RECOMMENDED LUBRICANTS
Engine
In order to ensure the longevity and reliability of the vehicle, it is most important that only the specified
lubricants are used. It is an entirely false economy to try to save money by using lower quality oils, which may
break down before the next change interval and provide inadequate protection before the end of the term. High
oil consumption may also result.
Engine oil should meet Rover specification RES.22.OL.G4 or the European specification CCMC G4, and
have a viscosity band recommended for the local ambient temperature range, as shown in the following chart.
Where oils to these standards are not available, reputable brands meeting American specification API SG or SH
should be used.
Note that the viscosity rating is made up of two numbers; the first, identified by a 'W suffix is the winter (or low
temperature) viscosity grade, and the second number the summer or high temperature viscosity grade, i.e. a
20W/50 oil performs like an SAE 20 oil at low temperature and an SAE 50 oil at high temperature.
