly done. In this case, no harm will come from checking the oil when hot or cold as long as it is checked.
Ordinarily, I could give a crap whether someone believes me or not. I just let them go on their merry way, basking in their own misadventures. However, in this case, because there are obvious newbies reading this, this will be the last time I will substantiate anything on this board.

In my owner's manual, page 119, in "Service Station Procedures" ....................
"Check engine oil level every time you fill the car with fuel. Wait a few minutes after turning the engine off before you check the oil."
Then it goes into a 4 step explanation as to how to do it. I won't type that here. I don't feel that altruistic today. Now, using common reasoning, do you suppose the oil will be hot or cold once you've driven to the gas station and "turning the engine off"? Unless you live 50 feet, right next door to the gas station or push it there, the oil will not be cold. It'll be luke warm at best and churned up. I already stated that a cold check is easier, quicker and more consistent (did I dispute that?), however, Honda has stated that that's not the way they want you to do it (for legal reasons and I won't go into what those might be). This obviously compensates for not all the oil coming back down into the crankcase, BUT, if done they way they say (waiting a few minutes), the difference will only be no more than 1 "X". The cooler the oil, the less accurate it will be.
I'm not saying anymore in this thread. This, like all oil threads have been beaten to death over the past 12 years. It has gotten WAY more attention than it truly deserves. Checking the oil in an S2000 isn't rocket science although some make it seem like it should be, just do it.

 

Yep if you're at the bottom of the stick it needs half a litre MAX and maybe less when it's warm - the most important thing to make sure of is that at least has SOME in it. Waiting for the idiot light to tell you it's low is playing russian roulette with your engine.

Pre 04 will drink up to a litre per 1000 miles and a post 04 will drink less, sometimes much less.

That said oil consumption is as much to do with operating conditions and the type and length of driving that you do.

It's far less expensive to get into the habit of checking it - the more you drive the car, the more you check the oil the more you'll be in tune with when it's going to require a top up.

Then you might as well just carry a 1L bottle around with you so that WHEN it needs some, you have some for it.

Pretty simple really!

 

I couldn't help but laugh at this.

 

....ah the good old days ...nice to hv u back

Questioning things is how I learn.. I dont just accept whatever someone says no matter who says it.

I am not saying I am right, I am just saying that it does not state that it is more accurate to check warm. It just says check after every fill up.

I assume like other cars the most accurate reading will be cold in any car including the S.. Once again I could be wrong but I dont see how the S is any different.

 

This. Neither way is "more accurate." Cold or hot may give you a slightly different reading, but either is ok as long as you are within the range. It's not like you need exactly 5.0000000 quarts.

 

This makes sense.
