Penrite Classic 15W-50 is a multigrade engine oil for classic cars from 1950 to 1989 – a modern alternative to a straight 20W-50, with a wider viscosity range for easier cold starting and a broader operating temperature.
Penrite Classic Mini 20W-50 is a premium, high-zinc API GL-4 mineral oil for the classic Mini and other combined engine/gearbox (transmission-in-sump) applications, developed with the marque in mind to protect both engine and gearbox.
Penrite Classic Light 20W-60 is a multigrade engine oil for classic cars built between 1950 and 1989, especially higher-performance models such as MG and Jaguar. It offers strong film strength for period engines with dependable all-round protection.
Penrite Heritage LTM is a Light-to-Medium SAE 30/40 monograde, non-detergent engine oil for veteran and Edwardian machinery (around 1900–1920) with total-loss, wick-feed or early pressure-fed lubrication.
Penrite Heritage MTH is a Medium-to-Heavy SAE 40/50 monograde, non-detergent engine oil for veteran and Edwardian engines (around 1900–1920) with total-loss, wick-feed or early lubrication systems needing a heavier grade.
Penrite Shelsley Light 20W-60 is a low-detergent multigrade engine oil for vehicles built between 1920 and 1950 without full-flow filtration. Low detergency lets deposits settle rather than circulate, and added corrosion inhibitors protect engines that stand idle.
Penrite Shelsley Medium 25W-70 is a heavier low-detergent multigrade for 1920–1950 vehicles without full-flow filtration. The higher viscosity suits looser-toleranced or warmer-running engines, with corrosion inhibitors for cars in occasional use.
