Refer to the “Lubricant Information” section in the
latest revision of the Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations” for
detailed information. This manual may be found on
the Web at Safety.Cat.com.
The following are the preferred oils for use in most
Cat machine hydraulic
systems:
•
Cat HYDO Advanced 10 SAE 10W
• Cat HYDO Advanced 30 SAE 30W
• Cat BIO HYDO Advanced
Cat HYDO Advanced fluids have a 50% increase
in the s
tandard oil drain interval for machine
hydraulic systems (3000 hours versus 2000 hours)
over second and third choice oils when you follow
the maintenance interval schedule for oil filter
changes and for oil sampling that is stated in the
Operation and Maintenance Manual, for your
particular machine. 6000 hour oil drain intervals are
possible when using S·O·S Services oil analysis.
Consult your Cat dealer for details. When switching
to Cat HYDO Advanced fluids, cross contamination
with the previous oil should be kept to less than
10%.
