Comma 15w40 Mineral Multigrade Oil
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 15W40 starts 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.
