Why is the fuel consumption of the classic Mazda3 so high?

[McRhett]

Classic Mazda3's high fuel consumption may be due to excessive carbon deposits in areas such as the throttle body, idle motor, intake valves, intake manifold, combustion chamber, spark plugs, and fuel injectors. Relevant information about the Mazda3 is as follows: 1. Exterior: Inheriting the tone of the Mazda6, the Mazda3 features a low-sloping chrome five-point grille, extending into three sharp lines on the hood; the three-tube blackened eagle-eye headlights give the new Mazda3 a modern and avant-garde first impression. The elongated wheelbase, the high-back short rear suspension design formed by the low front and high rear waistline, and the clean lines drawn by the inverted L-shaped C-pillar constitute the main visual focus of the Mazda3's sports car style, not only presenting the visual proportion of a coupe but also the concise and powerful beauty of a hatchback. The precise gap between body panels, combined with flared wheel arches, the factory rear spoiler, stainless steel dual exhaust pipes, and 16-inch aluminum alloy wheels, gives an overall impression of a solid outline design that blends refinement and sportiness. 2. Interior: The classic version of the Mazda3 shows little change from the older models. It maintains the original layout and continues the sporty and fashionable overall style of the previous models, with the most noticeable change being the piano black finish on the audio panel of the center console, making it more refined and aesthetically pleasing. Additionally, carbon fiber decorative strips have been added to the doors and center console, creating a strong sense of sportiness. The changes in the 1.6-liter model are even smaller and hard to notice without close observation, limited to the piano black decorative strips and changes in fabric materials.
