How to Identify Fake 95 Octane Gasoline?
1 Answers
Methods to identify fake 95 octane gasoline are as follows: 1. Water adulteration in gasoline: "Water-adulterated gasoline" refers to gasoline with water content exceeding national standards. According to industry standards for gas stations, the water level in fuel tanks should not exceed 5mm. Since gasoline and water are immiscible, this doesn't normally affect engine combustion. However, some unscrupulous merchants physically or chemically blend water into high-grade gasoline to reap excessive profits. While such micro-emulsified gasoline won't cause immediate severe damage to engines or fuel systems, prolonged use of inferior products will accelerate wear on fuel pumps, filters, injectors, and even the engine itself. Impurities may clog fuel lines, preventing vehicle startup, while excessive water separation can corrode metal components (like pump bearings). Genuine gasoline appears light yellow, clear and transparent with a strong but not pungent odor, whereas watered-down gasoline has weaker smell and overly pale color. 2. Excessive gum content: Gasoline with high gum content appears darker, orange-red in color. Known as "dirty fuel," it easily causes fuel filter/injector clogging and poor atomization. Long-term use promotes carbon deposits on valves and combustion chambers, impairing engine performance. Qualified unleaded gasoline should be light yellow or pale red - deep red and cloudy appearance indicates inferior quality. Similarly, standard diesel should be transparent amber; darker shades suggest quality issues. 3. Gasoline with excessive mechanical impurities: These refer to all insoluble particulate matter (sand, clay, iron filings, etc.) suspended in fuel. Contaminated gasoline appears murky. Consumers can perform a simple test by dropping fuel onto A4 paper - genuine gasoline spreads evenly in circular patterns with transparent coloring and non-irritating odor. Inferior fuel leaves black/dark yellow residues at edges with visible particles and typically emits strong pungent smells.
