Bought a 1989 RX-7 - You suggest adding 2 stroke oil to gas - How much
   per gallon ?
   Plan to drive it for a while and then use the engine in a homebuilt -

   Good idea. A car that old the nylon lines feeding oil to the apex seal are brittle.

   2 Oz per gallon will do it. Walmart sells it by the gallon.

Rotors magazine (a YouTube channel for people who run rotarys in cars) recommend premixing at the rate Paul said 2oz per gallon with the caveat a little less is ok of your not running, with a little more if your running hard. One of the reasons is that the fuel injector has a wider spray path than the stock oil injectors, and supposedly better lubricates the engine. Also, your not using engine oil for lubrication the engine has a supply of clean oil. I don't know enough about the engines (yet) so I wasn't sure about that last part. I'm sure Mr Lamar knows, and if that would be applicable for aircraft use.
