Why are some Changan Alsvin owners in Pakistan reporting excessive engine oil consumption even under normal driving conditions?

Several users claim their Alsvin requires oil top-ups between scheduled oil changes. Is this an engine design issue o r due to quality control problems?

Yes, multiple Alsvin owners have reported needing oil top-ups before reaching the scheduled service interval typically every 5,000–7,500 km. The root causes appear to be a combination of:

Loose engine tolerances o r quality control issues during manufacturing

Poor piston ring seating in some units, leading to oil slipping into the combustion chamber

Valve seal wear after relatively low mileage
While not affecting every unit, this issue has surfaced frequently enough to indicate non-isolated engine design o r assembly concerns.
