Sorry this item is out of stock

A low detergent engine oil intended for vehicles manufactured between 1920 and 1950.  Shelsley Heavy is a 40W/70 multigrade oil designed for older vehicles originally specifying a Heavy Grade Oil or a SAE 50, and will provide better cold circulation and higher hot oil pressure than a 'straight' or monograde oil.

Shelsley Heavy is recommended for use in large engined vehicles operating in high ambient temperatures, or in vehicles with oil consumption problems. It's ideal in large capacity sleeve valve engines fitted to such makes as Minerva, Mors, Knight and Daimler.

Shelsley Heavy is a good choice for early vintage (pre 1950) motorcycles, incorporating sight glasses, pilgrim oil pumps and total loss lubrication systems. It is suitable for use in motorcycles fitted with a wet clutch.

The oil contains a "Tacky Additive" so that when vehicles are laid up, the engine oil doesn't run off the internal surfaces. This combined with an increased level of rust inhibitor, provides protection against corrosion and deterioration when the engine is not used or in storage.


If you are concerned about the sensibility of multigrade oil in vintage engines, please call us to discuss.
