Are you curious about how much oil is too much for your car? You have landed in the right place.
As a car owner, you must know how important it is to look after your car’s every need. One of the most crucial tasks is to change the oil in the given period. However, it’s completely normal to make the mistake of overfilling the car engine.
The amount of oil depends on your engine size. However, most engines need three to eight quarts of oil. A four-cylinder engine needs three quarts of oil, but a larger cylinder engine will need around six quarts. You’ll also find the information on engine oil capacity in your owner’s manual.
This article finds out how much engine oil your car engine can take and how much is too much. In addition, it will also address how to drain the extra oil.
How Much Overfill Oil Is Ok?
A little over the full mark should not cause any problem in your engine. In many cases, this unintentional overfill settles once you start the engine. Furthermore, an approximate value of 20% overfill should not cause any problem.
We recommend filling the oil up to the full mark for maximum engine safety. Furthermore, the extra oil expands when the engine heats up and might contact the engine’s other components. However, you can drain the excess oil out to the appropriate levels.
Is One Quart of Oil Too Much?
You can overfill most car engines by one quart and use them without undesirable consequences. However, keep in mind that it is not recommended to fill the car engine more than the recommended oil level. Fortunately, you can decide the appropriate oil level by using a dipstick when the engine is warm.
There are several indications to identify if your engine has too much oil. Signs like thick white smoke and oil leaks after turning on the car are the signs of oil overfill. Excess oil fills the crankshaft creating foam that stops the oil flow resulting in overheating the engine.
What Happens if I Overfill My Engine?
There are also drawbacks to overfilling of oil. The most common is that foaming occurs when a slick lubricant becomes a sudsy fluid with air bubbles, reducing its lubricating and cooling effects. As frothy oil is more difficult for the oil pump and distributes throughout the engine. Whereas, some moving parts may not receive the amount of oil needed which can cause engine damage.
Overfilling the engine also raises oil pressure and strains the seals and gaskets to prevent oil from leaking out. The extra pressure also causes the seal and gasket to wear out faster over time.
How to Remove Excess Oil?
Overfilling your car engine is a common mistake. With the risks associated with excess oil in mind, figuring out how to drain the extra oil should be one of your primary concerns.
Here are some ways to remove the extra oil:
1. Unbolt the Oil Plug to Drain Out Excess Oil
To unbolt the oil plug, first, crawl under the car and find the oil plug. Then place the drain pan straight under the oil plug to collect the excess oil. Now, slowly unbolt the oil plug with the socket wrench. You need to be watchful because there is a chance of spilling and wasting the oil.
Allow the oil to drain for a while until the draining slows down. Also, use the dipstick to check the level and wait till the oil level returns to normal. Finally, tighten the oil plug, and you finish filling up the engine.
2. Using Dipstick Tube to Check the Oil Level
Another effective method of removing excess oil from the engine is using a dipstick tube. Also, it’s preferable because you don’t need to get under the car or loosen the oil plug to drain the oil.
Place the dipstick and remove it. Take a vinyl tube and insert it into the dipstick tube. Also, ensure that the vinyl tube goes all the way into the engine. Now, insert the free end of the tube into your mouth and suck hard until the tube is nearly empty.
After the air gets removed, the oil rises to the surface. Let the oil drain by placing the other end into a container. Once you siphon enough of it, remove the tube from the engine and confirm the oil level.
3. Use an Oil Extractor Pump
The next approach to remove oil is with vacuum oil extractor pumps. While these are costly, they are also handy. You can assemble the extractor pump and use the long straw attachment that goes down inside the dipstick tube. Now use the pump to extract oil from the engine. Continue pumping until the oil level drops to the acceptable range.
You’ll require an extended amount of time to make the extractor operate. Also, you’ll need to crawl under the car and need space for draining oil. However, it does the work perfectly.
4. Ask For Help From a Professional
Lastly, another method of removing excess oil is getting professional help. Consulting a professional is the best thing to do if draining extra oil from the engine at home is impossible. You can take your automobile to a repair shop and get the service from a professional mechanic. Do not drive the vehicle; instead, tow it to the mechanic. This measure will help you avoid any engine damage.
So, that’s all for now. In this article, we’ve discussed the effects of overfilling oil in a car engine and how to remove it.
Overfilling is a common mistake, and there are ways of correcting it. Most of these techniques do not require any technical skills. We hope this article has cleared all your questions about how much oil is too much. Just remember to check your oil levels regularly. Also, follow what the manufacturer has recommended and routine maintenance to improve the life of your vehicle.
