In markets  where oils to the  above  specifications  are not  available  use products  to MIL-L-2104D or API  CD. 
Under  severe  operating  conditions,  eg. 
off road in mud,  airborne  sand, dust, operating  at high  speeds  in high 
ambient  temperatures  above 40°C 
or continual stoptstart operation,  the oil and filter  change  period should 
not  exceed 
5000 km (3000  miles).  Continuous off road operation  in mud,  dust and wading  conditions 
requires  a monthly 
oil and  filter  change.  Failure to adhere  to the  recommended service and  operating 
instructions  may result 
in premature  engine wear or damage.

							CAPACITIES 
The following  capacity figures are approximate  and are provided as a guide  only. All oil levels must be set 
using  the dipstick 
or level  plugs as applicable. 
Engine  sump 
oil ................................................................ 6,OO litres (10.56  pints) 
Transfer  box

Anti-freeze 
Ethylene  Glycol based anti-freeze  (containing  no methanol)  with non-phosphate  corrosion inhibitors only are 
suitable 
for use in Tdi  engines  to ensure  protection of the cooling  system against frost and corrosion. No 
inhibitors  should be used. Only anti-freeze,  summer  and winter  even in climates  where anti-freeze is not 
necessary. 
One  part anti
-freeze,  one part water, i.e. 50% anti-freeze in coolant.  Complete  protection  below -36°C.  ~ 
See 
cooling  system section  26 for engine protection  information.
