From Honda S2000 Wiki


Mobil1 5W-50 Engine oil names

Currently named "Mobil1 FS X2 5W-50" but previously also known as:

  • Peak Life
  • Rallye Formula
  • FS X1

Description

Oil analysis from other Honda S2000 drivers have shown that the oil is not too thick for the S2000 and that it's viscosity at @100ºC breaks down after very few kilometers of usage.
This essentially makes it a fitting oil with the advantages of a "thin" 5W-40 while retaining the capabilities of a "durable" 5W-50.
