CHANGING ENGINE OIL AND FILTER
Under normal operating conditions, the engine oil and filter must be changed every
100 hours or every 12 months whichever occurs first. Use of premium quality oil
and filters is recommended. The oil and filter should be changed more often if the
engine is operating in severe conditions, such as dirty areas, or during cold
weather. No oil additives or break-in oil are recommended.
CAUTION: Do not operate the engine with the oil level below the
bottom of the dipstick or ‘Add’ mark on the dipstick, or above the top or ‘Full’
mark on the dipstick.
Engine Oil Level Check
The engine oil level should be checked daily. It is recommended that the oil be
checked just before the engine is started for the first time for the day. The oil level
should be between the ‘ADD’ and the ‘FULL’ marks on the dipstick.
Adding Engine Oil
It is normal to add some oil in the period of time between oil changes. The amount
will vary with the severity of operation. When adding or replacing engine oil, be
sure the oil meets or exceeds the recommended specification.
Engine Oil Quality
To achieve proper engine performance and durability, it is important that you use
only engine lubricating oils of the correct type in your engine. Quality oil also
provides maximum efficiency for crankcase ventilation systems, which reduces
pollution.
Engine Oil Recommendation
Motor oils meeting ILSAC (International Lubricant Standardization & Approval
Committee) GF-4 standards. The GM spec for this oil is 9986231. Motor oils
meeting this spec receive the API (American Petroleum Institute) starburst symbol:
