Hello,

I was just reading the FAQ that is posting in the new owners section of the forum. It recommended that for the first 600 miles that I should keep the rpm below 4000.

I was wondering, during this time what I should do about the carbon buildup.

Thanks

 

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.

Oil Change
every 3 months or 3k miles

 

I am very careful to drive slowly until my 2005 model is warm and I change the oil on schedule. I have found that the car now requires very little oil and I am getting 22 mpg. Is this normal.

Love my RX-8.

 

Depending on your driving habits i would check your every other gas fillup. Dian is right do not drive the car hard until it is warmed up.

 

I rev the **** out of my rotary 1 month after I got the car on a HPDE. The engine is much healthier for the high rpm carbon burn exercise!
