What is the appropriate amount of fuel to keep in the tank during summer?

[DeGenevieve]

The specific amount to add depends on the driving distance. However, in high temperatures, gasoline stored in the fuel tank for too long can easily produce gum and sediment, which may clog the fuel injectors and cause the engine to operate abnormally. Below are specific methods for choosing engine oil for your car: 1. Performance selection: If you prioritize long-lasting performance, you can choose Mobil oil; if you focus on the cleaning properties of the oil for the engine, you can use Shell lubricants; for lubricants with strong oil film toughness, Castrol is recommended. 2. Driving conditions: If you frequently drive in congested areas, have an older vehicle, or operate heavy-duty vehicles for long-distance transport, the viscosity of the lubricant can be appropriately increased. 3. Engine type: Naturally aspirated engines can use mineral oil or semi-synthetic oil. 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 full synthetic oil.
