What if JAC t8 can't afford to refuel at the speed limit?

Check the high voltage line, clutch and heat dissipation. According to the public information query, the reasons why JAC t8 can't afford to refuel at the speed limit are as follows:

1, wrong oil use or heat dissipation problem.

2. Did the car clean the accelerator, fuel injector and three-way catalytic converter? So we can check whether the high-voltage line works normally, check whether the clutch slips and check whether there is a problem with heat dissipation.
