Oilamatic, Inc. has been developing preoilers for several different engine applications. Recently, they have received FAA STC and PMA approval for preoiler installations on several aircraft. Prices of kits range from $1395.00 to $1545.00 and include all fittings, wire and hardware. Hoses must be procured separately.

The Oilamatic engine preoiler unit is a 12 or 24 volt electric motor driven pump. The custom designed and manufactured pump is plumbed into the engine oil system using special adapters so that oil is drawn from the crankcase and injected directly into the engine through the oil filter. The pump and motor are sized to provide adequate preoiling for a cold engine while keeping battery draw to acceptable limits. A check valve in the high pressure side isolates the pump from the engine once the engine is started and the pump is turned off. A dash mounted switch operates the preoiler (with Master switch on). The pilot can monitor preoiling on the engine oil pressure gage and turn the pump off as the starter is engaged. Typical installations provide oil pressure stabilized near the "bottom of the green" before start. No air is left in the system, and all parts are lubricated before their first motion. No matter how long the engine has been sitting, it is fully lubricated before start instead of after.

In summary, preoiling an engine can reduce that excess wear attributed to insufficient lubrication during start or from ill affects of long periods without operation. It is most comforting to see the oil pressure gage reading in the "bottom of the green" before the propeller starts turning.
