How much oil does a 2007 Kia Spectra hold?

In 2007, all models of the Kia Spectra are equipped with the same 2.0L 4Cylinder DOHC engine, which means that the oil capacity and type remain consistent across the board. To clarify, you should use 4.2 quarts of SAE 5W-20 full synthetic motor oil. While it is possible to temporarily use SAE 5W-30 in any weather conditions, or SAE 10W-30 in temperatures above 0 degrees Fahrenheit, it is not recommended for extended use. The reason behind this caution is that oil with a higher weight has greater viscosity, making it thicker and ultimately causing increased friction during engine operation. This can lead to accelerated wear and tear and premature engine failure over time. Therefore, it is advisable to always stick to the manufacturer's specified oil with the lowest weight, even if it means paying a bit more per oil change. In the long run, you will save money by ensuring your engine's longevity.
