Ok, to clear some of this oil consumption up, I’m going to throw my 2 pennies in and probably not talk about it anymore.
Cars burn oil, some more than others but they all burn oil, it’s a fact. My 3.6’s manual even says it does, which is weird for a manufacturer to admit. My car consumes a minimal amount (I don’t notice any gone), I use Amsoil but I don’t think that has anything to do with it.
As a car owner, you should always check your oil. I check mine at least once a week, mostly out of habit because my 4th gen lost more than it was supposed to.
If you do an oil change, do you prime your filter? Do you start the car after you’re done, turn it off and check your oil level later or do you just pour oil in it until the dipstick level is up to your satisfaction?
If someone else does your oil changes, do you physically check your oil level on a flat surface to make sure they did their job correctly? If not, you should.
