How many liters of engine oil does the Mercedes-Benz GLC260 require?
3 Answers
Mercedes-Benz GLC260 should be filled with 7 liters of engine oil. The Mercedes-Benz GLC260 is a mid-size luxury SUV under the Mercedes-Benz brand. The GLC series utilizes two types of engines: 1. A low-power version of the 2.0-liter turbocharged engine. This engine delivers 197 horsepower and a maximum torque of 320 Nm, with the maximum power achieved at 6100 rpm and peak torque available between 1650 to 4000 rpm. It features direct fuel injection technology and employs an aluminum alloy cylinder head and block. This engine is paired with a 9-speed automatic transmission (9AT). 2. A high-power version of the 2.0-liter turbocharged engine. This engine reaches its maximum power at 6100 rpm and generates peak torque between 1800 to 4000 rpm. Similarly, it incorporates direct fuel injection and uses an aluminum alloy cylinder head and block, also mated to a 9AT transmission.
My GLC260 just had its service, and the technician added 6.5 liters of engine oil. Actually, different model years can vary—for example, the engine tuning for the 2018 and 2023 models isn’t exactly the same. I remember during the last service, they first drained all the old oil completely, precisely measured 6.2 liters using a measuring cup, started the engine to run for a few minutes, and then checked the dipstick. The level was still slightly low, so they topped it up to 6.5 liters, which landed right in the middle of the marked range. It’s best to ask the technician to check the chassis number before servicing, as overfilling can make the engine feel sluggish, while underfilling can damage it. With precision machines like Mercedes-Benz, the right amount is crucial—never cut corners by eyeballing the oil level.
Maintaining a Mercedes-Benz GLC260 for three years with five service intervals, each requiring approximately 6.5 liters of oil. The 4S dealership uses genuine oil barrels—a 5-liter large barrel plus a 1-liter small barrel, which is just enough with a little leftover. Interestingly, during a deep cleaning service, they removed the oil pan to replace the sealing ring and ended up adding an extra 100 milliliters. The technician explained that more oil was needed to compensate for residual oil in the gaps of old components. It's important to note that engine temperature affects oil fluidity, and the dipstick reading is accurate only when the engine is cold. Newer models equipped with particulate filters are more sensitive to oil specifications, so it’s best to use the manufacturer-recommended 0W-20 low-ash oil as stated in the manual.
