Three Critical Points of Automotive Maintenance Are Being Ignored by Drivers and Resulting in Costly Damages, Accelerated Wear and Serious Failures in Vehicle Systems

The routine of caring for a car usually includes basic checks, but three important procedures continue to be ignored by many drivers. This list of maintenance is essential within any automotive maintenance routine, as it involves items that directly influence the operation and durability of key vehicle components.

Replacement of Hydraulic Steering Oil

The first maintenance often forgotten is the replacement of hydraulic steering oil. Many owners fail to even check the system’s level, which depends on this fluid to preserve its protective properties.

With continuous use, the oil degrades and loses efficiency, causing wear on the assembly and making the steering heavier.

Replacement of Automatic Transmission Oil

The second critical point involves changing the automatic transmission oil. Many drivers follow only the owner’s manual recommendation and are unaware of what defines severe use, which leads to incorrect change intervals. This oversight promotes the formation of sludge, reduces lubricant oil pressure, and impairs overall assembly function.

If the fluid is not changed at the correct frequency, the transmission begins to show progressive failures. Therefore, choosing a high-performance lubricant becomes essential to maintain performance and extend the system’s lifespan. This care reinforces the importance of understanding the real demands of automotive maintenance in vehicles with automatic transmissions.

Review of Differential or Transfer Case

The third forgotten item is the replacement of oil in the differential or transfer case, especially in all-wheel drive SUVs.

Many owners do not perform this replacement and end up facing losses exceeding R$ 10,000 due to a lack of proper lubrication. The fluid is responsible for reducing friction and protecting gears working under high loads.

To avoid damage, it is recommended to check for possible leaks and confirm the oil level at each maintenance. This practice ensures the proper functioning of the drivetrain and prevents severe wear that could easily be avoided.

Final Guidelines

Drivers are encouraged to send questions to receive guidance and clarify issues related to care that may go unnoticed.

Understanding each stage of automotive maintenance helps identify failures before they become costly problems, preserving vehicle performance and reducing the risk of serious damage.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Great Atlantic Sargassum Belt has ceased to be a climatic phenomenon and has become a biological system that feeds on itself, with 8,000 kilometers in length, 37 million tons of algae, and scientists confirm that it is now permanent.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Engineers had to pour concrete mixed with tons of ice throughout entire nights in the Dubai desert to erect the Burj Khalifa; any carelessness could clog the pipes half a mile high.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

Turkey hit a target using a real warhead and confirmed that its SOM-J cruise missile is ready, another step for the country to become a power that manufactures and exports its own military technology.

While the United States and China compete over giant rockets and lunar bases, India made a “spaceplane” land on its own at over 320 km/h after being released by a helicopter at an altitude of 4.5 km; Pushpak shows that New Delhi also wants to enter the era of reusable space vehicles.

Japan and Mercosur may reach an agreement to lower the cost of cars and auto parts, with manufacturers like Toyota, Honda, and Nissan coming into focus.

Volkswagen is preparing an SUV derived from the new Amarok to compete with the Toyota SW4 and Haval H9, utilize the Argentine Pacheco factory, and transform a pickup into a more profitable family of products.

Virginia engineers transform 100,000 tons of demolished concrete from the Hampton Roads bridge into artificial reefs in the Chesapeake Bay, turning the debris from a mega-construction project into marine shelter while the old structure was still being dismantled.
