Classic Sport 20w50 is a high performance SAE 20w50 semi synthetic multigrade engine oil. Made with enhanced performance additives and shear stable viscosity index improvers in synthetic and mineral base. It is formulated with full ZDDP (zinc/phosphorus).
• Uses latest lubricant technology to engineer a premium semi synthetic multigrade for high performance classic engines.
• Incorporation of high levels of synthetic base fluids provides increased protection under arduous conditions of load and temperature.
• Maintains high oil pressures and reduces oil consumption.
Currently the HPX 20/50 Semi Synthetic Engine Oil is not available. There is a possibility that HPX will be discontinued. I have worked with Millers Oils for many years, classic cars and race cars and I can strongly recommend this oil for your Alfasuds.
