In 2018, the GMC Terrain requires 0w-20 oil and holds 5.3 quarts. It is important to regularly change your oil, typically every 5,000 to 10,000 miles. Neglecting oil changes can lead to engine problems, so using high-quality oil is crucial for smooth engine performance. Issues with the oil can manifest as a foul burning odor, which should be addressed promptly to avoid potential engine failure. Poor-quality oil can result in decreased gas mileage and engine knocking sounds.
The recommended oil for the 2018 GMC Terrain depends on the engine type and varies in viscosity. The 1.5L 4-cylinder engine should use SAE 0W-20 oil, with the AWD model holding 5.3 quarts and the FWD holding 4.2 quarts. For the 1.6L engine, SAE 5W-30 is recommended, with a capacity of 5.3 quarts. The 2.0L 4-cylinder engine also requires SAE 5W-30, with the FWD holding 5 quarts and the AWD holding 6 quarts of oil.
0-20 translates to a measurement of 4.5 quarts.
