The lubrication
systems
of your new vehicle are filled with high quality oils.
You should alway s use a high quality oil of the correct viscosity ran ge in the
engine, gearbox and rear axle during subsequent maintenance operation s or when
topping-up. The use of oils not to the correct specification can lead to high oil
and fuel consumption and ultimately to damage to the engine, gear box or rear
axle components.
Oil to the correct specification contains additives which disperse the corrosive
acids formed by combustion and also prevent the formation of sludge which ca n
block oilways. Additional oil additives should not be used. Servicing intervals mu st
be adhered to.
Engine Use a well-known brand of oil to B.L.S. OL.2 or MIL-L-2104B or A.P.I. SE
quality, with a viscosity band spanning the temperature range of your localit y.

*Clean fuel pump filter (68).
*Chec k fuel system for leaks, pipes and unions for chafing and corrosion.
