Preventive Maintenance
Item 1
Check the oil level daily before starting the engine.
Add oil, if necessary, to bring it to the proper level on
the dipstick.
NOTE: If the engine has just been stopped, wait
approximately twenty minutes to allow the oil
to drain back to the oil pan before checking the
oil level.
Select the proper grade of oil in accordance with the
instructions given in the Lubricating Oil Specifcations.
It is recommended that new engines be started with
100 hour oil change periods. The drain interval may
then be gradually increased, or decreased, following
the recommendations of an independent oil analysis
laboratory or the oil supplier (based upon the oil
sample analysis) until the most practical oil change
period has been established.
Item 2
Change the engine oil filter elements and gaskets each
time the engine oil is changed. Any deviation, such as
Items 3 and 4
changing filters every other oil change, should be
based on a laboratory analysis of the drained oil and
used filter elements to determine if such practice is
practical for proper protection of the engine.
Make a visual check of all lubricating oil lines for
