Mine has recently started leaving drips of oil on the garage floor. Valve covers leak and I think some other seal behind the t-belt cover is leaking.
The first owner (an older lady, so the accelerator was hardly used) put 20k miles a year on it. It was a Texas car, so it saw mostly highway and the engine led a fairly stress-free life. The second owner (my mother actually, so another older lady), did mostly highway as well but only put about 6k miles a year on it. I have records that date back to 2002 from the first owner showing 3k mile oil change intervals and dad did the same. The car had about 90k on it when I got hold of it and it was promptly switched to synthetic. It's used the same amount of oil since I got it.
To be exact, my last oil change done after 10k miles used just under three quarts of make-up oil. I bought two 4-quart jugs of Shell Rotella T6 5w40. Used one jug and one quart from the other jug for the oil change and used the other three for the make-up oil. It seemed to use a little more oil towards the end of that interval. I still haven't sent the oil sample in for analysis yet and I'm already over 5k miles into my current oil change.
