What kind of engine oil should be used for Mercedes-Benz GLA?
1 Answers
Mercedes-Benz GLA requires engine oil with a High Temperature High Shear (HTHS) value above 3.5 (both GT's 0W30 and 0W40 exceed 3.5) to prevent lubrication performance degradation under high-speed and high-temperature conditions, which could lead to power loss and sluggish acceleration at high RPMs. Engine oil selection: Naturally aspirated engines have relatively general requirements for oil quality and can use mineral oil or semi-synthetic oil. If the owner has a higher budget, fully synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-performance oil with better fluidity. Fully synthetic oil is recommended. Brand selection: For lubricant brand selection, if long oil life is a priority, Mobil lubricants can be chosen; if engine cleaning capability is important, Shell oil is recommended; for lubricants with strong oil film resilience, Castrol can be selected. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning capabilities can be chosen.
