Cars are still a luxury for most people. Car owners attach great importance to maintenance of their cars. Especially when car has just been bought, car is in a break-in period and needs protection.
This method is mainly for manual transmission models. When driving a manual transmission model during break-in period, gear change should be timely and appropriate, avoid misbehavior of low speed high gear and high speed low gear, and do not use gear for a long time (of course, use higher gear if speed is high (exception).
Try to avoid hard braking. Emergency braking not only affects brake system during break-in, but also increases shock load on chassis and engine of car.
Do not work under heavy load for a long time. Continuous operation of engine under high load for a long time can easily cause increased wear on parts, especially in new cars. Long highway driving is a high load job for a new car engine.
Avoid long periods of full load operation. A new car often runs at full load during its break-in period, which is considered overload, which puts more stress on engine and gearbox. Excessive engine power output due to high load will cause excessive wear of parts in long run.
Change oil in time. During break-in period, engine is in a critical “gradual entry” stage, and smallest metal chips generated by its components will be mixed into engine oil. If engine oil is not changed in time, this will aggravate engine wear.
Do not travel long distances. Long-term operation of a new car increases time of continuous operation of engine and increases wear of parts. If necessary, you should take a short rest after driving for 2-3 hours. Avoid overloading and restarting vehicle with a full load, this will damage machine parts. Therefore, during first 1000 km, domestic cars should not exceed 75%-80% of rated load, imported cars cannot exceed 90% of rated load In addition, try to choose a better road surface to avoid excessive vibration, collision or emergency braking reduces load on body and power system. Try to fill in better quality gasoline Engine oil used in new cars should not be lower than label specified by manufacturer. Try to fill in best quality gasoline (the brand of gasoline may not be of very high quality, but it should be clean). Don't add anti-wear oil to run out of mileage, but insufficient break-in.
