—CAUTION—
Assure that the additive is directed into the flowing fuel stream.
The additive flow should start after and stop before the fuel flow.
Do not permit the concentrated additive to come in contact with
the aircraft painted surfaces or the interior surfaces of the fuel
tanks.
Some fuels have anti-icing additives pre-blended in the fuel at the
refinery so no further blending should be performed.
Fuel additive cannot be used as a substitute for preflight draining
of the fuel system drains.
DRAINING MOISTURE FROM FUEL SYSTEM.
The fuel tanks and fuel strainer should be drained daily prior to first flight and after refueling to avoid the
accumulation of water or sediment. Each fuel tank is equipped with an individual quick drain located at the
lower inboard rear corner of the tank. The fuel strainer with a quick drain valve (refer to Figure 12-3) is
located on the lower left side of the firewall. Drain fuel tanks and strainer per the following:
1. Drain each tank through its individual quick drain located at the lower inboard rear corner of the tank,
making sure that enough fuel has been drained to insure that all water and sediment is removed.
2. Place a container under the fuel strainer drain. Drain the fuel strainer by opening the quick drain on the
strainer.
3. Examine the contents of the container placed under the fuel strainer drain for water and sediment and
dispose of the contents.
—CAUTION—
When draining any amount of fuel, care should be taken to
insure that no fire hazard exists before starting engine.
DRAINING FUEL SYSTEM.
Fuel may be drained from the system by opening the valve at the inboard end of each fuel tank. The drain
valve requires the drain cup pin to hold valve open. The remaining fuel in the system may be drained through
the filter bowl. Any individual tank may be drained by closing the selector valve and then draining as desired.
SERVICING OIL SYSTEM.
The engine oil level should be checked before each flight and changed after each 100 hours of engine
operation. During oil change the oil screen(s) should be removed and cleaned, and the oil filter cartridge
replaced. Replace oil filter at 50-hour intervals. Use a quality brand aviation grade oil of the proper season
viscosity. For information on the use of detergent oil, on the PA-28RT-201 airplanes refer to Application of Oil
and/or latest revision Lycoming Service Instruction Letter 1014. Detergent oil that meets Continental Motors
Corporation Specification MHS-24, is the only recommended lubricating oil for the PA-28RT-201T airplanes.
