Does suddenly switching to ethanol gasoline affect the car?
2 Answers
Suddenly switching to ethanol gasoline can affect the car. Precautions for switching to ethanol gasoline are as follows: 1. Clean the vehicle's interior before use: The ethanol in ethanol gasoline has strong dissolving and cleaning properties. When using ethanol gasoline for the first time, especially after one or two tanks, the ethanol will soften and dissolve various impurities deposited in the fuel tank and fuel lines, such as rust, mixing them into the fuel, which may cause fuel line blockages. 2. Prevent excessive moisture in the engine: Ethanol gasoline contains a certain amount of denatured fuel ethanol, which is hydrophilic and easily mixes with water, unlike gasoline, which can separate from water, allowing water to settle at the bottom of the fuel tank. Therefore, when using ethanol gasoline for the first time, the fuel tank should be inspected to prevent the ethanol gasoline from mixing with any accumulated water at the bottom of the tank, which could lead to excessive moisture in the fuel and affect the engine's normal operation.
I've driven cars from different eras, both new and old, and the sudden switch to ethanol-blended gasoline really depends on the specific model. Many modern cars are designed with mixed fuels in mind, such as E10 gasoline with 10% ethanol, and they run smoothly with stable performance. However, older cars, like my decade-old model, showed noticeable hesitation during startup and an increase in fuel consumption by half a liter after filling up. An inspection revealed that the ethanol had dissolved sludge in the fuel tank, clogging the filter, and also caused slight corrosion to the rubber seals. Over time, the car adapts, but before making the switch, it's best to check the manual or consult the manufacturer's advice to avoid being stranded on the road. Overall, it's not a dangerous move, but caution is always wise.
