Fourth gear corresponds to a speed range of 40-60 km/h. The speed ranges for manual transmission gears are as follows: 15 km/h for 1st gear, 25 km/h for 2nd gear, 35 km/h for 3rd gear, and 65 km/h for 5th gear. Below are some related details about gear usage: Relationship between gears and speed: Generally, start in 1st gear and shift to 2nd gear after traveling a few meters. When the speed reaches above 20 mph but below 35 mph, shift to 3rd gear. When the speed reaches above 35 mph but below 45 mph, shift to 4th gear. When the speed exceeds 45 mph, shift to 5th gear. The above applies to standard 5-speed transmission cars. For cars with 6 or more gears, you can upshift one gear for every additional 15 mph increase in speed. Additionally, when shifting gears, pay attention to the engine RPM; it's best to shift when the RPM is around 2500. Introduction to gear usage: Most cars have 5 forward gears and 1 reverse gear, with neutral in the middle. Use 1st gear for starting; 2nd gear for speeds between 20-40 km/h; 3rd gear for speeds between 40-60 km/h; 4th gear for speeds between 60-75 km/h; and 5th gear for speeds above 75 km/h.

After driving for so many years, I've seen quite a few manual transmission cars. The speed in fourth gear usually ranges between 60 to 90 km/h, depending on the car's displacement and power. Generally, in the city, I prefer shifting to fourth gear when the speed stabilizes around 60 km/h, keeping the engine RPM between 2000 to 3000, which is more fuel-efficient and smoother. On the highway, fourth gear can even push beyond 100 km/h, but it's not recommended as it strains the engine at high RPMs. It's best to rely on actual driving feel—when the engine sounds too loud, it's time to shift up or down. Getting the shift timing right not only extends the car's lifespan but also saves a lot on fuel. Experienced drivers know every car is different, so try it out with your own ride.

What is the difference between gasoline types?

98-octane, 95-octane, and 92-octane gasoline differ in the following aspects: Different quality levels: 98-octane gasoline has a higher octane rating, while 95 and 92-octane gasoline have lower octane ratings. Higher octane fuel provides better anti-knock performance, resulting in smoother engine operation. Different fuel consumption: 98-octane gasoline has lower fuel consumption, while 95 and 92-octane gasoline have higher fuel consumption. The higher the gasoline grade (i.e., the higher the octane content), the less likely it is to cause knocking, and the better the engine's anti-knock performance during combustion. Car owners should choose gasoline based on their engine's compression ratio. Vehicles with higher compression ratios should use higher-grade gasoline to ensure strong power output and lower costs while preventing engine knocking.

Is the Volkswagen Lavida Plus equipped with a timing belt or a timing chain?

Volkswagen Lavida models produced before May 2013 are equipped with timing chains, while those produced after May 2013 come with timing belts. Replacement cycle for timing chains: The chain is made of micro-alloy material and is lubricated by engine oil inside the engine. Theoretically, its service life can last until the vehicle is scrapped. However, the chain tensioner has a wear life of only 80,000 to 100,000 kilometers and needs to be replaced when the time comes. The purchase price of the tensioner is basically only one-tenth of that of a timing belt. Replacement cycle for timing belts: Timing belts generally need to be replaced after driving 60,000 to 80,000 kilometers. Once the timing belt breaks, the camshaft will definitely not operate according to the timing.

What are the differences between full-size and non-full-size spare tires?

The differences between full-size and non-full-size spare tires are: 1. Different sizes: The full-size spare tire has the same specifications as the four original tires of the car; the non-full-size spare tire is narrower or has a smaller rim size. 2. Different driving speeds: The full-size spare tire has no speed limit as long as it complies with traffic regulations; the non-full-size spare tire cannot exceed 80 kilometers per hour. 3. Different weights: The full-size spare tire weighs the same as the four original tires of the car; the non-full-size spare tire is lighter than the four original tires. The process of replacing a spare tire: 1. Loosen the screws; 2. Lift the vehicle with a jack; 3. Remove the screws that secure the wheel, turning counterclockwise to loosen and clockwise to tighten; 4. Remove the tire; 5. Replace it with the spare tire.

What is the tire pressure matching channel number for the Volkswagen Tiguan?

The tire pressure channel number for Volkswagen is 5053-65-16-10896. Strictly speaking, tire pressure refers to the air pressure inside the tire. Low tire pressure: Tire pressure is critical to the life of a tire. Both excessively high and low pressure will shorten the tire's lifespan. Low pressure increases tire deformation, leading to cracks on the sidewalls and causing flexing movements, which generate excessive heat, accelerating rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area, accelerating wear on the tire shoulders. High tire pressure: Excessively high pressure overextends the tire cords, reducing the tire's elasticity and increasing the load on the vehicle during driving. If impacted, it may cause internal cracks or blowouts. High pressure also accelerates wear on the tread and reduces puncture resistance.
