The 2007 Chevrolet Equinox comes with a 3.4L V6 engine that requires 4.5 quarts of 5W-30 full synthetic motor oil. While it is possible to use SAE 5W-40 conventional oil in a pinch, it is not recommended due to its tendency to break down and its lower viscosity. Even though SAE 5W-40 may be cheaper initially, it can lead to issues in the long term. Both oils have the same viscosity at start up with the "5," but once the engine reaches operating temperature, the difference between "30" and "40" matters, and lower numbers are preferable. Investing a bit more in SAE 5W-30 oil can help keep your engine running efficiently for a longer time.
The typical engine in the 2007 Chevy Equinox, the 3.4L V6, holds about 4.5 quarts of oil. It's best to use 5W30 synthetic oil, unless it's colder than -20 F outside, then switch to 0W30 synthetic oil.
Here's a rephrased version of the text: "The motor oil with a recommended viscosity grade of 5w30.
Incorrect. The manual specifies using 4 quarts of oil when replacing the filter.
