George is correct.   The oil is normally about an inch ABOVE the oil pan top 
in the RX-8.  It has caused a bit of oil foaming problems and gives false 
low oil warnings at higher speeds (>80 mph) in the RX-8.  Mazda fixed this 
problem by some unknown means (didn't replace the pan).

I used an RX-7 pan on my Renesis because I didn't like the 'look'  of the 
RX-8 oil level.  This require some mods to the pan.

>>Lynn,
