Should Gasoline Engine Cleaner Be Added Before or After Refueling?
2 Answers
It can be added either before or after refueling. Gasoline engine cleaner is designed to compensate for the quality issues inherent in fuel and the limitations in automotive mechanical manufacturing, thereby helping the gasoline engine overcome cold-start effects and crevice effects, and remove carbon deposits from intake valves and fuel injectors. Below are detailed explanations about it: 1. Introduction One: The main component of the cleaner is polyisobutene amine, which has a chemical structure similar to detergents, with one end being a polar group and the other end a non-polar group. 2. Introduction Two: The non-polar group ensures the product's solubility in fuel, while the polar group can adhere to the surface of carbon deposits or metal parts, serving to remove carbon deposits and prevent their formation, commonly referred to as the cleaning and maintenance functions.
I've always liked adding gasoline engine cleaner before refueling. This is my routine: first open the fuel tank cap, pour in the cleaner, then add gasoline. The reason is simple - when fresh gasoline rushes into the tank, it vigorously stirs the cleaner, allowing it to mix evenly with the fuel and cover areas like fuel injectors and intake valves, effectively dissolving carbon deposits and impurities. Conversely, if added after refueling, the cleaner might settle at the bottom or float on top, resulting in uneven mixing and significantly reduced effectiveness. I add it every 5,000 kilometers or so, choosing reputable brands. The engine runs smoother and quieter, with slight fuel efficiency improvements. This little trick helps maintain my car in good condition, preventing common issues while saving money and hassle. Sticking to it has proven particularly practical.
