Lubrication
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
Engine oil viscosity / temperature ranges are
indicated in the following table:
a0W/30; 5W/30
b0W/40, 50, 60; 5W/40, 50, 60
c10W/30
d10W/40, 50, 60
Engine oil – Td4 engine
Use 0W/30 or 5W/40, 50, 10W/30, 40, 60 oil meeting
ACEA A3/B3 specifications, and having a viscosity
band recommended for the temperature range of
your locality. Where oils to these European
specifications are not available, well known brands of
oils meeting API SH quality should be used.Engine oil – K1.8 engine
Use a 10W/40 oil meeting specification ACEA A2 or
A3.
Engine oil – KV6 engine – Non NAS models
Use a 10W/40 oil meeting specification ACEA A2 or
A3.
Engine oil – KV6 engine - NAS models
Use a 5W/40 fully synthetic oil meeting specification
ACEA A3. Where oils to these European
specifications are not available, well known brands of
oils meeting API SH quality should be used.
Gearbox oil
Use of gearbox oils other than those specified may
result in serious damage to the gearbox.
Manual Gearbox – PG1 and Getrag
Use OPEL B 0400063 for refill or topping-up.
Automatic Gearbox – JATCO
Use Texaco N402 fluid for refill or topping-up.
Intermediate Reduction Drive
Texaco S5 75W90; Synthetic oil or equivalent,
meeting: API GL5
Rear Differential
Multigear 80W/90 ETL; Specification: API GL5
Gear linkage - Manual
Use grease containing 3% Molybdenum Disulphide.
General Greasing
Use Multipurpose Lithium Base Grease NLGI
consistency No. 2.
Bonnet latch
Lubricate cable and latch with oil.
