Is Castrol Edge a Low-Ash Engine Oil?
1 Answers
Castrol Edge is a fully synthetic engine oil. Below are specific methods for selecting engine oil for cars: 1. Performance selection: If you prioritize long-lasting performance of the oil, you can choose Mobil engine oil; if you focus on the oil's cleaning effect on the engine, you can use Shell lubricants; if you need lubricants with strong oil film toughness, Castrol is recommended. 2. Driving conditions: For frequent driving in congested areas, older vehicles, or long-distance heavy-load transportation, the viscosity of the lubricant can be appropriately increased. 3. Engine type: For naturally aspirated engines, mineral oil and semi-synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-grade lubricants with better fluidity, preferably fully synthetic oil.
