Is driving 100 kilometers in M1 gear harmful to the car?

Driving 100 kilometers in M1 gear will not harm the car. Any car can continuously use M1 gear, just like a manual transmission car can also keep driving in first gear. As long as you don't constantly rev the engine to 4,000 or 5,000 RPM, it's fine. The main impact of this driving method is on fuel consumption; driving continuously in low gears will result in very high fuel consumption. Below are some additional tips for saving fuel in cars: 1. Ensure the tire pressure is correct. 2. Use the lowest viscosity engine oil. 3. Maintain the car body properly. 4. Do not overdo "warming up" the car. 5. Do not start the engine when the car is not moving. 6. Avoid accelerating by stomping on the gas pedal.
I also drive a manual transmission car. Once, I accidentally drove in M1 gear for over half an hour in the city. At the time, I didn't notice anything, but later the engine sounded strange and started smoking. The mechanic said that driving in first gear can rev the engine up to 4,000-5,000 RPM, and driving 100 kilometers like this is like running a marathon every day, doubling the wear on pistons and valves, and increasing fuel consumption by half. Long-term driving like this can damage internal engine components and may even cause transmission system oil leaks. I recommend keeping an eye on the tachometer while driving and not exceeding 2,500 RPM, shifting up as soon as you start moving. If it does happen, get a comprehensive inspection—preventing problems is cheaper than fixing them later. Developing good habits can save you both hassle and money.
