Reasonable selection of engine oil (click to review)

So how to judge your car?

Do you need to change the oil?

When do you need to add oil?

Park the vehicle on a flat ground. When the vehicle is cold, first pull out the oil dipstick and clean it, then re-insert it into the hole of the oil dipstick and wait for a while. Then pull it out again to check the oil quantity accurately. If it is a hot car, you should wait for a few minutes after the engine is turned off and wait for the oil to fully return to the oil pan before measuring.

The normal oil quantity should be above the scale mark B area, but not higher than the scale mark C area. If the oil quantity is lower than that in area B, it should be added in time; if the oil quantity is lower than that in area A, it should be added immediately.

Harm of too much or too little oil

Too little oil.

When the fuel quantity is lower than the scale A area, the continuous running of the vehicle will aggravate the wear of engine parts, shorten the service life of the engine, and even cause the engine bearing bush to be burned and scrapped. Therefore, when the amount of engine oil is too small, it should be added immediately to ensure the normal working state of the engine.

Too much oil

When the fuel quantity is higher than the scale C area, the running resistance of the engine will increase, and the engine will feel sluggish when starting, resulting in insufficient driving power. Be alert to the leakage of engine oil, which will cause carbon deposition when the engine burns engine oil, which will make the engine working condition worse and reduce its working ability. Therefore, if it is found that there is too much engine oil, it is necessary to release the excess oil in time to ensure the normal operation of the engine.

How to check the quality of oil products?

Use the oil dipstick to drop the oil on the inspection paper to observe its melted color. If it is light yellow, it means that the oil is clean. If the oil is medium yellow, it can continue to be used without oil change and maintenance; When the oil color turns black, it means that the oil filter needs to be changed to maintain the engine.
