Engine Oil Requirements — Diesel
Engines
Checking Oil Level
To assure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop.
The best time to check the engine oil level is about
5 minutes after a fully warmed engine is shut off or
before starting the engine after it has sat over-
night.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level between the MIN
and MAX markings on the dipstick. Adding one
quart (0.95 liters) of oil when the reading is at the
MIN mark will result in a MAX reading on these
engines.

Selecting Engine Oil
Viscosity: Grade 15W-40 is recommended for
temperatures between +35°C and
Oils of the SAE 5W-30 grade are preferred when
the minimum temperature consistently falls below
10°C. If SAE 5W-30 grade is not available, then
SAE 5W-40 grade is acceptable.
Oil Quality: Use only Diesel Engine Oils conform-
ing to API (American Petroleum Institute) Quality
CH-4 or ACEA class B4.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact your dealer,
service station, or governmental agency for ad-
vice on how and where used oil and oil filters can
be safely discarded in your area.
Drive Belts — Check Condition and
Tension
At the kilometers indicated in the maintenance
schedule, all belts should be checked for condi-
tion and proper tension. Improper belt tension can
cause belt slippage and failure.
Belts should be inspected for evidence of cuts,
cracks, or glazing, and replaced if there is indica-
10°C. tion of damage which could result in belt failure. If
adjustment is required, the belts must be adjusted
according to the specifications and procedures
described in the Service Manual. Low alternator
belt tension can cause belt failure. A special tool
is required to properly measure tension and to
restore belt tension to factory specifications.
Also check belt routing to make sure there is no
interference between the belts and other engine
components.

Spark Plugs

Spark plugs must fire properly to assure engine
performance and emission control. New plugs
should be installed at the specified mileage. The
entire set should be replaced if there is any
malfunction due to a faulty spark plug, malfunc-
tioning spark plugs can damage the catalytic
converter.

Engine Air Cleaner Filter

The engine air filter should be inspected periodi-
cally and replaced as recommended in the main-
tenance schedule.
If the vehicle is driven frequently under dusty or
severe conditions, the filter element should be
inspected periodically and replaced if necessary.
