Should Fuel Additive Be Added Before or After Refueling?
2 Answers
Fuel additive should be added before refueling. Fuel additive is essentially a type of gasoline additive. Most gasoline additives on the market are designed to clean carbon deposits, while some are used to unclog fuel lines. If it's a branded gasoline additive, it can indeed remove carbon deposits and prevent their formation. Fuel additive (also known as gasoline detergent or fuel additive) is a type of automotive chemical and a common name for the third generation of gasoline detergents. Its purpose is to address carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the engine to optimal performance, and compensate for certain deficiencies in gasoline properties, endowing gasoline with new beneficial characteristics such as improved atomization, reduced wear, engine protection, and lower emissions.
As a veteran driver with over 20 years of experience, I always make it a habit to add fuel additive before refueling. This is because fuel additives need to fully mix with gasoline to effectively clean the engine. Adding it to the fuel tank before pumping gas allows the turbulence during refueling to naturally stir and mix the additive, reducing sediment buildup. If added after refueling, uneven mixing may lead to localized high concentrations, diminishing its effectiveness. I remember one time when I added it after refueling, the engine noise actually increased. After researching, I learned that poor mixing can damage components. Now, I use it once per oil change cycle, prioritizing well-known brands to avoid impurities. Since sticking to this routine, my car's fuel consumption has noticeably decreased. I recommend everyone develop the habit of adding fuel additive before refueling – it takes just an extra second but protects your beloved vehicle and extends its lifespan.
