What kind of oil is recommended for the Yaris?

Toyota Yaris-specific oil manufacturer recommends using 5W30 semi-synthetic oil. In fact, 0W20, 5W20, 5W30, and 10W30 can all be used. However, in cold regions, 10W series oil makes engine starting difficult, so it is recommended to use 0W and 5W series oil. The most suitable oil for Toyota Yaris is 5W30 semi-synthetic. The following is an introduction to the relevant content of engine oil: 1. There are 4 types of summer oil, 6 types of winter oil, and 16 types of all-season oil. The summer oil grades are: 20, 30, 40, 50, 60. The larger the number, the greater the viscosity and the higher the maximum applicable temperature. 2. The winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the minimum applicable temperature.

How to Use Oil Film Remover?

Removing the oil film layer on the glass surface can also remove ordinary dust layer by layer. Because hot water can provide thermal energy to molecules, and after gaining energy, the molecules move more vigorously, this physical adsorption layer will be washed away. Then clean it. Acetic acid is a weak acid that can decompose most calcium deposits, ultimately cleaning the glass oil film. Then dry it with a cloth. After using this oil film remover, a protective film will form on the glass surface, slowing down the formation of oil film.

What is the Difference Between Single-Axle and Double-Axle Vehicles?

Single-axle and double-axle vehicles differ in the following aspects: 1. Number of drive axles: A double-axle vehicle has two drive axles, while a single-axle vehicle has one. 2. Load capacity: Single-axle trucks generally have a smaller load capacity, typically 2-5 tons, with four wheels at the rear. Double-axle vehicles have a larger load capacity, with the front single axle carrying 7 tons and the rear double axle carrying 18 tons, totaling 25 tons. 3. Off-road performance: Double-axle vehicles perform better off-road than single-axle ones, as single-axle vehicles are more prone to rear differential and axle shaft failures. 4. Additional information: A vehicle's drive axle usually consists of components such as the main reducer, differential, wheel drive mechanism, and drive axle housing. Steering drive axles also include constant velocity universal joints.

What are the reasons for the engine malfunction indicator light to illuminate?

The engine malfunction indicator light may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors referred to here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine malfunction indicator light. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the malfunction light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging problems: The intake turbocharging pipeline and turbocharger can also cause the engine malfunction light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If there is an issue with the vehicle's intake, it may lead to engine pipeline blockage, and in severe cases, trigger the engine malfunction light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust problems: Exhaust system faults can also trigger the engine malfunction light. Issues such as rear oxygen sensor failure, catalytic converter failure, exhaust camshaft and bearing failure can all cause exhaust problems, with the catalytic converter being the most common. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-theft system malfunction: If the vehicle's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the malfunction light. If the engine malfunction light illuminates, follow these steps: First, check if the engine is running normally, and if there are any issues such as shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, 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. Wait for 5-10 seconds and observe if the malfunction light turns off. If the malfunction light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.
