My BMW is pretty dirty. It just squeaks by 1983 emissions but I am not allowed to improve the fuel injection by California law. I wouldn't say CIS is doing it any favors.
That is why I was talking about the speed of the cars. If you drive a car hard you will use more energy and so more fuel. CIS cars are tuned pretty anemic, so they can't go so fast (accelerate as hard). I venture that since MFI has much more precise fuel control as far as pulsed injection that MFI has lower brake specific fuel consumption.
I think the oil and stuff old cars burns is probably more polluting than the part of the exhaust that is actually combustion products.
