CR-V oil dilution has not been resolved. Below is a detailed introduction to the CR-V oil dilution issue: 1. The 2019 CR-V has shown significant improvement, but it still uses the same 1.5T engine without substantial changes. 2. The 2017 CR-V is equipped with a 1.5T direct-injection turbocharged engine. Below is extended information on the effects of excessive oil: 1. Can lead to crankcase explosion. 2. The engine exhaust pipe emits blue smoke. 3. Piston ring sticking and fuel injector clogging. 4. Reduces engine output power. 5. Oil leakage. Below is extended information on the functions of engine oil: 1. Cushions the impact load on pistons, piston pins, connecting rods, and crankshaft bearings. 2. Forms a sealing ring between the piston rings and pistons, reducing gas leakage and preventing external pollutants from entering.

As a CR-V owner, I have firsthand experience with the oil dilution issue. My 2018 CR-V once encountered this problem where the oil level inexplicably rose over time, and it even smelled like gasoline. I was quite alarmed at the time and immediately drove to the dealership. The technician explained it was due to a design flaw in early direct-injection engines, causing fuel to mix into the oil pan and dilute the oil. Fortunately, Honda acted swiftly and issued a recall in 2019, providing a free software update for my vehicle that adjusted the engine warm-up time. Since then, the oil level has remained stable with no further issues. I've heard that newer models from 2021 onwards have design optimizations that essentially eliminate this problem, so prospective buyers of new CR-Vs can rest assured. For owners of older models, it's advisable to regularly check the dipstick and seek immediate dealership inspection if any abnormalities are detected. Using higher-quality engine oil during maintenance can also help prevent potential issues. Overall, this matter has been satisfactorily resolved, and I now drive with full confidence.

What is the maximum wading depth of the Mercedes-Benz GLC260?

According to official information, the maximum wading depth of the Mercedes-Benz GLC260 is 600mm. Common tire specifications are 235/55R19, with a body length of 4764mm, and it is a 5-door, 5-seat SUV. The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 centimeters, while SUVs have a higher maximum wading depth, but it is still best not to exceed 50 centimeters. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 centimeters, the Audi A4 has a maximum wading depth of 32 centimeters, the Volkswagen Sagitar has a maximum wading depth of 30 centimeters, the Land Rover Range Rover has a maximum wading depth of 90 centimeters, the Jeep Compass has a maximum wading depth of 48 centimeters, and the Highlander has a maximum wading depth of 45 centimeters. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when a vehicle is wading through water, different measures should be taken by the owner depending on the depth and the vehicle's characteristics, as follows: If the wading depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly concentrated at the bottom of the car, which could lead to circuit disconnection, damaging critical electrical components and preventing the car from starting normally. If the wading depth reaches the height of the intake pipe, it is extremely dangerous. Driving directly into such a water depth could cause the vehicle to stall immediately, resulting in permanent damage to the engine or rendering it unusable.

Should You Use 92 or 95 Octane Gasoline During the Vehicle Break-in Period?

Whether to use 92 or 95 octane gasoline during the vehicle break-in period should be determined based on the recommendations in the official car owner's manual. In addition to checking the appropriate gasoline grade in the owner's manual, you can also find it on the fuel tank cap, which is usually labeled. Typically, the gasoline grade can also be determined by the engine's compression ratio. Cars 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. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the use of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines 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. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after the tank is empty. 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 the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane value is too low, the gasoline's ignition point decreases and it may ignite prematurely during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is mild, it may only increase noise without significant damage to the engine. However, if the knocking is severe, it indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What are the hybrid models available?

Hybrid models include: Toyota Camry, Honda Accord, Spirior, BYD Song, Audi A8, Q5, Toyota Corolla, Levin, Lexus ES, BYD Qin, Geely Borui GE, Honda CR-V, Buick Regal, LaCrosse, Ford Mondeo, Cadillac XT5, Malibu XL, Nissan Murano, Lincoln MKZ, Acura CDX, etc. Hybrid vehicles offer high fuel economy and superior driving performance.

What are the four wires of a motorcycle ignition switch?

Motorcycle ignition switch has four wires: positive input, positive output, negative power supply, and kill switch wire. The following details these four wires: 1. Red wire: positive input, the thin wire with a fuse coming from the battery. 2. Black wire: positive output controlled by the key, forming a closed circuit with the red wire to supply power to all vehicle electrical components. 3. Green wire: negative power supply. 4. Black/white wire: kill switch wire controlled by the key, forming a closed circuit with the green wire to control the ignition system for engine shutdown.

What does APS in the car mean?

APS in the car stands for Accelerator Pedal Sensor. Here is the related introduction about the accelerator pedal: 1. Function: The accelerator pedal, also known as the throttle pedal, primarily controls the opening of the engine throttle, thereby regulating the engine's power output. Traditional accelerator pedals are connected to the throttle via a throttle cable or linkage. 2. Working Principle: Electronic throttle accelerator pedals are equipped with displacement sensors. When the driver presses the accelerator pedal, the ECU collects the opening changes and acceleration from the displacement sensor on the pedal. Based on preset algorithms, it determines the driver's intent and then sends corresponding control signals to the engine throttle control motor, thereby adjusting the engine's power output.
