Classic Gear ZC 90 is a mild SAE 90 transmission oil with extreme pressure protection that is suitable for classic transmissions. Modern transmission 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
Recommended Transmission Oil Change Intervals
Fiat originally recommended the following transmission oil change intervals:
Fiat 500 models: Every 20,000 km
Fiat 126 models: Every 30,000 km
We recommend following these intervals, with a maximum of 5 years between oil changes, whichever comes first.
