Should T-equipped cars use 30 or 40 oil?
1 Answers
It depends on individual circumstances. Choose 40 for mineral oil, and 30 for synthetic or full synthetic oil. Here are the relevant details: Introduction: Cars with "T" refer to turbocharged engines. It is best to choose oil with slightly higher viscosity, such as 5W30, 0W40, or 5W40 engine oil. In addition to using the manufacturer's specified oil, full synthetic and semi-synthetic oils are also good choices. Turbocharging: The structure of turbocharging places higher demands on the engine, as its internal components must withstand high temperatures and greater impacts, compression, and other working conditions. When selecting oil for turbocharged cars, it must have excellent anti-wear properties and be heat-resistant. Full synthetic or semi-synthetic oils can precisely meet these requirements. The turbocharger is one of the most vulnerable components in a turbocharged engine. According to relevant data, over 80% of turbocharger failures are due to insufficient lubrication from the oil. Full synthetic oil is currently the most suitable choice for turbocharged engines.
