How much oil does the 2012 Toyota Sienna take?

The 2012 Toyota Sienna comes with either a 2.7 liter 4Cylinder engine, or a 3.5 liter V6. The smaller of the two engines takeS4.6 quarts of SAE 0W-20 synthetic motor oil, while the larger takeS6.4 quarts of the same. In emergency situations where 0W-20 may not be available, it's possible to substitute SAE 5W-20, though it should be replaced with the 0W-20 as soon as possible. To understand why, we must first understand what oil weights mean. The first number (0 or 5) is the oil's viscosity at startup. The second (20) is viscosity at full operating temperature. Lower numbers are better, so 0W-20 will keep Your engine running more smoothly and efficiently. This leads to a longer engine life, and You may even see some additional miles per gallon in the meantime.
