Under certain conditions of temperature and humidity, water can be present in fuel in sufficient
quantities to create ice formations within the fuel system. To prevent this, add Anhydrous ISO-
PROPYL Alcohol to the fuel supply in quantities not to exceed 3
of total fuel volume per tank.

Before every flight, check engine oil level and replenish as necessary.
The oil filler cap access door is located in top cowling. Any lubricating oil must conform with Con-
tinental Motors, Inc. Specification MHS24 to be acceptable for use in engine. See Continental
Motors, Inc. Maintenance and Operators Manual for specifically approved products.
During the engine break- in period, Nondispersant mineral oil conforming to SAE 51 966 shall be
used. However, if the engine is flown less than once a week, a straight mineral oil with corrosion
preventative MIL-C-6529 for the first 25 hours is recommended. After the first 25 hours of the
airplane’s time in service, the oil and oil filter must be changed and a new supply of Continental
Motors, Inc. specification MHS-24 (latest revision) ashless dispersant oil must be used. At 50
hours of time in service, the oil and oil filter shall be changed. Discard the old filter and replace
with new. Check discarded oil for evidence of metal particles. Thereafter, the oil and oil filter must
be changed at every 50 hours of time in service.
At the first oil change, the engine and related accessories including the magnetos, starter, alter-
nator, engine driven fuel and oil pumps, oil cooler, and propeller governor, should be inspected
for oil leaks and security.
Your Authorized Mooney Service Center will change engine oil in addition to performing all other
service and inspection procedures needed when you bring your airplane in for its 50-hour;
100-hour, or annual inspections.
Excessive oil sludge buildup indicates that the oil system needs servicing at less
than 50- hour intervals.
-CAUTION-
When changing or adding oil, the following grades of oil are recommended:

-NOTE-
The first time the airplane is filled with oil, additional oil is required for the filter,
oil cooler and propeller dome. This oil is not drainable on subsequent oil
changes. Added oil is mixed with a few quarts of older oil in the system.
* Refer to the latest edition of Continental Motors, Inc. Maintenance and Operators Manual for
approved brands of oil.

INDUCTION AIR FILTER
The importance of keeping the induction air filter clean cannot be over- emphasized. A clean
filter promotes fuel economy and longer engine life.
