Golden Film Classic Motor Oils are a specialist range of high quality, low detergent/dispersant monograde lubricants. These oils are suitable for use in naturally aspirated four stroke petrol and diesel engines and classic gearbox designs.
Golden Film Classic Motor Oils are recommended for use in veteran, classic and vintage cars, motorcycles, commercial vehicles and tractors, where engine design and tolerances prohibit the use of modern multigrade, high additive level oils. Modern dispersant additives keep combustion chamber contamination suspended in the lubricant, allowing full flow cartridge filters to remove it. Early oil filtration, usually in the form of a mesh gauze or strainer, is not efficient enough to remove this suspended material.
Golden Film Motor Oils are low dispersant oils and allow the suspended matter to drop harmlessly into the sump.
Golden Film Classic Motor Oils also have enhanced anti-foam properties ensuring optimised performance in motorcycle and automotive classic gearbox designs.
Engine Oil Grades
The viscosity rating of a multi-grade oil is broken down into two parts:
The number before the W is the `winter` or `cold start` rating. The lower the number the thinner the oil. This allows quick flow when the engine is started cold (cold crank). 90% of engine ware happens at this time due to the engine running in a dry state.
The second number is the viscosity rating of the oil at 100C. The higher the number the thicker the oil giving protection of `metal on metal` ware when the engine is hot.
So… Morris straight 30 stays the same viscosity at all engine temperatures. Where a 10W40 starts very thin then when the engine is at running temperature it gets thicker.
NOTE: Semi-Synthetic or Synthetic multi-grade oil MUST NOT be used in an air-cooled engine. Only mineral Multi-Grade oils.
