Penrite GB30 is a multigrade gearbox oil designed specifically for vehicles that originally used the same oil in the gearbox as was recommended and used in the engine. Many vehicles manufactured in the fifties and sixties specified engine oil for use in the gearbox. Whilst this was convenient, a proper gear oil is a better alternative.
Penrite Gearbox Oil 30 is suitable for older boxes of either straight cut, synchromesh, epicyclic design or for overdrives such as Laycock. This gearbox oil contains no EP additives or friction modifiers.
