Trailer Information - Section S
Note: The recommended oil change period is 50,000
miles or every two years. When changing or adding
oil, the recommended oil is a 50w synthetic prefer-
ably and any quality brand oil is acceptable. The
acceptable oil weight range that may be used is 50w
Oil (minimum to 90 Weight Gear (maximum).
Note: It is normal for the oil to change color after a
few miles of use. Even a small amount of moisture
condensation can cause the oil to turn milky.
NOTICE
Most bearing failures are due to improper
maintenance. Be sure to inspect bear ings and
seals as noted in Section S-6B and refer to
the manufacturer’s literature included with
your trailer.
