Choosing The Best Motor Oil for Your Honda S2000

Get behind the wheel of an S2000, and you’ll enjoy its superior handling, seamless gear-shifting, and exceptional fuel economy.

However, to ensure that your S2000 is at its peak performance, you need to service it regularly. A key part of this involves using high-quality engine oil.

In this guide, we’ve compiled a list of the best motor oil options for your Honda S2000, be it for daily driving or harsh weather conditions.

The recommended engine oil weight for your Honda S2000 is 10W-30. This is the same whether or not your S2K is an AP1 running an F20C or or an AP2 with an F22C engine.

This oil weight should serve you well in normal driving conditions, especially if you live in temperatures ranging from -4℉ to 104℉.

However, if you’ve got an extensive list of aftermarket upgrades onboard or live in an area where extreme weather conditions are common, a high-performance oil engine oil would be better suited to your needs.

For example, if you live in an extremely cold climate, you can use 5W-30 or 0W-30. Similarly, 5W-40 or 10W-40 works well if your car is exposed to extremely hot conditions.

Another thing to look out for when purchasing engine oil is to ensure that it protects your engine against wear and tear. It’s usually the 0W-40 that provides great engine protection, as well as the 10W-40.

It’s important to remember that ultimately, your engine oil is only as good as your oil filter. Replacing your OEM oil filter in time comes in handy here, the part number for which is 15400-PCX-004.

If your Honda S2000 is tuned, expect to do more frequent oil changes, and use a different oil to the one that Honda recommends.

How Much Oil Does Your S2000 Need?

Before diving into the various oils available for your S2000, it helps to know exactly how much oil you really need. Some people don’t want to buy more than necessary, and others want to make sure that their engine has enough oil.

The Honda S2000 generally needs 5.07 quarts or 1.26 gallons of oil. That’s equivalent to 4.8 liters.

How Often Do You Need an Oil Change?

The Honda manual suggests that you change the oil every 7,500 miles. If you’ve exposed your car to severe conditions, you should change it every 3,750 miles.

If you’re wondering what “severe conditions” includes, this should sum it up:

  • Driving in extremely hot conditions
  • Prolonged idling or extended periods of stop-and-go
  • Driving on inhospitable terrains such as mud and mountainous landscapes
  • Taking a trip that’s less than five or ten miles in freezing conditions

3,750 miles isn’t very far. If you’re changing fluids yourself, it’s worth considering what many S2K owners do, and installing a quick drain oil plug. They can really make oil changes a breeze.
