You should find out the reason the oil is overfull. If the oil is contaminated with water then you may have a head gasket blown. If the oil is contaminated with fuel then you may have a fuel injection system flooding the engine. Either way have the oil and filter replaced (since it may be contaminated) and the correct amount of oil put in. When you have this service done, have them check why the oil was overfilled in the first place.

If the oil level is a little above the full mark, that shouldn`t cause problems. If it`s overfilled by half a quart or more, or foam shows on the dipstick, the best fix is to have the oil drained and refilled to the proper level.
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
Use your socket wrench to start loosening the oil plug. You want the overfill oil to start trickling out slowly. Let it drip until you think you have drained enough oil, then tighten it back up. If you loosen the oil plug too far too fast, you run the risk of actually taking it out.
If you overfill your oil to the point that the crankshaft hit the oil as it spins inside the engine it will cause the oil to get entrained with air and the tiny air bubbles will reduce the ability of the oil to lubricate. That being said a half quart or less shouldn`t raise the level enough for that th be a problem.
“Too much oil can damage your engine. If you notice an overfill of oil, the excess should be drained out of the engine. Therefore, we recommend checking your dipstick regularly.”
After an oil change, do not immediately top up to the specified oil level. Instead just fill to the minimum mark. Then run the engine until the oil pressure has built up. After switching off the engine, wait a couple of minutes for the engine oil to flow back into the oil pan.
A: Overfilling an engine with oil can put additional pressure on seals and, over time, can cause an oil leak.
A conventional car can last for 200,000 miles. Some well-maintained car models will reach 300,000 or more miles total. The average passenger car age is currently around 12 years in the United States. Choosing a well-built make and model can help extend your car`s longevity.
When the oil is whipped into a froth from overfilling, very little oil gets into the motor. This oil then gets overheated and starts to break down much like the oil in an underfilled reservoir. With very little oil filtering through the engine, everything starts to overheat.
A: The dealer and manufacturer are correct that adding some oil between oil changes in a modern engine is normal, especially considering the oil is very thin — 5w-20 weight oil — and the longer 6,000-mile oil change interval.
Overfilling the oil should not cause a head gasket to give up. However, it could force some oil into the engine upper end and cause smoke. This can also come across as white in color.
When engine oil is fresh—as it is when your car is brand new or after every oil change—the oil life indicator will read 100%. From this point on, as dirt begins to accumulate during normal daily driving, the percentage begins to decline.
But never wait for the oil to reach that level. As mentioned above, change the vehicle`s oil when the oil life indicator is between 15% and 40%. Sooner or later, your engine will start showing signs of damage that could be disastrous. Properly grease your engine.
Insert the dipstick into the tube slowly and push it all the way down. Now withdraw it and look closely at the tip, which should have oil on it. If the level of the oil is between the two lines, your vehicle has enough oil. If it`s at the low mark or below, it`s time to add a quart.
Checking Your Oil Level
Many car companies will put it in print, in your owner`s manual or maintenance guide, that usage of a quart of oil every 1000 miles is in the acceptable range.
To get an idea of how much oil you need; the gap between the marks on the dipstick usually represents around 1 litre of oil, so you know that if your oil mark was at the minimum, you need around a litre to top it up. If it`s only halfway down, you probably need around half a litre.
How much oil is too much on dipstick? Any more than about an eight of an inch above the full mark. If it read more than an eight of an inch the excess oil could cause damage to your engine seals.
