Penrite Shelsley Heavy engine oil is a low detergent solution for vehicles manufactured between 1920 and 1950. This oil contains additional corrosion inhibitors to protect against rust and corroding during lay-up and extended periods of non-use.
Shelsley Heavy engine oil is designed especially for vintage vehicles that originally specified a ‘heavy’ grade oil or a SAE 50, and provides better cold circulation and higher hot oil pressure than a ‘straight’ or monograde oil.
