I have always used Duckhams Hypergrade 15/50 in my cars, every car I have owned actually. Mind you exxcept for the race engine I built for my old 1983 GJ GSR sigma, none of them have been any thing but stock.
I am wonering what was dodne to the engine I bolted into my wagon, as it doesn't seem to want to stop reving, with no valve bounce any where. Any how I like Duckhams.
