The check engine light does not come on for low oil. The oil warning light would come on for that. I guess the CE light came on for some other reason and you then checked the oil. You have to get the code read to see what caused it.
How low was the oil on the dip stick when you checked it? What does it read on the stick after adding the quart? How many times did you check the oil in the last 450 miles?
Me, I check my oil level 4-6 times in 500 miles. I never let it get down more than an eighth-inch on the stick.
Get the code read and CHECK YOUR OIL EVERY SINGLE DAY until you get to know how much it uses! During the warmer months when I'm off work and driving a lot, I will check my oil every single day before heading out. That is how you avoid losing an engine.
I have 237,000 miles on my engine that has been using a semi-excessive amount of oil for the last 175,000 miles. It runs like a dream and I've never come close to losing the engine from low oil. Check your oil level every day. Check your oil level every day. Checking at every fill-up is not good enough. Check your oil level every day.

Edit- I don't know if I mentioned it, but CHECK YOUR OIL LEVEL EVERY DAY! It's so easy to do and you'll sleep a lot better.![]()
