Yes — crucially.
Delayed maintenance leads to:

Thicker, degraded oil increasing drag

Clogged air and fuel filters

Carbon buildup in injectors and valves

Skipping scheduled oil changes o r using low-quality engine oil can fuel economy by 15–20%. Unfortunately, many Kalam owners cut corners on servicing due to cost o r limited parts availability.
