I've been on 4 forums for vehicles I own (wow, that few vehicles since the Internet became what it is).
I've heard many tales of woe from people about oil consumption and how the engine shouldn't consume blah-blah quarts of oil between oil changes.
I have never changed out the factory oil until at least 3000 miles.
New cars that I have owned after the year 2000:
My Ford I used full synthetic after the factory change at 5000 miles.
My Subaru I used full synthetic after the factory change at 4000 miles.
My Jeep I used full synthetic after the factory change at 6000 miles (now going with 8000 mile interval).
My wife's Toyota RAV4 V6 ran conventional until about 40K miles and now runs full synthetic, first oil change was at the recommended first interval.
Why do I mention all this?
NONE of our vehicles have EVER consumed oil between oil changes. We have had to add a little during the 'run in' with the factory oil, but after that nada/nothing/zip.
I am thoroughly convinced that people that change out the factory oil too early are the ones who end up with engines that consume oil between oil changes.
