As far as I know, all modern cars shut off the fuel injectors when you let off the gas but stay in gear (i.e. on the overrun), until the RPMs get below a certain point (e.g. 1500 RPM).
What does the S2 RX-8 do? Does it shut off the fuel injectors, too? If it's not burning fuel, what happens to the oil that gets injected? Does it just accumulate and/or get blown out the exhaust? If that's the case, does that mean I should keep engine braking to a minimum for the sake of the catalytic converter?
I never downshift for the sole purpose of slowing down, but I will sometimes let off the gas way early and engine brake if I know I'm going to have to slow down ahead, especially while going down a hill. Just wondering if I should change that habit.
