What direct effect does proper engine maintenance have on the vehicle?

Question

DentroTest · Accepted Answer

Carrying out regular and proper maintenance on the engine directly and decisively influences fuel consumption. Elements such as clean air and fuel filters, calibrated spark plugs or injectors and the right oil level and type allow combustion to be complete and efficient, avoiding loss of power and unnecessary fuel costs. By contrast, rolling resistance and the working temperature of the tires depend on factors unrelated to the engine, such as inflation pressure, the condition of the tread, the load of the vehicle and friction with the road surface.
