What happened to ZTE Hu Wei's engine? Because the fuel consumption was too high, there was no money to refuel.

There may be the following reasons: 1, the oil circuit is blocked; 2. The diesel pump should be cleaned or replaced; 3. The oil circuit is not well sealed somewhere; 4. The vent hole of the fuel tank cover is blocked; 5. The air filter is too dirty, so clean or replace it. 6. Air leaks somewhere in the intake pipe. Subsequent: 1. The oil circuit is not blocked. 2. The oil pump has been replaced. 3. Everything is fine. The fuel tank cover is still open. 5. The air filter element is not dirty. 6. There is no air leakage in the intake pipe, but you can afford to add oil by pressing the hand pump.
