What kind of engine oil does Volvo use?

[DelPaisley]

Volvo's original engine oil brand is Castrol. The explanation of engine oil specifications and the selection of engine oil are as follows: Explanation of engine oil specifications: Engine oil is the lubricant used by the engine, composed of base oil and additives. The 'W' in the oil specification stands for winter. The smaller the number before 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable temperature. The larger the number after 'W', the higher the viscosity and the higher the applicable temperature. Selection of engine oil: Naturally aspirated engines have lower requirements for oil performance and can use mineral oil and semi-synthetic oil, while those with a higher budget can use fully synthetic oil. Compared to naturally aspirated engines, turbocharged engines have a more precise structure, operate in more complex environments, and have higher requirements for oil quality, requiring lubricants with better fluidity. It is best to use fully synthetic oil. Engine types: For naturally aspirated engines, mineral oil and semi-synthetic oil can be chosen. Compared to naturally aspirated engines, turbocharged engines have a tighter structure, operate in harsher environments, require higher-grade lubricants, and need lubricants with better fluidity. Fully synthetic oil is the best choice.

I've been driving a Volvo for seven or eight years and have gained quite some experience in choosing engine oil. Current models basically require low-viscosity 0W-20 oil, which must meet Volvo's own VCC RBS0-2AE certification standard. This certification is particularly important as it relates to the oil's high-temperature cleaning performance and oxidation resistance. I once used oil without this certification, and the engine noise became noticeably louder. It only returned to normal after I switched back to the original oil at the dealership. Actually, brands like Castrol Edge with Volvo certification can be used, but the key is not to arbitrarily change the viscosity. Older models might require 5W-30 oil, so it's best to check the maintenance manual. Temperature is also a factor—for example, in northern winters, you should choose a type with good low-temperature fluidity. There's a label on the oil cap, so remember to check it before changing the oil. Using the wrong type could affect the engine's lifespan.
