Why is the fuel consumption of the Leiling Hybrid increasing?

[AlyssaFitz]

Hybrid models ultimately still rely on an engine, strictly speaking, they are still fuel-powered vehicles. Therefore, fuel consumption in winter will increase just like in conventional fuel vehicles. There are two main reasons for the increased fuel consumption: heating demand and engine warm-up. High fuel consumption in the Leiling Hybrid is generally caused by the following situations: fuel consumption and driving conditions: fuel consumption is related to many factors such as driving conditions, driving habits, vehicle maintenance conditions, and vehicle load; large mileage gap: a significant mileage gap is also an issue, as there are too many factors affecting fuel consumption; driving habits: such as driving habits (sudden acceleration, sudden braking, coasting in neutral, speed and gear mismatch), low tire pressure, poor-quality engine oil, ignition system failure, and electrical control system failure, all of which can increase the vehicle's fuel consumption.

I've been driving a Levin Hybrid for five years, and recently noticed an increase in fuel consumption. Here are some common reasons: when the weather gets colder, the engine starts more frequently to warm up, and the hybrid system automatically burns more fuel to maintain temperature. It's normal for winter fuel consumption to be 1-2 liters higher than in summer. If you've been making lots of short trips recently where the battery doesn't have time to fully charge before the engine starts, fuel consumption will be even higher. Low tire pressure is particularly fuel-intensive - last time my tire pressure dropped to 2.0, it added 0.8 liters per 100 km, so remember to check tire pressure monthly. Another factor is battery aging, especially after four or five years - as the small battery's charging capacity declines, the engine will start more frequently to compensate. Finally, examine your driving habits: sudden acceleration and braking can make power transitions less smooth, and pressing the accelerator past one-third will forcibly start the engine.

Last year, my hybrid suddenly experienced a surge in fuel consumption. After some troubleshooting, I discovered several key issues: during maintenance, the engine oil was overfilled by half a liter, increasing the engine's operating resistance—removing the excess immediately improved fuel efficiency. The air filter hadn't been replaced in two years, and dust clogged the intake, reducing the engine's combustion efficiency. The spark plugs were heavily carbon-fouled, causing delayed ignition and rough hybrid transitions. Using cheap fuel for a long time left impurities that affected the fuel injectors. Once, a brake caliper was slightly stuck, heating the wheel hub and wasting fuel. And don’t forget the trunk—I left half a case of bottled water in there permanently, adding the equivalent of a child’s weight. I recommend a thorough maintenance service; addressing these issues should restore normal fuel consumption.

Driving style has the greatest impact on hybrid fuel consumption: I went through a phase of being addicted to racing, always flooring the accelerator, which caused my fuel consumption to rise from 4.8L to 6.2L. The hybrid system is most fuel-efficient in normal mode, as sport mode forces the engine to start. Avoid tailgating in traffic jams, as repeatedly braking wastes kinetic energy by converting it into heat on the brake pads. Air conditioning temperature settings are also crucial—each degree lower increases power consumption by 3%. Once, I drove with the sunroof slightly open, increasing the drag coefficient and adding 0.5L to my fuel consumption. Before carrying heavy luggage, check the gradient on a map; preserving enough battery before a long uphill climb can save a lot of fuel. Try gentle driving for a week—the results might surprise you.
