The Classic range of oils are formulated for engines produced from the early fifties to the mid eighties that have micro-particle oil filters, typically made of paper or felt. They replace monograde SAE engine oils giving improved lubrication and reduced oil consumption.
This oil is ideal for engines where a 20W-50 was originally specified, as it provides better oil pressure when the engine is hot for prolonged periods. Suitable for many post-war engines, in particular high-performance vehicles such as Triumph, MG, Porsche, Jaguar, Ferrari, Alfa Romeo, etc. This oil is also recommended for cars using a 6 volt electrical system, where the starter motor requires minimum resistance.
