Engine oil change intervalls

The owners and service manual recommends the following intervalls:

Normal driving conditions: Every 12.000km / 7.500miles or 1 year (which ever comes first)
Harsh driving conditions: Every 6.000km / 3.750miles or 6 months (which ever comes first)

Most owners drive their S2000 only during the summer months and do a service (which includes an engine oil change) during the winter.
This means a service every 6 months and usually within 6.000km.

Recommended engine oil filter

It is highly recommended to only use the OEM filter with the part numer "15400-PCX-004".
There are several other options to choose from (even from Honda) but it seems like other filters can't keep up with the high oil flow speed that the F20C engine has.

Required tools and fluids

1x Honda oil filter #15400-PCX-0400
4,8L / 5,1 qts engine oil (or a little more if you would like to "flush" the engine)
New crush washer for the oil drain bolt
17mm socket
Ratchet
Torque wrench (24Nm / 18 lb-ft and 40Nm / 29 lb-ft)
Filter wrench or filter socket for yor ratchet
Oil catch pan
Floor jack + jack stands
Funnel (optional)

How to change the engine oil

Pre-conditions and jacking up the car

Make sure that the engine is not cold but also not too hot. 2-3 bars on the temp gauge are fine.
Put the car in the first gear and set the parking brake
Jack up the car on the front as well as the back and put the jack stands in place.

Draining the oil and removing the oil filter

The oil pan is located under the engine and the drain bolt is located on the front of the oil pan at passenger side.
Place your oil catch pan below the engine oil drain bolt.
Remove the engine oil filling cap on the top of the engine.
Remove the engine oil drain bolt with a 17mm socket from the oil pan.
The engine oil will now drain from the oil pan and you might need to re-adjust your oil catch pan.
While the engine oil is draining I recommend to also remove the oil filter. You will notice that once the filter is gone, more oil will come out of the engine oil drain.
Remove the oil filter completely. Be carefull as engine oil will leak out of the filter and engine.

Once all the oil has be drained I like to fill fresh oil into the engine to "flush" the engine with the new oil.
Wait until no oil (either old or new from "flushing") comes out of the engine.
