How many quarts of oil does a Corolla Dx hold at oil change?

HI. The fill cap will be 3 2/5 Quarts in the Corolla DX

4 quarts, 5 with filter change according to the book. Rule of thumb, buy 5 and once you drain and replace the filter, start by putting 3 and a half quarts in and check the level. If it's between the marks start the motor and run for 5 minutes then let it sit for 5 minutes and recheck the level. Top off half a quart at a time till you get the oil level between the full and add marks.
