4.7 Reasons for High Fuel Consumption of Grand Cherokee

The oil label is not suitable. For example, the misuse of high viscosity engine oil will increase the mutual resistance between engine parts and increase fuel consumption. Increase the vehicle load. Especially the trunk, some car owners have become warehouses for the convenience of the trunk. It should be noted that every time a car increases its weight, its fuel consumption will increase by one point. Step on the gas in the air. This cool behavior will become the backbone of the increase in fuel consumption for a long time.

Other reasons for high fuel consumption

Always change lanes when driving. Car owners who are unfamiliar with the road or "reckless" driving should pay more attention. Changing lanes means speeding up, so they have to refuel fiercely, which naturally costs oil.

Air conditioning is often turned on in the car. Especially when idling, turning on the air conditioner undoubtedly increases the load of the engine, which not only affects the fuel consumption, but also may cause insufficient power sometimes.

Fuel consumption is related to many factors. If the road conditions and driving habits are the same, check whether the spark plug gap is too large and whether too much carbon deposits lead to poor ignition, which will increase fuel consumption. The spark plug needs to be replaced to see if the oil nozzle leaks oil.

Replace the fuel injector, too much carbon deposit in the valve will also lead to an increase in fuel consumption. Clean the throttle and engine carbon deposit, and check the performance of relevant sensors, such as oxygen sensor, water temperature sensor, air temperature sensor, throttle position sensor and air flow meter inlet pressure sensor.
