What type of engine oil can be used for the Mercedes-Benz GLC260?
3 Answers
Mercedes-Benz GLC can use Mobil 1 or Castrol EDGE 0W-30 engine oil, as well as Mobil 1 Gold 0W-40 engine oil. Below is an introduction to engine oil: 1. Function of engine oil: Engine oil, also known as engine lubricant, serves multiple purposes for the Mercedes-Benz GLC engine, including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the 'blood' of Mercedes-Benz vehicles. The engine oil used in the Mercedes-Benz GLC consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance of the base oil, providing additional characteristics. These additives are a crucial part of the lubricant. 2. Composition and classification of engine oil: Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic oils. Mineral base oils are widely used and account for a large portion of the market (over 95%), but certain applications require the use of products formulated with synthetic base oils.
As an owner of a Mercedes-Benz GLC260, I always use full synthetic oil that must be Mercedes-Benz 229.51 certified. I recommend SAE 0W-40, which ensures quick starts in winter and provides excellent engine protection in summer heat, making it ideal for the M274 gasoline engine. My personal choice is Mobil 1 0W-40 because it meets the standards and maintains stability without burning oil during high-speed driving. Remember to change the oil every 8,000-10,000 kilometers or once a year—don’t skimp by using conventional oil. Mercedes engines are precision-built, and poor-quality oil can accelerate wear or even cause overheating. The grade can also be 5W-40, but 0W-40 is better for colder regions—always prioritize the certification label on the oil bottle. I frequently check the owner’s manual for confirmation, which gives me peace of mind while driving.
Choosing engine oil requires attention to technical details. The Mercedes-Benz GLC260 engine requires low-viscosity oil to enhance fuel efficiency, with SAE 0W-40 being the most suitable as it meets ACEA A3/B4 and MB 229.51 standards. The 0W indicates fast flow during cold starts, reducing engine wear, while the 40 ensures viscosity retention for protection at high temperatures. I recommend avoiding oils with excessively high viscosity, such as 10W-40, as they may affect oil pressure. Using certified brands like Castrol Edge 0W-40 can reduce engine carbon buildup and extend lifespan. Additionally, regular oil changes are essential to prevent impurity accumulation and ensure smooth driving—never overlook the recommendations in the maintenance manual.
