There are many reasons for high fuel consumption. Besides the engine oil used, driving habits, road conditions, and carbon deposits in the engine all have an impact. I personally use imported GT engine oil and my fuel consumption is high. lower than before. At the same time, you should also correct your driving habits and check the carbon deposits in the engine, which will help reduce fuel consumption.

Since I haven't seen the actual car, I can only judge that there are several reasons for this phenomenon:
1. Battery failure or The generator is unable to produce electricity. If the battery fails, the generator may fail to produce electricity, resulting in power loss.Insufficient battery life.
2. Are the + and - terminals of the battery firmly connected? Get out of the car and check.
2. Has the line been changed? Or install an anti-theft system, modify the DVD system, one-button start system...? Check the source of the line.
3. The vehicle itself is locked against theft. Turn off the key, close the door, lock it again, wait a few minutes, then unlock and start the car. Try it and see if it works...
