For use where SAE40 oils were originally recommended. Suitable for older boxes of either straight cut, synchromesh or for overdrives (such as Laycock). Contains no EP additives which can cause serious damage to gearboxes containing yellow metals, or friction modifiers which can cause slipping in overdrives and pre-or gearboxes.
Please note that gearbox and engine viscosities are measured on different scales. This oil is measured on the engine viscosity scale and replaces SAE 40 and 20W-50 oils. It is approximately equivalent in viscosity to a 90-weight gearbox oil.
