Corolla uses Toyota Genuine ATF WS transmission oil. Symptoms of not changing the transmission oil include: 1. Decreased power - the vehicle responds sluggishly during acceleration with noticeable engine noise but no corresponding speed increase; 2. Difficult starts - at low gears, the engine revs up when accelerating but the vehicle covers less distance; 3. Transmission damage - overheating may occur, damaging bearings and gears; 4. Gearshift issues - jerky shifting, rough transitions, and unusual noises from the transmission. The transmission consists of gear transmission mechanisms and control mechanisms, whose function is to alter the speed and torque from the engine, either fixing or changing the gear ratio between the output and input shafts.

My Corolla just had its transmission fluid replaced. The manufacturer actually recommends Toyota Genuine ATF WS Automatic Transmission Fluid. This blue specialty oil is the best fit for the Corolla's CVT transmission, offering exceptional lubrication. During my last service at the dealership, the technician told me that this fluid effectively prevents transmission slippage and extends its service life. Of course, third-party brands aren't unusable either—options like Mobil's ATF3309 or Aisin's AFW6 also meet the standards. I'd recommend following the maintenance manual and changing the fluid every 40,000 kilometers for safety, since transmission repairs certainly don't come cheap.

What type of fuel should the Lamando 230 use?

The Lamando 230 should use 95-octane gasoline, as recommended in the vehicle's official user manual. In addition to checking the appropriate fuel grade in the user manual, you can also find this information on the fuel tank cap, where it is usually indicated. Generally, the fuel grade 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 even higher, 98-octane gasoline is recommended. However, with the use of newer technologies, the compression ratio alone cannot determine the required fuel grade, as high-compression engines can also be tuned to use lower-octane fuel. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the fuel grade, the higher the octane rating 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 the Lamando 230 occasionally uses the wrong fuel grade, simply switching back to the correct grade after consumption is sufficient. However, prolonged use of the wrong fuel grade can have the following effects: For vehicles designed for lower-octane fuel, using higher-octane fuel will not cause damage, but the increased octane rating 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 fuel, using lower-octane fuel can cause engine knocking. The significantly lower octane rating lowers the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, it creates resistance during the upward stroke. This resistance makes the engine run very unevenly. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

What type of oil is suitable for the New Alto?

The original oil brand for the New Alto is Suzuki. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The oil models recommended in the official manual for the New Alto are 0W-20 and 5W-20. Any oil model that meets these two specifications can be used. The viscosity of the oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, making the car's cold start smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the oil in the New Alto is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain. Use a special wrench to remove the oil filter. Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a bottle. Start the engine and let it run for 5 minutes. Check for oil leaks around the oil drain plug and oil filter. If there are any leaks, perform necessary repairs. After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.

How Often Should the Brake Pads of Changan Eado Be Replaced?

The official recommendation does not specify a fixed replacement cycle for the Eado's brake pads, as it largely depends on driving conditions and habits. Generally, a set of brake pads can last up to 100,000 kilometers if used properly. To determine whether the brake pads need replacement, you can use the following three methods: 1. Check the brake pad thickness: When the brake pads become very thin, braking performance significantly declines, affecting driving safety. New brake pads are typically about 1.5cm thick. When the thickness wears down to 0.5cm, you should increase the frequency of self-inspection. If the thickness is reduced to 0.3cm, immediate replacement is necessary, as this is the minimum safe limit for brake pad thickness. 2. Monitor the vehicle's dashboard warning light: Most cars have a brake warning light on the dashboard. When this light illuminates, it indicates that the brake pads have reached their wear limit and must be inspected immediately. All vehicles are equipped with such warning systems, though some directly sense the brake pad thickness, while others activate the warning light only when the brake pads are completely worn out and brake fluid levels drop critically. 3. Listen for unusual sounds: Brake discs are usually made of iron and can develop rust after prolonged parking, especially in humid or rainy conditions. When braking, a slight hissing sound may occur, which typically disappears after driving for a while and applying the brakes a few times. However, if the sound persists without improvement, the brake pads must be replaced immediately. This indicates that the wear indicators on the sides of the brake pads are directly grinding against the brake disc, confirming that the pads have exceeded their safe limit.
