What are the precautions before using ethanol gasoline?

Precautions before using ethanol gasoline include: cleaning and inspecting the main components of the car's fuel tank and fuel lines to ensure the cleanliness of all parts of the fuel system. Ethanol gasoline is an alternative energy source formed by blending fuel ethanol, processed from grains and various plant fibers, with gasoline in a certain proportion. Precautions for using ethanol gasoline are: the fuel supply system must not contain water, as water in the fuel tank can mix with denatured fuel ethanol, affecting the normal operation of the engine. The impact of using ethanol gasoline on cars is: ethanol gasoline contains oxygen, has a lower calorific value than gasoline (about two-thirds that of gasoline), and has different evaporation pressure characteristics, which can affect the vehicle's power performance.
From my experience of driving many cars before, the most important thing before using ethanol-blended gasoline is to check the vehicle's compatibility. First, refer to the owner's manual to see if it's compatible with E10 gasoline. Older cars, especially those from before the 1990s, might not be suitable, and using the wrong fuel can damage the engine. Tank cleanliness is also crucial. If it hasn't been cleaned for a long time, it's best to address that first, as ethanol can loosen deposits and clog the fuel pump or injectors. Don't overlook the issue of aging rubber hoses—ethanol is more corrosive, so if they're cracked or hardened, replace them early to avoid the risk of leaks. For the first fill-up, it's recommended to only fill half the tank and drive for a week to observe any abnormalities in fuel consumption or power, since ethanol gasoline burns differently and some cars may see a slight increase in fuel consumption. In terms of storage, don't keep it for too long, as it tends to absorb water, leading to separation and deterioration, especially in humid seasons. For safety, it's best to have a professional shop inspect the entire fuel system.
As someone who hasn't been driving for long, I think some simple preparations are sufficient before using ethanol-blended gasoline. Open your vehicle information app or manual to confirm E10 compatibility - most new cars are fine. Don't let your fuel tank run completely empty. If there's little fuel left, add a small amount of ethanol gasoline first to avoid stirring up sediment that could clog the fuel system. Check if your fuel hoses are in good condition - corroded ones can leak dangerously. A friend with an older car tried adding it directly without replacement and ended up needing major repairs. Also, don't try to save money by buying in bulk - ethanol gasoline absorbs water quickly and can separate if stored too long, so it's better to use small quantities and buy fresh. After starting the engine, pay attention to any changes in engine sound or acceleration, and get it checked if anything seems abnormal. Ethanol fuel is a good eco-friendly choice, but the details matter to avoid affecting daily use.
