Proper engine maintenance can directly affect...

Correct answer

Fuel consumption.

Fuel consumption. Filters, fuel supply, lubrication and other engine systems affect operation and efficiency. Follow the manufacturer’s service intervals and procedures; proper maintenance helps avoid unnecessary fuel use but does not guarantee a fixed reduction. It does not by itself change the seating capacity or authorised masses recorded in the vehicle documents.
