What to Do If You Fill Up with the Wrong Fuel?
3 Answers
Here are the solutions for filling up with the wrong fuel: 1. If a high-octane gasoline vehicle is filled with low-octane gasoline, it is recommended that the owner drain the incorrect fuel or purchase relevant fuel additives to improve fuel quality and reduce engine damage caused by low-quality fuel. 2. If a low-octane gasoline vehicle is filled with high-octane gasoline, there is no major issue, but remember not to make the same mistake next time when refueling. 3. If a gasoline vehicle is filled with diesel or a diesel vehicle is filled with gasoline, contact a repair shop as soon as possible to clean the fuel tank and fuel system, and conduct a comprehensive inspection of the engine.
If I accidentally put the wrong fuel in my beloved car, such as adding diesel to a gasoline engine, I absolutely must not start the ignition! Quickly push the car to a safe area and immediately contact a repair shop for towing. Last time, I heard from an experienced driver that diesel in a gasoline engine can clog the fuel injectors, and in severe cases, it can directly ruin the engine. After towing it to the repair shop, the fuel tank needs to be completely drained and cleaned, the entire fuel system must be inspected, and the fuel filter should be replaced. The whole process can cost over a thousand yuan. If the engine has already been started, the repair costs can be even more frightening, reaching tens of thousands. But don’t panic too much—gas stations nowadays have surveillance, so remember to keep the receipts in case you can hold the gas station partially responsible.
I've done the wrong fuel thing before – painful lesson! As an auto mechanic, I know putting diesel in a gasoline car is the most dangerous because diesel's high viscosity can clog the precision components of a gasoline engine. In this case, you must shut off the engine immediately and call for professional assistance. During repairs, the fuel tank needs to be dismantled to drain the wrong fuel, and the entire fuel system must be flushed with specialized cleaning agents – even the high-pressure fuel pump needs disassembly for inspection. If you accidentally use lower-octane gasoline, short-distance driving may be fine, but prolonged use can cause engine knocking. Prevention is simple: take a photo of the fuel filler label before refueling, or stick a bright reminder note for yourself.
