Can you overfill your oil

In order to move lubricant throughout the motor, a pump pressurizes it and draws it up from the pan or sump , so it can be sprayed in key areas. Overfilling engine oil can raise the level of oil in the pan to the point where the crankshaft starts to make significant contact with the reservoir. Since it moves so fast, it can turn the oil from a liquid into a froth that the pump is no longer able to siphon and distribute.

At that point, the engine can starve from lubricant to the degree that serious damage is often the end result.

This could indicate that not enough oil is being pumped through the engine, particularly if the gauge readout is moving back and forth quickly. If you suspect that your engine has been overfilled with oil, shut it down and do not attempt to drive it anywhere. Place the plastic oil pan beneath the oil plug and loosen the plug until the oil drips.

Check again with the dipstick to ensure the correct amount of oil. Note: Some vehicles have a cover under the car that has to be removed before you can reach the oil plug.

For example, a 4-cylinder unit will require 3 quarts of oil, whereas a larger 6-cylinder engine may need approximately 6 quarts of oil. Always be careful that you fill in the right amount.

Certified Automotive Diagnostic Technician. Hello, My Honda car takes in a little below 4 quarts of engine oil that is 3. Two weeks back the garage around poured half quart more than the recommended quantity during oil change and the dipstick shows the oil level to be around one centimeter above the high mark.

The car has in the past two weeks run just over miles or around kms. Can this be a cause of check engine yellow light continuously lighting up on the dashboard after two weeks since I changed the engine oil? Sugar was poured in my oil tank. The oil was drained by the mechanic, When he replaced the oil he overfilled it. The oil was drained the following day after 96km There is oil coming out from the exhaust. When I start the engine in the morning there is some funny knock or noise from the engine.

Does this mean something is not right. What must I do. I just had my first oil changed,and my car is Honda Civic Hatchback Ex 1.

Catastrophic engine failure where the engine sustains enough damage that it cannot be repaired, but must instead be replaced. Excess engine wear from inconsistent oil pressure over time. Spark plug fouling, resulting in the need to replace spark plugs more frequently. Excess oil deposits in the catalytic converter. Leave a Reply Cancel reply You must be logged in to post a comment.

Overfilling the engine oil in your car can cause serious damage to your internal engine parts and eventually lock up your engine.

To remedy engine oil overfill in your car, you must first verify that the engine oil is actually overfilled and then drain the excess engine oil from your vehicle's oil pan. While it may not seem like a big deal to overfill the oil in your car, it can cause major malfunctions and potentially cost you thousands of dollars.

When too much engine oil fills the crankshaft in your car, the oil becomes aerated and is whipped into foam. This is caused by the high rotation of the crankshaft. Foamy oil cannot lubricate your car well, and in many cases it will cause oil flow to halt completely, overheating your oil and causing loss of oil pressure. The engine then becomes starved for lubrication and may potentially lock up.
