Club 80-90 Forums

Four or five-speed gearboxes hold the same type of oil. Gl4 80-90 will do nicely. My 5-speed takes about 3,5 liters. The 4-speed takes a bit more to top up I think? Use a funnel and a hose. Put that hose through the enginebay and fill the gearbox. Helps keeping your garage clean.
