Mentioned very specifically in section 8 (page 216), of the owner's manual of my altis ..
1ZZ-FE Engine
with filter - 4.2 ltr = 4.4 qt = 3.8 imp qt
without filter - 4.0 ltr = 4.2 qt = 3.6 imp qt
2NZ-FE Engine
with filter - 3.7 ltr = 3.9 qt = 3.3 imp qt
without filter - 3.4 ltr = 3.6 qt = 3.0 imp qt
2C Engine
with filter - 5.1 ltr = 5.4 qt = 4.5 imp qt
without filter - 4.4 ltr = 4.7 qt = 3.9 imp qt
The above mentioned data is also supported by my personal experience of all the three variants.
Hope it solves the puzzle.
