Methods to distinguish genuine and fake engine oil: 1. Check the packaging appearance: Genuine engine oil packaging is more refined, with neat craftsmanship. The cap is a one-time seal, and the opening has a tin foil with the manufacturer's special mark. If these features are missing, it might be fake. Fake oil packaging tends to be rougher. 2. Observe the oil appearance: Genuine oil is light-colored, transparent, and free of impurities, suspended particles, or sediment. Fake oil is darker in color, may contain impurities or sediment, and can feel sticky when touched. 3. Smell the oil: Genuine oil has a mild, crystal wax-like scent, while fake oil has a strong, pungent odor. 4. Freezing test: Place both oils in a -21°C environment for several hours. Genuine oil will maintain good fluidity, while fake oil will almost solidify. 5. Oil price: Genuine oil prices are relatively stable. If the price differs significantly from other sellers for the same model, be cautious. 6. Shake the oil: Shake the oil to observe its fluidity and how quickly bubbles disappear. Genuine oil flows well, and bubbles dissipate quickly. Fake oil has poor fluidity, and bubbles disappear slowly due to missing or ineffective anti-foam agents. 7. Manufacturer’s official anti-counterfeiting verification: Look for anti-counterfeiting marks on the bottle or cap, such as laser labels, QR codes, special identifiers, serial numbers, or verification via official websites, customer service calls, or SMS. 8. Compare anti-counterfeiting and certification codes: The cap has an anti-counterfeiting code, and below it is a certification code. Both codes should match.

As a veteran driver with over a decade of experience, I can tell you that identifying genuine engine oil comes down to experience. Real oil has tightly sealed bottle caps that require significant force to twist open; its labels feature sharp, three-dimensional printing without blurring or ghosting; and it emits a mild, non-irritating odor. Counterfeit products often have crude packaging with crooked labels or air bubbles. Once, I bought cheap oil from a small shop to save money, only to end up with constant engine knocking that cost me thousands in repairs. Now, I only purchase from brand-authorized 4S dealerships and immediately scan the anti-counterfeiting QR code on-site. The tissue test is also effective: drop a bit of oil—genuine oil spreads evenly with a deep brown hue, while fakes appear lighter with visible particles. Remember, don’t be lured by low prices. Fake oil can destroy your engine in just months, and the money you save won’t cover the repair costs!

Does the Tharu 330 have a particulate filter?

Tharu 330 does not have a particulate filter. The Tharu uses the MQB platform, and the 330TSI model is not equipped with a GPF (Gasoline Particulate Filter). Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation. To check whether a vehicle is equipped with a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully check the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Check the label on the oil filler cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Check whether there is a cylindrical section behind the three-way catalytic converter on the exhaust pipe. If there is, that is the particulate filter.

In terms of the powertrain, the Porsche Macan is equipped with a range of engines including a 2.0T, a 3.0T V6, and a 3.6T V6. The 2.0-liter turbocharged engine delivers a maximum output of 235 horsepower, the 3.0-liter V6 twin-turbo engine produces up to 340 horsepower, and the 3.6-liter V6 twin-turbo engine generates a maximum of 395 horsepower, all paired with a 7-speed dual-clutch transmission. It is reported that the latter two engines may be featured in the Macan S and Macan Turbo models in the future. The three Michelin tires fitted on the Porsche Macan are: the newly launched Michelin Latitude Sport 3 summer tire, the Michelin Latitude Alpin 2 winter tire, and the Michelin Latitude Tour HP all-season tire. The introduction of the Macan fills the gap in Porsche's lineup for the mid-size SUV market.

How many coolant temperature sensors does the Malibu have and where are they located?

The Malibu has one coolant temperature sensor, located at the connection point between the upper hose and the cylinder head or at the thermostat. A temperature sensor (temperature-transducer) refers to a sensor that can detect temperature and convert it into an available output signal. Temperature sensors are the core component of temperature measurement instruments, with a wide variety of types. According to the measurement method, they can be divided into contact and non-contact categories, and based on the characteristics of sensor materials and electronic components, they are classified into thermistors and thermocouples. The functions and composition of the coolant temperature sensor are as follows: 1. Function: The coolant temperature sensor is installed on the engine block or cylinder head water jacket, in direct contact with the coolant, to measure the temperature of the engine coolant. The electronic control unit detects the temperature of the engine coolant based on this change—the lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit uses this change to measure the engine coolant temperature as a correction signal for fuel injection and ignition timing. 2. Composition of the automotive coolant temperature sensor: Its interior consists of a semiconductor thermistor—the lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit uses this change to measure the engine coolant temperature as a correction signal for fuel injection and ignition timing.

Should SUVs Use 92 or 95 Octane Gasoline?

SUVs can use 92 octane gasoline. This octane rating is recommended in the vehicle's official owner's manual. In addition to checking the appropriate gasoline grade in the owner's manual, the fuel filler cap will also indicate the recommended octane rating. Typically, the octane rating 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 octane rating cannot be solely determined by the compression ratio. High-compression engines can also be tuned to use lower-octane gasoline because factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the 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 an SUV occasionally uses the wrong octane rating, simply switch back to the correct one after the current tank is used up. However, long-term use of the wrong octane rating can have the following effects: For vehicles designed for lower octane ratings, using higher octane gasoline will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher octane ratings, using lower octane gasoline can cause engine knocking. Because the octane number is significantly lower, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will be generated during the upward stroke. This resistance makes the engine run very unevenly. 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, potentially leading to cylinder scoring in severe cases.
