WARNING: This page is about a different car, the 2023 Mercedes-Benz GLC300, 2022 Mercedes-Benz GLC300, 2021 Mercedes-Benz GLC300, 2020 Mercedes-Benz GLC350e, and 2020 Mercedes-Benz GLC300. However, it is still accessible from the selected car via links, so may be relevant.

Engine 156, 166, 260, 266, 270, 271, 272, 273, 274, 282

	Risk of injury to skin and eyes due to handling of engine oil. Risk of poisoning caused by swallowing engine oil	Wear protective gloves, protective clothing and safety glasses. Do not fill engine oil into beverage containers.	AS18.00-Z-0001-01A
	Risk of injury. Skin or eye injuries may result when handling hot or glowing objects.	Wear protective gloves, protective clothing and safety glasses, if necessary.	AS00.00-Z-0002-01A

Warm up engine to normal operating temperature.
Allow engine oil to drain into a provided oil container.
When oil filler cap is opened and engine is at operating temperature.
Place oil container on a scales and weigh.
Note engine oil mass in kg and kilometer reading for the vehicle.
Pour engine oil into the engine.
Install remaining parts.
Perform measurement run.
Perform a measuring drive over a measurement distance of 250 km (if measurement carried out by workshop personnel) or 1, 000 km (if measurement carried out by customer). If the measurement is conducted by the workshop personnel, take into account the operating conditions of the vehicle at the customer's.
Warm up engine to normal operating temperature.
Allow engine oil to drain into a provided oil container.
When oil filler cap is opened and engine is at operating temperature.
Place oil container on a scales and weigh.
Note engine oil mass in kg and kilometer reading for the vehicle.
Pour engine oil into the engine.
Determine differential mass and measurement distance.
The difference in mass is calculated by subtracting the engine oil mass after the measuring drive from the oil mass before the measuring drive.
Calculate measurement distance.
The measurement distance is calculated by subtracting the kilometer reading before the measuring drive from the kilometer reading after the measuring drive.
Calculate oil consumption in "l" per 1000 km.
(Differential mass in kg x 1000 km)/(measurement distance in km x 0.85 kg/l) = oil consumption in liter "l" per 1000 km.
Install remaining parts.
