vehicles to include the following:
Ambulances, police cars, and
emergency rescue vehicles.
Civilian vehicles such as light duty
pick-up trucks, SUVs, and passenger
cars that are used in military
applications.
Recovery vehicles such as tow trucks
and flatbed single vehicle carriers or
any vehicle that is consistently used in
towing trailers or other loads.
High use commercial vehicles such as
courier delivery vehicles, private
security patrol vehicles, or any vehicles
that operate on a 24 hour basis.
Any vehicle consistently operated in a
high sand or dust environment such as
those used on oil pipelines and similar
applications.
Vehicles that are regularly used for short
trips of 6 km or less.
The Oil Life Indicator will show you when
to change the oil and filter. Under severe
conditions the indicator may come on
before 10 000 km. The indicator won't
detect dust in the oil, so if you drive in a
dusty area you may have to change the
oil and filter sooner than every
10 000 km.

conditions listed above, it may be
necessary to replace your spark plugs at
more frequent intervals. For further
