Engine Overheat Problems of Mazda RX8

Vehicle was bought new,2004. I have every oil change, every 2,900-3,000 miles and vehicle is perfectly maintained by the dealership ( harrelson Mazda -charlotte,nc ). Once 30,000 miles were put on the vehicle, engine began to fail ( stopped at red lights, stopped while on the highway,etc. ). After about 5 return visits to the dealership technicians, my engine was finally 'replaced' under warranty. Now my new engine has failed again at about 40,000 miles for the same reason as originally: Mazda specifically advises 10w-20 oil in this vehicle. But this is only to satisfy u. S. Epa standards. Everywhere else in the world, Mazda strictly advises 10w-30 oil, because anything less will allow engine to overheat and fail. I was never warned this. I was never advised this. I serviced vehicle by every reccomendation of Mazda, the owners manual, and my Mazda authorized dealership/technicians. My safety has been placed in jeopardy, solely at the fault of Mazda, for not notifying buyers that the engine had incorrect maintenance specifications,etc. Feel free to contact me anytime for further information, receipts of service,maintenance, and technician testimony. Thank you - greg t.
