Rotary Engine Flooding Prevention

Any trip that is too short for the engine to reach normal operating temperature (needle in middle of temperature gauge indicates normal temperature) should follow these steps to prevent flooding of the engine.

• With the engine already running,
• Raise the engine speed to 3000 RPM for 10 seconds
• Return to idle
• Turn off engine

The above are instructions to prevent flooding as described in your Mazda Owner’s Manual. We have been using a slightly different method that does not require holding engine speed at 3000RPM for an extended period of time. Here are the instructions:

• With engine already running,
• Raise the engine speed to 3000RPM
• Holding the engine speed at 3000RPM, turn the ignition key to the “off” position,
• While simultaneously depressing the gas pedal all the way down.
• After the engine has completely wound down, release the gas pedal.
