Generally, 5W-20 gray barrels or 5W-30 yellow barrels are used to synthesize engine oil. Self-priming engines do not require high oil levels, so mineral and semi-synthetic oils can be used. If you have a bigger budget, you can use full synthetic oil. In terms of viscosity selection, in winter, 5W lubricating oil can be used in most areas, while 0W lubricating oil is best used in northern areas. This lubricating oil has stronger low-temperature fluidity to adapt to driving environmental conditions.
Compared with self-priming, the turbocharged engine has a more compact engine structure and a harsher operating environment. They use higher grade lubes and require better lubes. It is best to use a fully synthetic oil. Choose a lubricating oil brand, pay attention to the long-term performance of the oil, choose Mobil oil; pay attention to the cleanliness of the oil, you can use Shell lubricating oil; if you need to use a strong oil film toughness, choose Castrol. For example, turbocharged engines are prone to carbon deposits at high speeds, so Shell oils with strong cleaning capabilities can be selected.
