Diagorenault is an oil analysis service which analyses the behaviour of transmission systems (engines, gearboxes and axles) and can be used to warn against faults in particular. The service can be used both preventively and curatively. As well as providing a complete and easy-to-understand analysis, Renault Trucks Oils can also advise users on what mechanical work they should have carried out.
