DETAIL
In order to ensure full engine protection and consistent engine start-up in cold weather conditions it is important that Land Rover oil viscosity recommendations be followed. It is particularly vital when temperatures fall below freezing, 0°C (32°F), that the recommended 5W/40 or 5W/30 oil be used to ensure that proper cranking speeds can be obtained.

Information published in the Service Manual for NAS vehicles in some editions may be confusing. In some cases the entire range of engine protection is not shown on the NAS page. Refer to the information below for accurate engine oil protection information.

ACTION REQUIRED
USE ONLY RECOMMENDED MULTI-GRADE OILS.

FOR WINTER DRIVING WITH TEMPERATURES ROUTINELY BELOW FREEZING, A MULTI- VISCOSITY 5 WEIGHT OIL IS REQUIRED. 5W/40 Oil IS RECOMMENDED.
