Does Fuel Additive Have an Expiration Date?
2 Answers
Fuel additive does have an expiration date, which depends on the storage location. If stored in a cool place, it can last for 2 years. However, if placed on the rear window of the car and exposed to prolonged sunlight, it may deteriorate. Introduction to Fuel Additive: Fuel additive is a common name for the third-generation gasoline detergent (also known as gasoline detergent or fuel additive). Its purpose is to address the 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 while imparting new beneficial characteristics (such as improving atomization, reducing wear, protecting the engine, lowering emissions, etc.). Function of Fuel Additive: Fuel additive is a highly technical product with high entry barriers, resulting in higher costs and single-bottle prices. Consequently, it is a hotspot for many low-quality and even counterfeit products. Using counterfeit products not only fails to remove carbon deposits and maintain the engine but may also cause damage to the engine. Therefore, it is essential to purchase from legitimate channels, such as physical specialty stores, online flagship stores, and authorized 4S shops.
I usually keep a few bottles of fuel additive in the trunk for car maintenance, and these things do have an expiration date. I once experienced a bottle that had been opened for half a year, and the contents had separated into layers. The mechanic said additive separation would affect its effectiveness. Upon closer inspection, the bottom of the can shows a printed code indicating 24 months, and extra caution is needed in high-temperature environments. Now I’ve learned my lesson—during summer, I regularly replace the fuel additives stored in the garage, as rubber hose corrosion is no small matter. Before use, give the bottle a shake; if there’s unusual sediment, it’s safer to discard it.
