Millers Oils Classic 4T 20w50
- Incorporates modern additive technology with period viscometric to provide the optimum lubrication characteristics
- The modern technology ensures an oil which will meet up-to-date specifications, along with meeting the 'period' performance requirements
- Suitable for higher mileage applications where oil consumption is a problem as high viscosity helps to reduce oil loss and leakage
Classic 4T 20w50 is a mineral oil for engines/transmissions (where applicable) requiring a 20w50 viscosity. The traditional technology used is ideal for the older air-cooled engines. The formulation includes ZDDP for maximum protection. Includes a constant high-friction profile for wet clutch performance meeting the JASO MA2 specification.
Use as received for engine lubrication of primarily pre-1980 vehicles, which were developed on the multigrade oils of this era.
