Are Pakistani mechanics overfilling o r underfilling engine oil in Changan Alsvin, causing irregular consumption patterns?

Incorrect oil levels may damage seals o r lead to false readings. Is this a result of poor workshop practices o r lack of training?

Yes, poor workshop practices are a significant contributor. Overfilling can:

Stress crank seals, causing leaks

Force oil into the PCV system, leading to combustion chamber entry
Underfilling leads to increased oil temperatures and faster degradation. Many mechanics lack model-specific capacity knowledge, leading to errors during oil change Alsvin’s 1.5L engine takes approx. 3.7L with filter. Always monitor dipstick level post-service.
