Should Corolla use 92 or 95 octane gasoline?

According to the official vehicle user manual recommendation, Corolla should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle user manual, Corolla owners can also find this information on the fuel tank cap, which will be clearly marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles 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. However, with the application of new technologies nowadays, 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, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, 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 Corolla occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. 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 number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in practical driving experience. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstable. If it's only mild knocking, the main effect is increased noise with no significant damage to the engine. However, if noticeable knocking occurs, it indicates severe engine conditions. The vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, and in severe cases, can lead to cylinder scoring.

Can I go to any 4S store for the first maintenance?

The first maintenance can be done at any 4S store of the same brand. You need to bring the first maintenance voucher and the vehicle's maintenance manual. The first maintenance is free and relatively simple, mainly involving an oil change and replacing the oil filter. When a car is newly purchased, it is in the break-in period, and the first maintenance should be done after this period. Once the vehicle enters the maintenance workshop, the owner should personally follow along to observe the entire maintenance process, especially to supervise the materials used by the maintenance workers and their work attitude. Following the process also allows the owner to learn some simple repair techniques and understand the basic structure of the car, which is very practical for dealing with sudden emergencies on the road in the future.

Why Can't the Handbrake Be Pulled?

The reasons why the handbrake cannot be pulled are as follows: 1. The pull wire has been used for a long time: Rust inside the pull wire causes it to be unable to be pulled, and the pull wire needs to be replaced. 2. The gap is too small: This causes the handbrake to be unable to be pulled, and a mechanic can adjust it. The handbrake does not need to be pulled too tight; generally, 4 to 6 ratchet teeth are sufficient. 3. Handbrake: The parking brake, commonly known as the handbrake, functions to provide resistance to the car when parked, preventing the car from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. There are different types of parking brakes, operated either by hand or foot through mechanical mechanisms. High-end cars are gradually adopting electronically controlled parking systems, commonly known as electronic handbrakes.

Is the first maintenance at 5,000 kilometers or 3,000 kilometers?

The first maintenance can be done at 3,000 kilometers, but it must be done by 5,000 kilometers. Given the road conditions in China, changing the engine oil more frequently is better for the car, especially in urban areas with frequent traffic congestion and stop-and-go conditions. During the break-in period, new cars often operate at low speeds with low RPMs, leading to more sludge deposits in the engine due to break-in impurities. Therefore, performing the first maintenance at 3,000 kilometers is normal. Once the vehicle enters the maintenance workshop, the owner can follow along to observe the entire maintenance process, particularly to supervise the materials used and the diligence of the maintenance workers. Following the process also allows the owner to learn some simple repair techniques and understand the basic structure of the car, which can be very practical for handling unexpected emergencies on the road in the future.

What to Do If the First Maintenance Is Overdue?

If the first maintenance is overdue and has not been performed yet, it is recommended that the car owner immediately go to the 4S shop for the first maintenance. The mileage for the first maintenance is generally 5,000 kilometers, and the owner must go for the first maintenance on time. The first maintenance for a car is usually very simple, typically requiring only an oil change and an oil filter replacement. Engine oil is very important for the engine; it is often referred to as the 'blood' of the engine. Inside the engine, oil serves to lubricate, cool, clean, and seal. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in a base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers.
