2004 Mazda RX-8 engine problems

There is contamination in the oil. So much so that it is impossible to check the oil. I've gone 3000 miles and never been able to check the oil. Even after wiping the dipstick, simply putting it back recoats the dipstick, so that the oil level cannot be read. The dealer simply changed the oil, but did not fix the problem. They said mazda knows about this, but won't do anything about it. All letters to mazda-USA are ignored. Why does mazda ignore such a potentially serious hazard?

Tl*the contact owns a 2004 mazda rx-8. The contact stated that he took his vehicle in for a recall repair. The dealer and the manufacturer refused to repair his vehicle because he did not have a recall notice present. The contact stated that he never received a recall notice. Since that time, his vehicle has experienced a loss of power, excessive air consumption, and poor mileage. The # of cylinders is 0 because the vehicle has a rotary engine. The current mileage is 71,000 and failure mileage was 65,000.
