OIL IDENTIFICATION LOGO

A Iogo (symbol) is used on most oil containers to help you select the
oil you should use. The top portion of the logo shows the oil quality by
API designations such as CJ4 or others. The center portion of the logo
shows the SAE viscosity grade, such as SAE
viscosity on the low temperature side.).
You should look for this logo on the oil container, and use ONLY oil
containing the logo.

CHANGE INTERVALS

The oil and oil filter change intervals for your engine are based on
the use of recommended oil quality and viscosity, as well as high-
quality filters such as Isuzu genuine oil filters. Using oil other than
r e c o m m e n d e d , o r o i l a n d f i l t e r c h a n g e i n t e r v a l s l o n g e r t h a n
recommended, could reduce engine life. Damage to engines due to
improper maintenance or use of incorrect oil quality and/or viscosity is
not covered by the new vehicle warranty.
Your engine was filled with a high-quality engine oil when it was
built. You do not have to change this oil before the first recommended
change interval. Oil and filter change intervals depend on how you use
your vehicle. For information on the proper oil and filter change
intervals, refer to the maintenance schedule in this section.

ENGINE OIL ADDITIVES

Engine oils contain a variety of additives. Your engine should not
need any extra additives if you use the recommended oil quality and
change intervals.
