Lubrication
General
The engine and other lubricating systems are filled
with high-performance lubricants giving prolonged
life.
CAUTION: Always use a high quality oil of the
correct viscosity range in the engine. The use of
oil of the incorrect specification can lead to high
oil and fuel consumption and ultimately to
damaged components.
Oil to the correct specification contains additives
which disperse the corrosive acids formed by
combustion and prevent the formation of sludge
which can block the oil ways. Additional oil additives
should not be used.
Always adhere to the recommended servicing
intervals.Engine oil viscosity
The above chart indicates the ambient temperature
ranges which each engine oil viscosity is suitable for.
Engine oil - V8 - Not North America
Use a 5W/30, 5W/40, 5W/50, 10W/30, 10W/40,
10W/50 or 10W/60 oil meeting specifications ACEA
A1 or A2, having a viscosity band suitable for the
temperature range of your locality.
Engine oil - V8 - North America
Use a 5W/30, 5W/40 or 10W/40 oil meeting
specifications API SH or SJ, having a viscosity band
suitable for the temperature range of your locality.
Engine oil - Td5
Use 5W/30, 5W/40, 5W/50, 10W/30, 10W/40, 10W/
50 or 10W/60 oil to specifications ACEA A1/B1,
having a viscosity band suitable for the temperature
range of your locality.
Note: Where oils to these specifications are not
available, oils to specifications ACEA A3/B3 or A2/
B2 may be used but use of these oils may have an
adverse effect on fuel economy.
Note: Where oils to these European specifications
are not available, well known brands of oil meeting
specifications API SH or SJ may be used.
