Here is the relevant introduction about mistakenly adding the wrong fuel: 1. Adding diesel to a gasoline car: The vehicle may experience shaking, black smoke from the exhaust, or even fail to start. If driven forcibly, the entire fuel system could be damaged, and the engine might even be ruined. Solution: Contact a specialized repair shop as soon as possible to clean the fuel tank and fuel system, followed by a comprehensive engine inspection. Avoid starting the engine to prevent further damage. 2. Adding gasoline to a diesel car: Initially, the vehicle may start, but after driving for a while, noticeable unstable idling, abnormal engine noises, and white smoke from the exhaust will appear. Compared to adding diesel to a gasoline car, if detected early and the fuel is replaced immediately, the engine can still function. Solution: Find the nearest repair shop to replace the gasoline immediately. It is also advisable to clean the fuel tank and fuel system and replace the fuel filter.

What Are the Consequences of Using 92 Octane Gasoline in a Passat?

According to the official vehicle manual, the Passat is recommended to use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, the Passat's fuel cap also indicates the recommended octane rating. 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. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade, as high compression ratios can still 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 Passat occasionally uses the wrong gasoline grade, simply switching back to the correct grade after consumption is sufficient. 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 number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, manifesting as poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
