Is it better to use 92 or 95 octane fuel for Golf 6?

According to the official vehicle manual recommendation, Golf 6 should use 95 octane fuel. In addition to checking the suitable fuel grade in the vehicle manual for Golf 6, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane fuel, while those with a compression ratio between 10.0-11.5 should use 95 octane fuel. However, with the application of some new technologies nowadays, the fuel grade cannot be solely determined by the compression ratio. A high compression ratio can also be adjusted to use lower octane fuel. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally speaking, the higher the fuel grade, the higher the octane number and the better the anti-knock performance. 92 octane fuel contains 92% isooctane and 8% n-heptane, while 95 octane fuel contains 95% isooctane and 5% n-heptane. If Golf 6 occasionally uses the wrong fuel grade, simply switch back to the correct fuel grade after using it up. However, long-term use of the wrong fuel grade may have the following effects: For vehicles recommended to use lower octane fuel, using higher octane fuel by mistake will not cause damage. However, the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in actual driving experience. For vehicles recommended to use higher octane fuel, using lower octane fuel may cause engine knocking. Due to the significantly lower octane number, the fuel's ignition point decreases and may ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it's mild knocking, it only increases noise without obvious damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibration not only affects driving stability but also causes abnormal wear on pistons and cylinders, and in severe cases, may lead to cylinder scoring.

What does the 'A' symbol on a car mean?

The 'A' symbol on a car represents the auto start-stop function. There is an auto start-stop indicator light on the dashboard, as well as an auto start-stop switch inside the car, both marked with the letter 'A'. Cars equipped with auto start-stop have an indicator light on the dashboard. If the auto start-stop system is functioning properly, the indicator light is green; if the system is not working correctly, the light turns yellow or red. Auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts it when it's time to move forward again.

What does AQS in cars mean?

Automotive AQS refers to the Air Quality Sensor in vehicles. This sensor can detect air turbidity, humidity, and toxicity, and can control the air conditioning's internal and external circulation. The AQS system is highly sensitive to vehicle exhaust. In urban traffic congestion, the AQS system will automatically close the external circulation and activate the internal circulation. Vehicles equipped with the AQS system will also have automatic air conditioning, which is more intelligent than standard automotive air conditioning. Car air conditioning is an essential comfort feature in vehicles and should be cleaned annually. Otherwise, numerous bacteria may proliferate within the air conditioning system, and the air blown out when turned on may carry an unpleasant odor.

What methods are used to clean excessive sludge inside the engine?

Methods for cleaning excessive sludge inside the engine: Before changing the engine oil, add the sludge cleaner into the engine through the oil filler port, then start the engine and let it idle for 5 to 10 minutes. After that, turn off the engine and drain the sludge cleaner along with the old oil. It is recommended that car owners perform a simple sludge cleaning every 20,000 to 40,000 kilometers. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy.

What does OBD in cars mean?

OBD in cars refers to the On-Board Diagnostics system. The OBD interface in a car is typically located below the steering wheel on the left side. The primary function of the On-Board Diagnostics system is to monitor the operating condition of the engine. During engine operation, the combustion of fuel produces exhaust gases, and the OBD system continuously monitors whether the vehicle's emissions exceed the standard limits. If the vehicle's emissions exceed the permissible levels, the OBD warning light will immediately alert the driver. The On-Board Diagnostics system not only monitors vehicle emission indicators but also checks the engine, catalytic converter, particulate filter, oxygen sensors, emission control system, fuel system, and more. It continuously monitors potential safety hazards in the vehicle to ensure its safety performance.
