2007 Toyota 4Runner: What is the oil type and capacity?

Each trim level of the 2007 Toyota 4Runner is fitted with either A4.0L V6 engine, or a larger 4.7L V8. The engine option You have affects the capacity -- the 4.0L useS5.5 quarts, while the larger 4.7L useS6.6 quarts. However, the motor oil type remains the same; both require the use of SAE 5W-30 full synthetic. In emergency situations, it's possible to substitute SAE 5W-40, but this is not recommended, especially over the long term. The reason for this deals with viscosity. The higher the numbers in an oil's weight, the thicker the oil will be. This introduces friction to the engine, which causes the motor to work harder for the same output. Over time, this leads to premature engine wear and tear, so it's always wise to use the oil recommended by Your manufacturer with the lowest numbers.
