Modifying the interior will affect the vehicle's annual inspection. Interior modifications: Mainly involve modifications to the vehicle's electrical systems, such as installing multimedia or upgrading the stereo. However, modifications that alter the vehicle's technical parameters—such as changing the intake and exhaust systems, widening the body, lowering the suspension, modifying braking components, or blindly upgrading high-beam headlights—are not legal under regulations. Precautions for vehicle performance modifications: Converting a single exhaust to a dual exhaust is not allowed, as it may alter engine parameters. Brake calipers can be modified, as this upgrade can improve the vehicle's braking performance. Currently, domestic traffic police are relatively lenient toward modifications that enhance braking performance. Replacing or reinforcing chassis suspension components is permissible, as it can improve the vehicle's handling and stability.

What does Castrol Edge FE mean?

Castrol FE engine oil refers to the latest titanium fluid formulation, which does not fall under the category of oil grades. For example, SN and similar designations indicate oil grades, while the titanium fluid series of oils all belong to the SN grade, so there is no conflict between the two. Related information: 1. Castrol FE engine oil: Castrol Edge utilizes advanced titanium fluid strengthening technology, making it a premium high-end engine lubricant. Infused with a liquid titanium formula, it possesses unique oil film self-adaptability, effectively reducing direct metal-to-metal contact under various driving conditions, thereby minimizing friction loss and ensuring optimal engine performance. 2. Oil grades: The API on engine oil stands for the American Petroleum Institute, with grades ranging from SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, to SN, with each subsequent grade being higher. SN grade is currently the highest level of engine oil. SJ is the standard from the 1990s, SL is the standard from 2001, SM is the standard from 2004, and SN is the standard from 2010.

What to Do When the Engine Malfunction Light Comes On in a Mondeo Zhisheng?

The engine malfunction light may come on due to the following 7 main reasons: Sensor failure: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which may trigger the engine malfunction light. Fuel/oil quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear and trigger the malfunction light. Poor combustion of air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by oxygen sensors and reported to the ECU, the malfunction light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake boost piping or turbocharger can also cause the engine malfunction light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: Problems with the vehicle's intake system may cause engine piping blockage, and in severe cases, trigger the engine malfunction light. A dirty air filter that hasn't been cleaned regularly can lead to intake problems. Exhaust issues: Exhaust system failures can also trigger the engine malfunction light. Common causes include rear oxygen sensor failure, three-way catalytic converter failure, exhaust camshaft and bearing failure, with the three-way catalytic converter being the most frequent issue. Using leaded gasoline, lead/silicon-containing lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause three-way catalytic converter failure. Anti-theft system failure: If the vehicle's electronic anti-theft system malfunctions, or if the anti-theft controller doesn't match the engine electronic controller, the anti-theft system may prevent the engine from operating normally while illuminating the malfunction light. When the engine malfunction light comes on, follow these steps: First, check whether the engine is running normally and if there are any issues like shaking or smoke emission. If so, avoid restarting the engine. Note: Never restart the engine if the red warning light is on. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake pedal, press the start button once or turn the key halfway to the ON position without depressing the clutch. The vehicle will perform a self-check after powering on. Observe whether the malfunction light turns off after 5-10 seconds. If the light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read trouble codes, identify the issue, and perform targeted repairs.
