How much oil do you put in a 2003 cavalier 4 cylinder 2.2 liter engine?

my 2.2L 1999 cavalier takes 3.7 quarts of 5w-30 oil. use castrol at wal-mart stores. look at owners manuel or go to autozone.com.

The 2003-2005 cavaliers have the 2.2 Eco-tec motor which takes 4 and a half to 5 quarts of oil. the Idea was to give it more miles between oil changes but with the new filter they used it really should still be changed every 3,000 miles.
