What is the individual compression readings on each cylinder? Do they improve with the addition of oil?

I just tested my EF with 223,000k's and got 180psi all round +- 2psi. That is an excellent reading. That is very close to new car compression. Anything below 146psi is considered rebuild time for a falcon.

Make sure you test with all plugs out (to speed up rotation) and with throttle at WOT.
