how often do you check it? right before each change? or regularly?

the amount you're describing over the time frame is really not that bad considering the age of the car. i'm lucky that my oil level is what it is between changes but i've replaced every seal imaginable in the damn think and if you have higher miles you're just gonna have burn off. but yours isn't anything too alarming i wouldn't think. more than a quart every 5k is something to look at i think. but less is just something that happens

a quart per 4 months/5k isn't a huge deal. it's not good but it is a sign of something going wrong somewhere if you have no oil leaks especially.
