03 5at w/ 20,000miles on it. Last oil change I noticed I had some oil consumption (unusual, as I havn't had any in the past on this car....I can't remember exactly, but I believe I only had 3quarts left when I changed the oil). I kept an eye on it - after ~1000miles, I lost 1/2 quart.

Is this something I should be concerned about

 

That is within the normal range and I would not be concerned. Check your oil more often. Driving styles affect oil consumption. If you drive hard and floor it often and run it to the red line you will use more oil. If you drive easy, you use less. It is hotter in the summer, making oil thinner and thus also increasing consumption slightly. I recommend checking every other gas fill up and adding more in pint amounts to keep it near the full level. Then your remaining oil does not have to work as hard which also increases consumption. The lower it gets, the harder it is stressed, the more consumption increases. So it is better to keep it near full.

 

One other possibility is if you checked it after changing oil and before starting it, and it was full, part of the difference could be filling the filter (though it's very small). In any case, doesn't sound like cause for concern.

 

I don't want to be a jerk, but serious man. People are really refuse to use the "SEARCH" button.
