A car engine that burns oil not only wastes oil, but can damage spark plugs, which will end up in ignition system problem (engine misfire). Sooner or later it will affect the catalytic converter. Oil burning can and will also cause higher emissions, resulting in failed emissions tests due to excess hydrocarbon production.
All cars consume oil, at different rates depending on the engine model, driving patterns, engine load, maintenance history, age of the engine, driven km, motor oil quality, etc.
But excessive engine oil consumption should be taken seriously. If you know your car engine burns too much oil, get the problem diagnosed, before it cause some serious and costly damage.
On occasion could be a simple fix to the problem perhaps a damaged, aged gasket. However there are a few things you should know as follows.
The modern engines of late went thru some serious diet to increase horsepower and to reduce fuel consumption.
The law of physics has not changed, skinny piston rings and valve stems has one thing in common they reduce friction and fail to seal properly in the internal combustion engines of late.

Today most of the engines are turbo charged for efficiency reasons, in particular to reduce pumping losses. Turbo charging will increase the thermal heat load on the internal components. Once you got thin parts with double the heat exerted on them, equates to baked valve seals, clogged oil scraping rings with clogged piston oil drain holes.
The efficiency war on the internal combustion engines has produced some remarkable output at the expense of engine life and longevity.
For comparison see when I started working as a mechanic a 1.5 liter engine produced 74 horsepower on average. Today they can make as much as 230 horsepower in a moderate automobile.
As I said earlier the law of physics has not changed, the internal parts has been reduced to the bare minimum, so efficiency is the new magic word, unfortunately comes at the expense of reliability.
