Engine Oil Additives
Do not add anything to your
engine oil. Oils of the recommend-
ed quality are all you need for
good performance and engine
protection.
Consult your dealer if you think
your engine has an oil-related
problem.

Engine Oil Change Intervals
The required oil and oil filter
change intervals vary considerably
between climates, geographical
locations, terrain and driving
conditions. The local-language
Maintenance Schedule booklet
provided with your vehicle
shows the oil and oil filter change
intervals required for your specific
area. Make sure to follow the
change intervals listed in the
local-language Maintenance
Schedule booklet and not those
listed in any other English booklet
that might be provided with your
vehicle.
The oil and oil filter change
intervals recommended in the
Maintenance Schedule for your
engine are based on the use of
recommended quality oils and
high quality filters. Using oil other
than those recommended, or
changing the oil and filter at long-
er intervals than recommended
could reduce engine life.
How frequently you have to
change the oil depends on your
driving patterns, engine rpm and
engine temperature.
Depending on your driving
conditions, the mileage interval at
which an oil change is necessary
can vary considerably.
