RX8 Break In Procedures

RX8 Break In Procedures

Mazda's Guidelines

The Mazda RX-8 Owners Manual lists the following information for the break-in period of a new vehicle:

"No special break-in is necessary, but a few precautions in the first 1000 KM (600 miles) may add to the performance, economy, and life of your Mazda.

  • Don’t race the engine.
  • Don’t maintain one constant speed for long.
  • Don’t drive constantly at full-throttle or high engine RPM for extended periods of time.
  • Avoid unnecessary hard stops.
  • Avoid full-throttle starts."

A review of the Mazda RX-8 Service Manual Highlights revealed the following information regarding break-in:

"A fluorocarbon resin coating has been added to the trochoid surface (rotor housing) for improved initial break-in."

Racing Beat's Guidelines

The Mazda guidelines are reasonable and prudent. If you have any questions or uncertainly regarding the break-in period, we suggest you follow these official recommendations.

We receive many requests for our recommended break-in procedures. The following are Racing Beat's recommendations:

  • For the first 1000 miles do not accelerate under full throttle.
  • During the first 1000 miles do not exceed 4000 RPM.
  • For miles 1000-2000, expand the RPM upwards - but do not accelerate at full throttle.
  • Over 2000 miles, full throttle and high RPM is acceptable.

In summary, our guidelines offer a progessive method to increase the working loads placed on the engine.

Oil Change

The Mazda RX-8 Owners Manual indicates that the engine oil and oil filter be changed every six (6) months or every 7500 miles, whichever comes first. Racing Beat supports this recommendation.

Mazda recommends the use of SAE 5W/20 with a quality designation of ILSAC or SL.
