Why are Sinopec gas stations cheaper?

[FernandoAnn]

Sinopec gas stations are cheaper because they entered the market late and have relatively low brand recognition, requiring them to reduce profit margins to gain market share. Additional information: Methods to distinguish gasoline quality are as follows: 1. Gasoline color: When refueling your car, pay attention to the color of the gasoline. Normally, gasoline should be water-white in color. If the color darkens, it may indicate that the gasoline has been stored for too long and has undergone chemical reactions. 2. Usage: Check if fuel consumption has increased. Inspect the exhaust pipe for sticky substances—if present, it suggests the gasoline is of poor quality. Also, observe if there are knocking issues during use or difficulties in ignition. 3. Smell: Gently waft the gasoline's odor. If there is a pungent or unusual smell, such as a smoky or sulfurous odor, it means the gasoline contains excessive sulfur or other impurities. 4. Touch: Dip your finger in the gasoline and rub it a few times. If the gasoline feels excessively greasy, similar to engine oil, it indicates poor quality. Alternatively, pour a small amount on your hand—if it evaporates quickly, the gasoline is of good quality.
