I brought my car into the dealership today. The mechanic/service adviser took a look at it and said everything seemed fine and took it for a drive around the block and when he came back he said he did not see the oil light come on once. He said he even hit VTEC and everything seemed and felt perfectly fine. The mechanic/service adviser told me that it was probably something that built up in the VTEC solenoid that was setting off the sensor and told me there would be no mechanical work/replacement parts needed (coming from a stealership, I trusted his words). Sure enough, when I got my keys and drove home the light did not come on once.
I will however be looking at getting an oil pressure gauge in the near future (I still don't understand why our cars don't have one from the factory or at least an option from the dealer).
The screen on the vtec solenoid is easily cleaned, might be worth looking at. I inspected mine when I first got the car just as routine maintenance, but it was very clean.
What kind of oil are you using, oil thins when heated. Why is it that vehicle problems never show up when you take the car into a dealership to inspect ?, lol.
If it were my car, I'd want to make CERTAIN that I had correct oil pressure. It's the life-blood of the engine. It does not sound as if the mechanic at the sealer checked this, so do it yourself with an inexpensive mechanical oil pressure gauge.

yeah it doesn't sound like the dealer put much effort into finding the problem. I truly hope a mechanic looked at the car and not just the service advisor. Believe me, service advisors know less about your S2000 than my wife, do not take their word on anything that has to do with the mechanicals of your car.
I think I would have asked them to perform an oil pressure test on the car and just pay the cost for peace of mind.
When I was about to buy an oil pressure gauge I took a quick look under my hood to check how I would go about wiring it up. While I was looking, I noticed the wire connecting to my oil pressure switch was a bit burnt up and the wiring was exposed. I got a friend to sit in the car with the car on while I wiggled the wire. This wire sits very close to the timing chain tensioner and when it made contact with the timing chain tensioner, it set off the oil pressure light. When the wire did not make contact, the oil light would remain off. This would explain why only sometimes my oil pressure light would come on. Especially during braking/cornering since the force would be enough to move the wire and make it contact the tensioner. It makes sense at speed because I imagine wind enters through the grill and moves the wire around too.
To fix this problem, I decided to wrap the exposed wiring in electrical tape. Sure enough, after 5000~ km's I have not seen the light come on once.
I've included pictures below in hopes of this making more sense. (The wire with the red outline is the part that was burnt) The picture on the right is what it looks like after my "repair".
