New cars do not require fuel additives; since the effects of fuel additives are relatively limited, and the fuel at domestic gas stations already contains fuel additive components, coupled with the fact that new car engines have short service lives and good working conditions, they basically do not produce carbon deposits. Therefore, there is no need to add fuel additives to a new car. Additional information: 1. The role of fuel additives: Fuel additives, also known as fuel enhancers, primarily function to clean carbon deposits, which has always been their main selling point. Additionally, they help maintain the engine and fuel system. Some special-purpose fuel additives can also improve the anti-knock properties of fuel. 2. Composition of fuel additives: Fuel additives are mainly composed of more than ten components, including nano-molecules, cleaning active factors, antioxidants, anti-corrosion agents, and demulsifiers. They are designed to target harmful components in fuel such as sulfur, gum substances, and engine carbon deposits, thereby achieving effects like enhancing power, promoting combustion, anti-oxidation, anti-wear, cleaning, dispersion, demulsification, anti-corrosion, and lubrication.

As a car enthusiast who has driven several vehicles, I believe there's absolutely no need to add fuel additives to new cars. New car engines come with finely tuned factory settings, and their fuel systems are spotlessly clean. Adding those additives is not only a waste of money but could also interfere with the electronic control systems, even triggering warning lights. Modern car engines are highly efficient, with carbon buildup being negligible. I suggest ignoring the advertising hype – for new cars, focus on proper break-in driving habits like gentle throttle application and smooth acceleration. Only consider additives after tens of thousands of miles if truly necessary. Developing the habit of choosing quality gas stations is far more practical than adding unnecessary products. The money saved could be better spent on regular maintenance like oil changes or air filter cleaning, which will extend your vehicle's lifespan.

I'm quite good at budgeting. After driving for many years, I found that using fuel additives is a complete waste. When the car is new, the engine performs perfectly fine. A bottle of fuel additive costs over ten yuan, and using it a few times adds up to hundreds, yet the effects are neither visible nor tangible. After trying it myself several times, I didn't see any reduction in fuel consumption or improvement in performance—just wasted money. It's better to save that money for essential maintenance, like using higher-quality engine oil or checking the tires. The cost of maintaining a new car is already high enough; why add extra expenses? Take those ads claiming to clean the system with a grain of salt—the reality is that new cars don't need it at all. Focus more on driving habits, like avoiding sudden braking, for long-term peace of mind and savings.

How much power can be gained by flashing a Stage 1 tune on a Civic?

Flashing a Stage 1 tune on a Civic typically increases power output by around 210 horsepower. The exact parameters vary depending on the horsepower tuning method, with some reaching 220 horsepower, others 235 horsepower, and even some achieving a more significant boost up to 245 horsepower. The principle of flashing a Stage 1 tune: Flashing a Stage 1 tune primarily involves adjusting the ECU parameters of the vehicle to enhance its power. It's worth noting that this method does not involve modifying the vehicle's hardware. The Stage 1 tune mainly adjusts the engine's fuel injection quantity or ignition timing advance angle, while also requiring adjustments to the engine's air intake volume. This allows the vehicle's latent power performance to be fully utilized. The impact of flashing a Stage 1 tune: It's important to mention that the CVT transmission equipped in the Civic has a limited torque capacity. If the horsepower increase from the Stage 1 tune is too high, it can significantly affect the transmission's performance. After flashing the Stage 1 tune, the vehicle's requirement for fuel quality increases. If the engine previously used 92-octane gasoline, it will now require 95-octane gasoline. This is because the engine's overclocked operation demands higher-quality fuel. Additionally, the engine's temperature requirements become more stringent, necessitating a better cooling system to support the overclocked operation. Otherwise, it could negatively impact the engine's lifespan.

What Causes the Airbag Light to Illuminate on the Car Dashboard?

Reasons for the airbag light illuminating on the car dashboard: 1. Dashboard self-check. Within a short period after entering the car and starting the ignition, the dashboard performs an automatic check. The airbag light will automatically turn off after the check is completed, which usually takes about 5 seconds. This is a normal phenomenon. 2. False fault. If the battery is low on power, it may also cause the airbag light to illuminate. 3. Actual fault. If the above two reasons are ruled out, it may be due to a circuit malfunction, and the car should be repaired promptly. The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, the airbag can reduce head injuries by 25% and facial injuries by approximately 80%.

Can Subaru Replace Piston Rings?

Subaru can replace piston rings. Reasons for replacing piston rings: Practice has shown that the wear and failure rate of piston rings is much faster than the rate at which cylinder wear reaches its limit. Therefore, often between two major engine overhauls or during maintenance, since the cylinder liner wear is relatively light and does not require cylinder honing or replacement, the engine's performance can be improved by replacing the piston rings. Precautions for replacing piston rings: Check and adjust the ring end gap, side clearance, elasticity, and leakage rate. Select piston rings that match the repair dimensions of the cylinder and piston. Alternatively, the old top compression ring on the piston can be moved to the first ring groove, and the newly selected rings can be installed in the lower ring grooves. This can prevent poor sealing between the new rings and the cylinder wall, which could lead to gas leakage and oil consumption. Correct the wear ridge at the top of the cylinder. A scraper can be used for this correction. When scraping, start from the inside and scrape outward to avoid damaging the cylinder wall surface. Metal shavings from scraping should be properly handled and must not be allowed to fall into the crankcase. If the wear ridge is not corrected, the new rings will impact the ridge during operation, causing the rings to crack or the ring lands to break, potentially leading to cylinder scoring. The end gap of the new rings should be filed to the correct size based on the cylinder position when the piston is at bottom dead center. Special attention should be paid: do not use the maximum wear point at the cylinder's upper wear ridge as the basis for determining the end gap of the rings.

What is the oil viscosity of the Volkswagen Polo?

Volkswagen Polo oil viscosity ranges between 12.5-16.3. Polo maintenance: Use genuine 5W-40 oil, opting for semi-synthetic oil from reputable brands. Alternatively, mineral oil can be used, but the maintenance interval should be shortened to 5,000 kilometers. Semi-synthetic oil can extend the interval to 7,500-10,000 kilometers. It is recommended to use 5W-40 or 10W-40 oil. Oils such as 0W-30 or 0W-20, which are suitable for Japanese cars, are not appropriate for the Polo. Engine oil requirements: The general requirements for the engine are small size, lightweight, compact structure, and high power output, which means the unit friction surface bears a significant load. In addition to frictional heat, the engine is also affected by combustion heat, leading to high temperatures on the friction surfaces. This causes the lubricating oil viscosity to decrease, making it difficult to form an oil film. High-temperature, high-pressure combustion gases in the combustion chamber can leak into the crankcase through the gaps between the piston, piston rings, and cylinder liner. These gases are the result of complete and incomplete combustion of fuel and a small amount of lubricating oil, consisting of gases and certain particulates (soot), which typically become the main components of crankcase blow-by. This contaminates the lubricating oil and, under certain conditions, accelerates its oxidation. The lubricating oil required around the combustion chamber enters through the gaps between the piston and cylinder liner and between the valve stem and valve guide, making oil supply more challenging.
