Can a gasoline indicator be changed to an electric one?

[DelVictoria]

The nature of the indicator cannot be changed. Here is the relevant introduction about gasoline grades: 1. Different grades of gasoline have different densities: The most commonly encountered are 92 and 95 grades. The density of 92 gasoline is approximately 0.72g/ml, 95 gasoline is about 0.725g/ml, and 98 gasoline is about 0.737g/ml. This shows that the higher the gasoline grade, the greater its density, primarily because gasoline is a mixture, and different grades are formulated by adding various additives to the base gasoline. 2. Grades: Higher-grade gasoline uses more additives, and the density of these additives is greater than that of the base gasoline. Therefore, the higher the gasoline grade, the greater its density. It is worth mentioning that the reason gasoline has different grades is mainly due to their different anti-knock properties, not that higher grades have fewer impurities. The higher the gasoline grade, the better its anti-knock performance, making it less likely for the engine to experience premature combustion during operation. Additionally, the engine's compression ratio determines the gasoline grade.
