The correct lubricant is critical to obtaining maximum life from your machine. Regular oil testing combined with machine servicing is required. Diesel with high sulphur content depletes the engine oil additives which will reduce the engine oil life. Note: This is just a guide and the manufacturer’s recommendations should be consulted.
