Usually it's between 3 and 4 quarts of engine oil. I would just dump 4 into my 1990 CRX (Civic engine) and call it good; that was pretty good with the filter change.

The owner's manual for the older Civics specified 10W30 motor oil for the transmissions. Some very knowledgeable people feel that Honda MTL is too thin for the older ones like that. If you have it available, check your owner's manual to see what is called for in it.

Transmissions are about 2-2.5 quarts of fluid. They typically get filled until the fluid is at the bottom of the fill hole. Make sure to loosen the fill plug FIRST, because they are often on very tight for some reason. I used a 6-point 17mm/19mm wrench because there wasn't enough space to fit a socket and ratchet on my car. I used a "cheater" for extra leverage.

One final note on the transmission: Make sure the car is level when filling it. If the nose of the car is up in the air, you will underfill the trans because the fill hole is near the back. Input shaft bearings do not like it when you underfill the fluid--I killed two of them that way before I realized what I was doing.
