Castrol Rustilo 66 VCI

Castrol Rustilo 66 VCI Neat Corrosion Preventive Oil


Castrol Rustilo 66 VCI is an oil-type protective containing a vapour-phase corrosion inhibitor (VCI).


Rustilo 66 VCI has been specifically designed for simultaneously cleaning and protecting ball and roller bearings. It is also suitable for the protection of all types of delicate or highly finished engineering products, particularly those, which contain moving parts and cannot be protected with greasy film coatings.

Rustilo 66 VCI can be applied by immersion in a suitably designed treatment tank, which should be covered when not in use. It can also be applied by spray.


Castrol Rustilo 66 VCI Neat Corrosion Preventive Oil Advantages:

  • Free from hydrocarbon solvents, supports compliance with the EC Solvent Directive (1999/13/EC).
  • Heavy metals free (for example Barium), which may help to fulfil aspects of legislative requirements and waste treatment requirements that specify that these chemicals are excluded.
  • Additional rust prevention through Vapour Corrosion Inhibitor. The maximum protection is achieved in hermetically sealed packs (safe packs).
  • Contains no additives which inhibit the even distribution of oil and grease (e.g. silicone)
  • Very good age resistance enables long service life and ensures the best cleanability even after temperature exposure.
  • Compatible with most mineral oils and greases
  • Shows very good filtering properties
  • If required protective films of Rustilo 66 VCI can be removed by using a petroleum solvent or alkaline process cleaner, all available from Castrol.

The claims on film thickness and consumption are average values. These are valid for smooth surfaces with good drain-off characteristics and simple geometries without holes or recesses.  “Indoor storage” describes the storage of ferrous components in closed store rooms having a relative humidity of 60%. Increased protection times could be achieved when treating finished surfaces or storing the parts in a sealed pack.


To avoid product deterioration always keep the container/drum tightly sealed. Store the product in a cool, dry place away from direct sunlight. Prevent exposure to frost and avoid water ingress. For optimum product stability, it is preferable to store the product indoors between 5°C and 45 °C / 41°F and 113°F. The influence of temperature may cause some cloudiness, which is reversible and does not have an impact on product quality or corrosion protection performance in most instances.
