Do poorly maintained air filters, spark plugs, o r injectors contribute to decreased fuel economy in Changan Karvaan across Pakistan?

Dusty environments and delayed maintenance can lead to clogged filters and inefficient combustion. Are owners neglecting basic service schedules?

✅ Very common cause.

Dusty roads in Pakistan clog air filters quickly within 4,000–5,000 km.

Worn spark plugs = poor combustion = more fuel burned

Dirty injectors = lean o r rich mixture issues

➡️ Owners often delay basic maintenance, directly affecting fuel consumption.
