5 harmful effects of putting too much oil in your car
(Baonghean.vn) - The oil level directly affects the "lifespan" of a car engine. Putting too much lubricating oil in a normal engine only causes the engine to overheat - in the case of a small amount of excess. However, if there is too much excess oil, it will have unpredictable consequences.
1.Oil with air bubbles
 |
When you accidentally add more oil than is needed, the excess oil has no place to circulate. When the engine starts and the shaft rotates, the excess oil will foam because it is mixed with air. Foamy oil cannot lubricate effectively, and cannot even circulate, leading to overheating and damage to the engine parts.At that time, the Check Engine warning light may come on.
2. Great pressure on engine parts
 |
There are oil seals at the top and bottom of the crankshaft that prevent oil from leaking out of the engine. If the engine is filled with too much oil, the pressure inside the engine will increase; as a result, a lot of pressure is created on the oil seals at the top and bottom of the crankshaft, which are quite fragile and can easily cause oil to leak out of the engine.
The more dangerous thing that can happen here is that oil can overflow the flywheel and cause the clutch to slip.
3. Seal and Gasket are open or torn
 |
Welds and gaskets serve to seal gaps and increase the connection when assembling parts. When too much oil is added, beyond the needs and endurance of the engine, the excess oil can create additional pressure in the system, tearing the joints and causing many leaks.
When the seals and gaskets are leaking, the oil in the system will be lacking (after leaking too much), and needs to be added constantly...
4. Damage to crankshaft and connecting rod
 |
Too much oil causes the crankshaft and connecting rod to have more friction when in contact with the lubricating oil. The excessive resistance of the oil can cause them to bend; in more serious cases, it can cause the engine to break.
5. Engine oil leaks into the combustion chamber
 |
ViscousToo much oil can cause oil to bubble up into the combustion chamber when the engine is running. This causes the oil to burn along with the gasoline and causes black smoke in the engine exhaust.
This condition, if left untreated for a long time, will clog the catalytic converter; more dangerously, it can lead to a broken turbo engine.
* How to handle when pouring too much oil
Before adding oil, consult your owner's manual to find out how much oil to use. While adding oil, use the dipstick to check the oil level in the tank...
If you pour over a quart - it's not a concern.
Excess of 2 quartz is too much; excess of 3 quartz will certainly cause great damage.
When you have poured too much oil, you must drain the oil immediately by jacking up the car, getting under the car, removing the drain plug at the bottom of the oil tank, and slowly draining the oil... The job is not difficult, it just takes a little more time.
