Golden Film SAE 40 Classic Motor Oil

Golden Film SAE 40 Classic Motor Oil is a specialist high quality, low detergent/dispersant monograde lubricant from Morris Lubricants, suitable for use in naturally aspirated four stroke petrol and diesel engines and classic gearbox designs. Formulated for veteran, classic, and vintage vehicles where engine design and tolerances prohibit the use of modern multigrade, high additive level oils, it provides reliable lubrication without the risks associated with modern dispersant additives in older engines.

As a low dispersant oil, Golden Film SAE 40 allows suspended combustion chamber contamination to drop harmlessly into the sump rather than remaining suspended in the lubricant — an important characteristic where early filtration systems such as mesh gauzes or strainers are fitted. With enhanced anti-foam properties for classic gearbox applications, it is also an ideal choice for lightly loaded diesel engines in canal boats, watercraft, and older generators such as Lister and Perkins units, where it can dramatically reduce the likelihood of bore glazing.
