Why is the JAC Jiayue X4 so fuel-consuming?
2 Answers
JAC Jiayue X4 has high fuel consumption for the following reasons: 1. Engine carbon deposits: Long-term operation of the vehicle inevitably leads to carbon deposits and sludge formation during gasoline combustion. If not cleaned promptly, these deposits will increase fuel consumption. 2. Spark plug failure: Damaged spark plugs reduce ignition energy, causing uneven combustion of the air-fuel mixture, resulting in slower acceleration and increased fuel consumption. Replace or clean carbon deposits from spark plugs. 3. Abnormal tire pressure: When tire pressure is too low or tread wear is severe, the contact area between tires and road surface increases, leading to greater friction, rolling resistance, and consequently higher fuel consumption. Check tire pressure and replenish promptly.
I've always felt that this car has high fuel consumption, mainly due to frequent city traffic jams and rapid acceleration, which cause the fuel consumption to skyrocket. Additionally, the JAC JY X4 has its own design issues. The 1.5T engine, while powerful, is not very efficient, consuming more fuel during low-speed city driving. Coupled with the heavy body weight, the fuel gauge drops sharply during acceleration. Personally, I recommend regularly checking tire pressure, as low pressure increases fuel consumption. Keep up with maintenance, such as replacing old spark plugs or dirty air filters, as they can degrade performance. Also, using the air conditioning in summer adds to fuel consumption. Changing driving habits, like maintaining a steady speed and braking less, may help. Using 95-octane gasoline might be slightly better, but overall, this car is more suited for highway cruising—city driving really consumes a lot of fuel.
