CAUTION
A sulfated ash limit of ≤1.0 percent has
been placed on all engine lubricating
oils recommended for use in PACCAR
engines. Higher ash oils can cause
valve and/or piston damage and lead
to excessive oil consumption. Failure
to comply may result in equipment
damage.
CAUTION
The use of a synthetic-base oil does
not justify extended oil change inter-
vals. Extended oil change intervals
can decrease engine life due to factors
such as corrosion, deposits, and wear.
Failure to comply may result in equip-
ment damage.
Additional information regarding lubricating
oil availability throughout the world is
available in the EMA Lubricating Oils Data
Book for Heavy-duty Automotive and
Industrial Engines. The data book can be

Aftermarket Oil Additive Usage
PACCAR does not recommend the use of
aftermarket oil additives. Today's high-
quality engine lubricating oils are very
sophisticated. Most oils already contain
precise amounts of additives blended into
the lubricating oil to meet stringent
performance requirements.
These oils meet performance
characteristics that conform to the lubricant
industry standards and are sufficient
protection when used according to the
recommendations. Aftermarket lubricating
oil additives are not necessary to enhance
engine oil performance and may in some
cases reduce the oil's capability to protect
the engine.
