How Much More Fuel-Efficient Are Diesel Cars Compared to Gasoline Cars of the Same Displacement?

[WestonMarie]

Diesel cars of the same displacement can save 30-50% more fuel compared to gasoline cars. Eliminate bad driving habits: Bad driving habits lead to higher fuel consumption. Habits such as prolonged idling, sudden acceleration and braking, shifting gears at excessively high or low RPMs, frequent speeding or driving too slowly are the main causes of increased fuel consumption. Avoid using low-quality gasoline: Long-term use of low-quality gasoline produces more impurities compared to normal-quality gasoline. This can more easily clog the fuel system, resulting in incorrect air-fuel ratios, overly rich fuel mixtures, and incomplete combustion before exhaust, leading to increased fuel consumption.
