Every internal combustion engine requires oil to lubricate its parts. Vehicles have different size engines, depending on the weight and size of the vehicles themselves. The amount of oil that goes into the engine depends on the size of the engine. For most cars, the engine will need at least 5 quarts of oil or up to 8 quarts. If you have a small vehicle with a small engine, you use less oil. For example, a vehicle with a 6-cylinder engine needs 6 quarts of oil and one with a 4-cylinder engine needs 5 quarts of oil. If you have a V8 engine, then you’ll need 8 quarts of oil.
Oil is the blood of the vehicle. It prevents engines from overheating by reducing the amount of friction generated from its moving parts. There may be a cooling system included in the vehicle to assist in lowering the engine heat, but the oil is the main ingredient for cooling the engine. Plus, oil helps clean away the contaminants and debris from the components too. This allows them to function properly and without any setbacks.
Too Much Oil Effects
Oil changes are typically done ever 3,000 to 5,000 miles. Some people have the false impression that putting too much oil in the engine will allow its components to be lubricated even better. However, this is not the case because too much oil in the engine can actually cause the opposite to happen. Instead of thoroughly lubricating the components, the oil will not be able to lubricate them well at all.
When there is too much oil, the rotating crankshaft will cause air to make contact with the oil. Once that happens, the oil becomes very foamy and frothy while circulating through the running engine. There will be several air pockets within the oil as it becomes thicker. This will slow down its flow and ability to circulate through the components of the engine at the speed needed to keep it cool.
What’s worse is that the air contained tiny particles and debris which is introduced into the oil. This means that the oil is now contaminated and will reduce its effectiveness at lubricating the engine. As you can guess, the engine will overheat if its components are not lubricated properly. Then you’ll need to worry about all kinds of engine problems and damage.
Check Oil Level via Dipsticks
The best way to know if you have too much oil is to test the oil level with a dipstick. Most people use this to make sure they have enough oil, but you can also use it to make sure you don’t have too much oil. There should be markings on the dipstick which indicate “Add” and “Full.” Normally, you’d want the oil level to reach in between those two markings of the dipstick. But if the oil level goes past “Full,” then it means you have too much oil.

Drain the Oil soon if Too Much
So, what do you do when you have too much oil? The only thing you can do is drain the oil from the engine. You can do this by going to a professional auto shop or you can do this yourself. If you already know how to change your oil, then you are familiar with the process of how to drain it.
You first need to find the drain plug below the engine underneath the oil pan. This will require you to jack up your vehicle. Position a container below the drain plug. Unscrew the drain plug so that the oil drains into the container. It will be hard to drain just a little bit of oil to get your oil levels back to normal. So, you’re probably better off draining all the oil and then adding new oil to the engine. Make sure you add the oil slowly and keep checking to make sure you don’t go over the required amount.
