Please keep your service & maintenace paperwork. Ensure that the compression is alway within tolerance, if it is low or you start to have problems with repeat trips to service, make sure they tell you exactly what is wrong and how they are going to fix it. But enjoy it, it is a nice ride....

Mazda recommends 5W20 for North American RX8's and 5W30 everywhere else. Both are a fine choice. DO NOT USE SYNTHETIC OIL. Mazda warns against this and will decline engine warranty if you use synthetics. This is because most synthetic oils are designed to reduce oil "burn-off" and since the rotary engine uses oil injection into the combustion chambers you NEED the oil to burn-off as cleanly as possible.
Older rotary engines had shorter life spans due mainly to apex and side seal wear, but the Renesis rotary of the RX8 should last you 200,000+ miles if properly cared for. This includes oil changes every 3000 miles. This includes preventing carbon build-up by running the engine to red-line frequently and/or taking long highway drives. This includes checking your oil levels every couple fuel tank-fulls and topping up as required. This includes warming up the motor a bit before driving and warming fully before pushing it past 4K - 6K RPM. This includes not shutting down the motor "cold" as it can cause flooding (which also thins the oils with gas). And NEVER let a rotary engine overheat. This will warp the rotor housing and bye-bye motor.
Rebuilds are not really any more expensive than piston engines provided the rotors and housings aren't damaged or warped. A simple rebuild can cost between $500 - $1000 plus removal/installation labor. A factory rebuilt motor sells for around $2000 the last time I checked...a good option if the original motor has damage or warpage.
I found this from a rotary mechanic....

Thanks for that informative post. I'm having the same problem, pinhole leak. Would you please tell me where you found that part, 14-7102, for $120? Thanks a lot.
