R40 Castorene racing oil is a Castor Oil based blend incorporating synthetic lubricants and additives. This lubricant has naturally high film strength and resistance to seizure. It contains vegetable oil and minimizes the risk of thickening or lacquer formation. Inhibitors derived from aircraft gas turbine engine technology give stability and oxidation resistance. Oil thickening and lacquer formation is reduced even in hot running engines, allowing the oil to be used for longer periods than normally associated with castor-based products. Fully soluble in alcohol fuels and ideally suited for use in both air and liquid cooled racing engines running on methanol or methanol based fuels. Petrol and methanol compatible castor based racing oil. 1 litre.
