Classic Gear ZC 90 is a mild SAE 90 transmission oil with extreme pressure protection that is suitable for classic transmissions. Modern transmissions oils are frequently low-viscosity oils and are significantly less suitable, or unsuitable, for use in the transmissions of classic vehicles. That is why Kroon-Oil has developed Classic Oils. A complete range that is tailor-made for use in classic vehicles. Premium mineral base oils and carefully selected additives provide Classic Gear ZC 90 with the following properties:

  • Outstanding lubrication properties
  • Good resistance to corrosion
  • Mild EP properties
  • Compatible with bright metals such as copper, bronze and brass
  • Compatible with classic seals and rubbers
  • Good resistance to foaming


Classic Gear ZC 90 is a mineral SAE 90 transmission oil. Suitable for light to medium load manual transmissions and other transmissions in classic vehicles that require a mild, single-grade oil with extreme pressure protection that meets the API GL-3 specification. Classic Gear ZC 90 is also suitable for manual transmissions in classic Alfa Romeos, Fiats and Lancias that require an OlioFiat ZC 90 transmission oil.
