Every Supreme Lubricant pack shows its SAE viscosity grade and its API service category. This is what they mean.
- 20W Winter grade. The lower the number before the W, the more easily the oil flows at a cold start.
- 50 Viscosity at operating temperature (100 °C). A higher number means a thicker oil when the engine is hot.
- SL API category for petrol (spark-ignition) engines. Categories starting with S are for petrol engines; later letters are newer standards.
- CF API category for diesel (compression-ignition) engines. Categories starting with C are for diesel engines.
