Penrite Classic Light engine oil 20W/60 can be used to replace SAE 30 and 20W-50 grades. It was previously sold in the UK as HPR30.
This grade of oil was especially made for engines manufactured between 1950 and 1975, including most high performance vehicles such as MG, Jaguar, Triumph and Porsche. It is also suitable for cars running six volt electric systems and motorcycles, where cranking / kick start speeds require an engine to turn over with minimal drag. Penrite Classic Light engine oil is also suitable for motorcycles of the same vintage.
This broad spectrum multigrade Penrite oil ensures that starter motor cranking loads are reduced to comparible levels of a monograde oil, whilst hot oil pressure is improved.
