Does Mercedes-Benz Need Fuel Additives?

Mercedes-Benz can use fuel additives. Functions of fuel additives: In addition to removing carbon deposits, fuel additives can also inhibit the formation of carbon deposits. Cleaning-type fuel additives can adhere to metal surfaces, forming a protective film to reduce carbon deposit formation. Therefore, the primary purpose for new cars is prevention, typically used after 1,000 kilometers. Choosing fuel additives: High-quality fuel additives can positively impact carbon deposits, fuel consumption, emissions (power and acceleration), while inferior ones can be harmful. Therefore, it is crucial to choose fuel additives carefully and avoid low-quality products, as they may have adverse effects.

What is the reason for the Nissan Sunny's brake being hard to press?

Nissan Sunny's brake being hard to press is due to: failure of the vacuum booster pump, issues with the brake booster pump. Vacuum booster pump failure: If the car's vacuum booster pump leaks or fails, the force applied to the brake pedal is amplified by the brake booster pump. If the vacuum booster pump fails, the brake loses its power assist, making it very hard to press. Brake booster pump: Pressing the brake after the engine is turned off is also related to the brake booster pump. The brake booster pump continuously generates vacuum only when the engine is running. When the engine is off, it relies on the remaining vacuum assist, which will be restored after starting the engine, and is not a malfunction.

What does the foot brake of the new Sylphy mean?

The foot brake of the new Sylphy works on the same principle as the handbrake, but instead of being pulled by hand, it is operated by foot. The foot brake is located to the left of the brake pedal, saving space in the central console area, which makes the interior look more aesthetically pleasing. Using the foot brake requires less effort than the handbrake, but novice drivers may accidentally press it. Additionally, for drifting enthusiasts, the foot brake is less effective compared to the direct action of a handbrake. The new Sylphy is a family sedan under Dongfeng Nissan. In terms of exterior design, the enlarged grille gives the car a more imposing look, while the continuous waistline running from front to rear enhances the vehicle's dynamic appearance. It maintains a smooth, rounded style while presenting a more robust and graceful silhouette, with overall styling that leans towards a youthful appeal.

What brand are the original tires on the Buick Verano?

The original tires on the Buick Verano are the Goodyear EfficientGrip series, with a tire size of 205/55R16. The Goodyear Tire & Rubber Company was founded in 1898 and has a history of over a hundred years. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products in over 90 factories across 28 countries. For the Buick Verano's tires in daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves on the tires gradually become shallower. If the tread wears out, it will lose its drainage and anti-skid functions, significantly reducing the car's performance. Small cracks may seem minor but can be a hidden danger for blowouts at high speeds. Additionally, promptly remove pebbles stuck in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials that may cause rubber deterioration. After parking, the driver should avoid turning the steering wheel, as this action accelerates tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure may increase. In such cases, park to let the tires cool down. Avoid deflating to reduce pressure or splashing water to cool them, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear due to dragging between the tires and the ground.
