After changing the oil, check the dipstick to see if the oil is appropriate, and check whether the oil is clean.

This should be to clean the previous one first, and then add the new one.

Look at the inside of the oil tank to see if it is clean, check the dipstick and see the amount.

It depends on whether the engine oil is clean, and it should be in moderation, not too much, not too little.

It's best to ask a professional about this, otherwise it's easy to suffer a big loss.

It is not troublesome to change the oil in the car, as long as there is a place and tools, if there is no vehicle lift or gutter, it is not very convenient to change the oil.

Hello, changing the oil is not troublesome, changing the oil is routine maintenance, I hope mine can help you, hope.

Changing the oil is not very troublesome, it can be discharged at the oil pan bolt, or you can use the suction pump to change the oil at the low pumping of the dipstick pipe and change the oil filter element at the same time.

It is very simple to not be troublesome, but it is not recommended to change it yourself at home, it is recommended to go to the repair station to replace it.

If all the tools are available, and there is a lifting frame or trench, the process sequence is fully controlled, and it is not troublesome to replace it. The oil label must be accurate, and the oil plug gasket of the oil must be replaced with a new one. In addition to the cost, you can also try to keep the old oil clean.

After changing to new oil, remember to look at the oil scale, within the set value, not too little or too much.

1. The oil volume is insufficient, so that the oil volume of the oil pump is reduced or the pump cannot be pumped due to air intake, resulting in a drop in oil pressure, which leads to the problem of oil light on.

2. The engine temperature is too high, which is easy to make the oil thinner, from the fit gap.

The oil pressure drops, which leads to the problem of the oil lamp being lit.

3. Crash. When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the oil pump to fail or the oil output is insufficient, which will cause the problem of oil lamp on.

4. a crankshaft. Improper matching gap between large and small tiles, too tight will increase the oil pressure, too loose will reduce the oil pressure; Oil filter, suction plate.

Blockages can likewise reduce oil pressure.

5. Damage or failure of the oil return valve: when the spring fatigue of the oil return valve of the main oil channel is softened or adjusted improperly, and the mating surface of the valve seat and the steel ball is worn or stuck by dirt and closed tightly, the oil return volume will increase significantly, and the oil pressure of the main oil channel will also decrease.

6. Improper selection of engine oil: when the wrong or improper brand selection is used, the leakage will be increased due to the low viscosity of the engine oil when the engine is running, so that the oil pressure will be reduced; There is oil leakage and blockage in the oil pipeline.

Hello, this is not a hassle.
