Fengshen a60 is generally the most prone to problems.

1. There are problems in the oil circuit system, such as nozzle blockage, oil leakage in the oil pipe, and the aging power of the oil pump tends to decline after long-term use. Insufficient oil supply pressure in the oil system will also cause the vehicle to be unable to refuel.

2. Oil problem. Using inferior and unqualified engine oil or gasoline is easy to damage vehicle parts, such as oil pump, nozzle, oil pump, etc. Inferior gasoline has poor fuel efficiency and high oil consumption, while inferior engine oil has poor lubrication effect, high viscosity and is easy to deteriorate.

3, carbon deposition, common is throttle carbon deposition, spark plug carbon deposition. Too much carbon deposit is easy to drive and deflagrate, which is a force against engine power. Moderate deflagration can improve engine power, but this force is generally uncontrollable, which often hinders engine work and reduces engine power.

4. The air intake and exhaust system is blocked, for example, the air filter is too dirty and the three-way catalytic device is blocked, which will affect the engine breathing, so poor breathing will eventually lead to the engine not being able to refuel when climbing.
