Description Please call 01869 227062 for a suitable alternative. For use where SAE30 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-selector 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 30 and 20w-50 as well as some 80w-90 gear oils.
