Hi all. I'm trying to get an emission exemption for my 1993 RX-7. My city allows for exemptions for "vehicles that are fueled by a mixture of gasoline and oil for purposes of lubrication". As we all know, the RX-7 uses the oil metering system to do just that, but I can't find any official Mazda source that says this. I have the service manuals and highlighted the diagram that shows the oil going to the injector (D-2 in the 1993 Service Highlights document), but I would really like a plain English description that says what it's doing to help present my case.

Does anyone have something official from Mazda, or at least from a trusted site that describes the system? For anyone that has the original owner's manual, does it say something in there, and is there a scanned copy anywhere?

Thank you for the help.

Perfect! Thank you so much for the quick reply.

Just print out the lubrication system pages of the 2nd Gen "Training Manual". It is technically for a 2Gen, but it is labeled "RX-7 Training Manual" so it should be good enough for your proof.

Downloadable copies of the 93 FSM are available in the 3rd Gen. FAQs. In it you will find a diagram of the oiling system which includes the OMP, lines and injectors which are specific to your car.
