    Has anybody else noticed the same?

    I am using 5W20 synthetic oil and the car now has 26K miles and it close to 2 years old. We bought it new.
    This is not a Mazda engine. It's a Ford engine so your experience with other Mazda engines is irrelevant. Mine chugs oil too. Can't find a good reason for it. Seems to run fine. I with they had a better dipstick. I can barely read it.

    Yes mine also consumes 1 quart of oil every 6mos or 6k which is when I do my oil changes. I use synthetic also. The engine is quiet and runs fine. The cx9 isn't the only car that does that.
