Lubricants for your Routemaster

John Pryer (RM1152) has recommended these lubricants for Routemasters and uses them himself. All are available from Morris Lubricants which is a company that has earned a very high reputation from classic vehicle owners as well as operators of large fleets of modern commercial vehicles. His advice is based on a former representative of Morris Lubricants called Graham King.

The advantage of this advice is that only four lubricants are needed for your bus.

*My information that this oil is suitable for AEC and Leyland engines (if fitted with an oil filter) as well as the more modern replacement engines, but in the latter case, check with your engine manufacturer
