Jetta VS5: Should I Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, the Jetta VS5 should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will also be marked. Generally, the gasoline 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 gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in the Jetta VS5, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value 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 gasoline, using lower octane gasoline can cause engine knocking. Because the octane value is much lower, the gasoline's ignition point decreases and may ignite prematurely during the compression stroke. If combustion occurs before the spark plug fires during the compression stroke, resistance will arise during the upward stroke. This resistance will make the engine run very unstably. If it's only mild knocking, it may just increase noise without significant damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What is the process for downgrading a driver's license?

Processing steps: The motor vehicle driver or agent must bring the required materials to the window of the vehicle management office branch or the driver's license management window of the traffic police detachment (brigade) in each district (county) to handle the procedure. If applying for a voluntary downgrade of the permitted driving model and license replacement at a vehicle management office other than the issuing location of the motor vehicle driver's license, the transfer procedures must be completed as required. II. Required materials: "Motor Vehicle Driver's License Application Form". Identity proof and a copy of the motor vehicle driver. Motor vehicle driver's license. Motor vehicle driver's license photo. If also applying for a license replacement upon expiration, submit the "Motor Vehicle Driver's Physical Condition Certificate". Three recent front-facing, bareheaded, white-background color ID photos (submit the digital photo collection receipt if required by local regulations). If applying for a voluntary downgrade of the permitted driving model and license replacement at a vehicle management office other than the issuing location of the motor vehicle driver's license, the transfer procedures must be completed as required, and the original "Motor Vehicle Driver's Physical Condition Declaration Form" must be submitted. If delegated, the power of attorney and the agent's identity proof and copy must also be submitted. Drivers holding licenses for large buses, tractors, city buses, medium buses, or large trucks must have their highest permitted driving model qualification revoked by the vehicle management office under the following circumstances, and the motor vehicle driver must be notified to complete the downgrade and license replacement within 30 days: Being involved in a traffic accident resulting in death and bearing equal or greater responsibility without constituting a crime. Having a record of 12 penalty points in one scoring cycle. Failing to participate in the review for three consecutive scoring cycles. If the motor vehicle driver fails to complete the downgrade and license replacement within the specified time, the vehicle management office shall announce the revocation of the permitted driving model qualification. After completing the downgrade and license replacement, if the motor vehicle driver applies to reinstate the revoked permitted driving model, they must have no record of 12 penalty points in the current and the most recent scoring cycle before application, and no involvement in a traffic accident resulting in death with equal or greater responsibility. Procedure for revoking the highest permitted driving model and completing the downgrade and license replacement: After passing the relevant examination, receive the "Motor Vehicle Driver's Illegal Full-Point Examination Information Feedback Notice" (for Class A and B licenses, the downgrade information will be noted on the notice). After the suspension period ends, present the ID card and the "Motor Vehicle Driver's Illegal Full-Point Examination Information Feedback Notice" to the traffic police team where the license was confiscated to retrieve the driver's license.

Will using 92-octane gasoline affect the Lavida 1.4T?

Using 92-octane gasoline in the Lavida 1.4T may affect the engine's lifespan, and it is recommended to use 95-octane gasoline. This gasoline grade is officially recommended in the vehicle's user manual. For the Lavida 1.4T, besides checking the appropriate gasoline grade in the user manual, the recommended grade is also indicated on the fuel tank cap. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio, as high-compression engines can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Lavida 1.4T occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This can reduce the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-octane gasoline, using lower-octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will be generated during the upward stroke, making the engine run very unstable. Mild knocking may only increase noise without obvious damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in extreme cases, cylinder scoring.

How to Clean Sludge in the Engine?

You can use a dedicated sludge cleaning oil. After draining all the engine oil, add the cleaning oil to the engine, let the engine idle for 15 minutes, and then drain the cleaning oil. Here is some extended information about the engine: 1. Over time, sludge or carbon deposits may form inside the car's engine. However, sludge is harmful to the engine as it can clog the oil passages, affecting the engine's lubrication. 2. The engine contains oil, which needs to be pumped by the oil pump to various parts requiring lubrication. If the oil passages are clogged, the oil cannot reach these parts, leading to increased engine wear.
