Remember how the gas companies used to give free gifts with fillups? (plates, glasses, car washes, etc) If your leak so bad that you are getting gifts from where you buy oil, you probably have a bad oil problem :)
Just kidding but - everything being relative - how much oil does it lose? Does it drop (do you see droplets under the car after it sat overnight) or get burned? How many miles do you travel to add what kind of quantity of oil?
You could replace the PVC valve (in case of burning), which is a very inexpensive DIY fix, if that is your problem. Not sure how easy the head gasket and pan gaskets are to replace on a Accort - that could also be your problem.
If you have to add a little to keep it topped off once a week, it is not a big deal. It is a 92 so one would assume you have decent number of miles on it. It is pretty much expected on an older car. Putting some oil in the car is most likely a lot cheaper than getting it fixed by your mechanic, even in the long run.
I drove a 72 Volvo for years just topping off with a little oil once a week. Unless you are getting gifts from your oil supplier, It may not be much of a problem.
