In Stock

Penrite Classic Medium is a premium mineral, 25W-70, high zinc, low detergent engine oil designed specifically for engines manufactured between 1950 and 1989.  This SAE 25W-70 grade oil can be used to replace SAE 40, with better results than using a 20W50. 

Classic Medium features a double layer of engine wear protection with high zinc and increased operating temperature viscosity, over older style multigrade oils or where SAE 40 monograde oil was specified by the manufacturer. It controls oil consumption and maintains oil pressure in older engines.

Penrite recommend this oil for engines in Rolls-Royce Silver Wraith, Silver Dawn, Phantom IV, V and VI, Silver Cloud I, II and III, Silver Shadow, Silver Shadow II and Bentley Mk VI, R Type, S1, S2, S3, T Type.

Penrite Classic Medium was previously sold in the UK under the name HPR 40.
