I've seen people that use the 15k mile amsoil oil and never check it because they think they only need to check it every 15k miles when they change it. They are confused at when they change the oil and only 2 qts come out and they definitely remember filling it with 5 qts.
All engines burn some amount of oil. Some less, some more, depending mainly on how well the rings seated during break in.
My truck burns about 1/2 qt or less in 5k miles during daily driving. If I go on a long tow(last year towed to AR and also NC) it burned about 1 qt during each of those couple thousand mile trips. There's a lot of factors.
My experience with Jap engines over 20+ years is that IF they are burning ANY oil, it's not detectable on the dipstick or sight glass. And I'm talking motorcycles, ATV's, cars, trucks and boat motors! All the Jap made engines I own never need oil added between changes and I always do long duration.
Now if you are talking domestic or even European engines, then I'd agree with you since ALL of these I owned needed a top up between changes, usually under a quart per 3k miles.
I'll live happily with 1 qt every 8000 miles burn on this Ram.
