What oil should be used for Corolla 1.2T maintenance?

How long should a sedan be preheated?

Sedans only need about one minute of preheating. The reason for preheating is: After the car has been parked for a long time, the engine oil flows back to the oil pan at the bottom of the engine. When starting, the upper part of the engine lacks oil and lubrication. The purpose of preheating is to raise the temperature of the engine oil and improve its lubrication effect. The functions of preheating are: 1. Heating the antifreeze to improve the car's starting speed; 2. Maintaining the temperature of the engine block when the car is not in use, especially in low temperatures; 3. Preheating the engine oil to ensure it remains fluid for immediate circulation throughout the engine upon starting.

How many hours can you sleep without opening the car window?

It is not safe to sleep in a car with the windows closed, as it can be fatal in severe cases. Here are the relevant details: 1. Hazards: If you sleep in the car for an extended period with the windows tightly shut and the air conditioning on recirculation mode, the confined space of the car will cause the oxygen inside to deplete due to human respiration, while the carbon dioxide exhaled will accumulate. When the carbon dioxide concentration reaches a certain level, it can lead to unconsciousness and brain hypoxia, with severe cases potentially resulting in death. 2. Avoid sleeping in a car with the heater on: When the engine is running, incomplete combustion of fuel can produce high concentrations of carbon monoxide. If the car is stationary with the heater on and the windows closed, the carbon monoxide emitted by the engine will accumulate inside the vehicle, gradually increasing in concentration and making it highly likely for occupants to suffer from carbon monoxide poisoning.

What does 2.75-18 tire mean?

In the 2.75-18 tire, "2.75" refers to the tire width of 2.75 inches, which is 69.85mm, and "18" refers to the inner diameter of the tire or the outer diameter of the rim, which is 18 inches, or 457.2mm. The 2.75-18 tire is a standard tire, where the preceding numbers represent different attributes. For example, a 90/90-18 is a low-profile tire, where the first 90 indicates the tire width in millimeters, the second 90 represents the aspect ratio, and 18 again refers to the inner diameter of the tire or the outer diameter of the rim. This is expressed using the metric system. Tire model markings often appear as: 215/70R15, where the numbers mean: 215 is the tire section width in mm (typically ranging from 145–285mm in 10mm increments), 70 is the aspect ratio (the ratio of tire sidewall height to tire section width, with 70 representing 70%). Generally, tire aspect ratios range between 30% and 80%. For daily tire maintenance, pay attention to the following points: Regularly inspect the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually become shallower. If the tread is worn flat, it loses its water drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may also pose a risk of blowouts at high speeds. Additionally, promptly remove pebbles stuck in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may degrade rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool overheated tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear due to dragging against the road surface.

Does Washing the Car After Waxing Have Any Impact?

Washing the car after waxing has no negative impact. You can wash the car when it gets dirty or after rain. However, it's important to inform the detailing shop when the wax was applied, as only regular water is needed for washing after waxing. Applying solid wax protects the car's paint, preventing marks from rain or chemical substances like bird droppings. Below is additional information: 1. The role of waxing: As a traditional aspect of car care, waxing primarily serves to waterproof and protect against acid rain. The wax reduces water droplet adhesion on the car's surface significantly, with effectiveness ranging from 50% to 90%. It also protects against high temperatures and UV rays. With increasing heat, cars exposed to sunlight for extended periods are prone to paint aging and fading. 2. Car polishing: Polishing is a step in the car detailing process, performed before waxing, sealing, or coating to achieve a mirror-like finish. Sealing or coating requires thorough polishing first. Without polishing, the paint surface remains uneven, significantly shortening the duration of the sealant's effectiveness and preventing long-term adhesion.
