It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates excessive carbon deposits in the engine, which requires treatment at a 4S shop. Once damaged, it will cause an imbalance in the engine's air-fuel ratio, leading to increased fuel consumption. The oxygen sensor should be replaced. During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly.

How long can a car run with a blown head gasket?

It is best not to continue driving a car with a blown head gasket. A blown head gasket can cause a rapid rise in coolant temperature and severe water shortage in the radiator. You should stop immediately and contact a tow truck to take the car to a repair shop for inspection and repair. Continuing to drive may lead to engine seizure or even severe engine damage, rendering it irreparable. Below are the symptoms of a blown head gasket failure: 1. Burnout between two cylinder edges: The car will experience a lack of power, and the engine will underperform. When the air filter is removed, abnormal noises can be heard at the intake pipe opening while the engine is idling. 2. Burnout connecting to the water jacket hole: The radiator may produce bubbles, overheat, and the exhaust may emit white smoke. 3. Burnout connecting to the oil passage: Some engine oil may enter the cylinder and burn, resulting in blue smoke from the exhaust.

How to Adjust a Car Pulling to the Right?

Methods to adjust a car pulling to the right: 1. Prepare a wrench, then turn the steering wheel all the way to the right to expose the rear of the left front wheel; 2. Loosen the nut with the wrench, then turn the left control rod clockwise to shorten it; 3. Repeat the previous step, turn the steering wheel all the way to the left to expose the rear of the right front wheel, similarly loosen the nut with the wrench first, then turn the right control rod counterclockwise to extend it. The solution to a car pulling to one side is to perform a wheel alignment. There are several tire-related factors that can cause a car to pull to one side, such as incorrect wheel alignment, uneven tread wear, unequal tire pressure, or imperfectly round tire shapes, all of which can potentially cause the car to pull to one side.
