Adding fuel additive to your car is beneficial as it helps resolve carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restoring the engine to optimal performance. With continuous use, it can eliminate carbon buildup troubles in the fuel injectors, intake valves, and intake manifolds of the fuel system. Below is relevant information about fuel additives: 1. The main component of fuel additives is high-molecular-weight ashless surfactants, which dissolve in automotive fuel and can break down, detach, and disperse carbon deposits accumulated on metal surfaces. These are then encapsulated into carbon particle micelles and enter the combustion chamber along with the fresh air-fuel mixture for combustion. Some non-combustible carbon deposits are expelled through the vehicle's exhaust. 2. Utilizing nano-molecular materials, gasoline additives directly attack the long-chain carbon bonds in fuel molecules, creating "micro-explosions" in the combustion chamber. This results in secondary atomization of gasoline, promoting complete combustion, enhancing thermal efficiency, and reducing fuel consumption.

As for fuel additives, it depends on the specific situation. My old car has been running for eight years, and during every maintenance check, the mechanic would point out severe carbon buildup on the intake valves. Later, on a friend's recommendation, I started using fuel additives. After consistently using them for three full tanks of gas, I did notice the throttle felt more responsive, and the idle vibration reduced. However, it's crucial to buy reputable brands containing PEA (Polyether Amine) ingredients, as off-brand products might damage the fuel injectors. New cars don't need them at all—the maintenance manual doesn't require it. Most importantly, don’t expect instant results; it takes about three to four consecutive bottles to see noticeable effects. Think of it as giving your engine a deep cleanse.

Do China VI diesel vehicles still require urea solution?

China VI vehicles still require urea solution, but the standards are more stringent. The primary function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water. Using urea solution can reduce fuel consumption, increase power, and promote energy efficiency and environmental protection, which is why the government has mandated the implementation of China V and China VI policies. Below is relevant information about urea solution: 1. The technical name for automotive urea is Diesel Exhaust Fluid (DEF). It is commonly used in diesel engines as part of the SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition consists of 32.5% high-purity urea and 67.5% deionized water, aimed at reducing nitrogen oxide pollutants emitted by diesel engines. 2. Failure to use DEF, or using DEF of insufficient purity or inferior quality, will result in automatic engine deceleration. Additionally, inferior-quality DEF can contaminate the catalyst in the SCR catalytic reaction tank, leading to severe consequences.

Will Replacing Spark Plugs Reduce Fuel Consumption?

Replacing spark plugs can reduce fuel consumption. If spark plugs are damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and decreased power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of spark plugs, including scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plugs are damaged and should be replaced. Location of Spark Plugs: Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. Generally, platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

Where is the air filter of FAW-Volkswagen Bora located?

Volkswagen Bora's air filter is located inside the glove compartment on the passenger side. Open the engine hood, remove the four screws on the baffle, and lift the baffle to see the air filter of the Volkswagen Bora. Here is some relevant information: 1. Generally speaking, how often the car's air filter needs to be replaced depends on the usage conditions. For ordinary urban family cars, it is usually replaced every six months or once a year. If the road conditions are dusty, more dust will enter the car, causing the air conditioning system to become very dirty. Additionally, some users prefer to park under trees or temporarily stop near trees, where tree fruits may fall on the air filter's intake, also making the air filter very dirty and requiring early replacement. Moreover, the frequency of air conditioning use varies in different seasons, which can also have some impact. 2. The Volkswagen Bora is the first independently designed model by FAW-Volkswagen and is hailed as a new car that "inherits the classics and surpasses the classics."

What is the fuel tank capacity of a Polo in liters?

The fuel tank capacity of the Volkswagen Polo is 42.5 liters, as officially announced. Owners who have purchased a Volkswagen Polo can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the Volkswagen Polo is 92 octane, with a fuel consumption of 5.5 liters per 100 kilometers. A full tank of fuel allows for a driving range of approximately 772 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately displayed on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, leaving some space between the safe fill level and the tank opening. This space accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening, the actual refueling volume may exceed the marked tank capacity.
