RX-8 Break-In

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.
