Mazda RX-8 Engine Problems

BUY the RX8. Rotary engines are typically heavier on fuel than a four-cylinder engine, and your V8 comparison is probably correct. They have also been a little heavier on oil than a piston engine, but that's not a problem. The RX8 is a high-performance sports car and needs oils that protect it against hard driving.

No, the Mazda RX-8 sold in Australia only came with an updated version of the 13B rotary engine.

From what I can gather, the only production car to use the three-rotor 20B rotary engine was the Mazda Eunos Cosmo, built between 1990 and 1995 and sold exclusively in Japan. But many race cars have used 20B or triple-rotor engines, and they remain a bit of a holy grail engine for Mazda rotary enthusiasts.

For the record, the first Japanese car to win the Le Mans 24-Hour race was a Mazda 787B in 1991, using a four-rotor rotary engine of 2.6 litres. It was also the first (and only) time a vehicle without a reciprocating piston engine had won Le Mans.
