No modern car should be burning oil at noticeable amounts. For example, my mom had a 1985 Nissan Maxima, and the engine wasn't burning oil. There is zero excuse nowadays.
If someone is at the point where they're physically incapable of checking their oil, there's a [censored] good chance they shouldn't be driving.
Also, plenty of high performance engines burn a little oil, it's all a matter of engine design. Ask anyone who's owned an S4, they all burn a little oil. Different engine designs have different seal types, clearances, etc.
For example, my mom's Jeep has the 4.0 I6 and it has never burned a drop, dipstick is still right where it was after the last change when I change it at 5k miles. My Jeep however, burns a little (usually about a 1/2 quart in 6k between changes, but it varies based on driving style). Around town, it'll burn almost nothing. It'll burn about a quart in 6k of steady highway cruising. If I'm really beating on it (lots of high rpm engine braking, etc.), it'll burn more, probably close to a quart in 2k miles. Some of it ends up in the catch can (valve cover baffles under the PCV aren't great), some gets burned, mostly through the valve seals, I think. The seals aren't worn out, they're just not a super-tight, perfect seal to start with (it's burned exactly the same amount since the heads were re-done).
After 25 years of driving an AMC I6, my mother forgot about checking oil Their 4.2 and 3 4.0s never used a drop of oil. My father, a truck driver, checks the oil every time he drivers ... anything.
Their 2008 Wrangler started drinking oil. He never drove it, so he never thought to check it. She never checked it because she was used to the AMC I6s for the last 25 years that never used any oil.
They were surprised when I checked the oil and it only had 3 quarts in it! After that, they started checking every week. Though, towards the end, they didn't bother checking and just dumped a quart in every other week.
What's funny now is, they both check the oil in the Focuscape (2013 Escape) twice a week. Luckily, the Focuscape isn't using any oil.
