Dynolite gear oil (1 litre). This multigrade oil replaces the SAE40 & EP90 commonly used in gearboxes. It is compatible with straight-cut and synchromesh gears, and safe for use in overdrive units. It does not contain any EP type additive that would destroy yellow metals such as bronze, copper or brass. This oil does not contain any friction modifier additives which can cause slipping in overdrive clutches and preselector gearboxes, such as Cotal or Wilson.
