Have a 2016 Sonata with a 2.4l engine. I use full synthetic oil and usually go about 3500 miles between oil changes. I did a hard brake on the highway and the oil pressure light came on then immediately went away. I checked the oil level and didn't even read low. I was about 2000-2300 miles from my last oil change and took 2 quarts to get it to a proper level, seems very excessive. I don't notice any leaks/smoke, PCV valve still rattles and seems in good condition, not sure if that much oil consumption is acceptable and what other causes it could be, thanks.
