Metal shavings are referred to as small metal particles in the engine oil. These are also called metal debris, flakes, and chippings. The continuous friction of oil in the engine moving parts make them contaminated with debris, for example, metal shavings. 

Mostly, you’ll find metal shavings in oil filter, crankcase and dipstick. 

Metal in oil isn’t an uncommon activity; instead some portion of it in oil is fairly common. Although some portion of metal in oil is reasonable, it may shorten the engine life or demand expensive repairs. 

What Causes Metal Shavings In The Engine? 

Our vehicle comes with multiple moving parts. Almost all of those are metal. Sometimes, the oil starts breaking down and can’t ensure proper lubrication. Therefore, it causes metal to start grinding each other and results in metal in oil. 

For example, suppose an engine runs at 2500 RPM, all the installed metal parts start rubbing against each other. Because of the shortage of proper lubricant, the heat and friction between metal parts create small metal shaving.

How Much Metal In Oil Is Normal?

what causes metal shavings in engine

After passing a long period in the engine, engine oil may gather various metal flakes. Hope that you know the oil filter helps to catch metal flakes. But, if any problem occurs in that part, the filter can’t effectively catch those metal flakes. 

Typically, those small items could be steel from the crankshaft, bearing backing materials, or other components of your engine. 

We already mentioned that metal’s existence in oil isn’t unusual; instead, it’s pretty normal after a long period. You may have a question like how much distance or time is liable to gather metal in the oil. 

Against that question, we found that the average mileage for showing metals in oil is 10,000 miles. But, before passing 5000 miles, noticing metal flakes isn’t normal. You need to be alarmed by that. So, the question is, “how much metal in oil filter is normal.”

On the contrary, if you notice a good amount of metal in the oil filter, for example, 20 to 40 metal particles, you need to immediately change your engine oil and oil filter. Then, you need to inspect the filter within 10 hours to see whether any improvement is noticeable. 

You can’t easily detect those insignificant items with your bare human eye. You need to use a magnet to check. 

Finally, you should take the metal shaving-related issue seriously. If you don’t take it seriously, your engine can’t perform properly. Over time, it may lead to engine damage. 

Different Types of Metal Shaving

In the following discussion, we notify you of different metal particles in engine oil.

Iron: You can easily test iron-type metal shaving using a magnet. Those items typically come from the rotating parts of your vehicle, for example, crankshaft, camshaft, or other parts of the valve train. 

Bronze/Brass/Copper: This type of metal shaving is the part of camshaft bearings, worn bearing or bushing, turbo thrust bearings, crankshaft, wrist pin bearing. 

Aluminum: Aluminum-type metal shaving typically comes from the bearing’s surface wear. It occurs because the aluminum caps or overhead camshaft holds the camshaft in place. 

Molybdenum/chromium: This item comes from the piston rings and the wear of pistons.

What Do Metal Shavings In Oil Mean?

Metal shavings in oil mean the oil is contaminated, and the contaminated oil means your engine can’t get enough lubricant. The presence of access metal shavings in oil creates snowball effects. 

[Snowball effects: More metal shavings= More dirtier oil]

Due to the contaminated oil, friction occurs in moving parts too often, making oil even more dirtier and less lubricant. 

If the oil becomes less lubricant and can’t provide enough lubrication on those moving parts, then the details will grind into themselves. Hence, those parts may wear out quickly. 

Wearing out those items is normal. But, those items need to be filtered out using an oil filter. If any problem occurs in the oil filter, then the oil filter can’t catch all those metal flakes.

The Mobil 1 M1-110A could be one of the best oil filters, especially for those who want an extended performance filtering option.

Including parts of engine bearings are small-end and camshaft bearings, main, connecting rod. That bearing may be tri-metal or bi-metal structures. 

Usually, a technician uses a magnet to ensure that the engine bearing causes the problem. The magnetic shaving shows the problem is associated with the crankshaft, bearing backing materials, or other engine components. 

How To Check for Metal Shavings In Oil?

You already know metal shaving can’t detect your naked eyes. But, when you clump those shaves together using a magnet, you can easily notice. You can relate those with silvery sludge. You will find a magnet in some oil drain plugs. 

But, most offer nothing like that. Don’t worry; if your oil drain plug comes with no magnet, then analyze the oil. Hence you can tell the metal amount and the types of metal in your oil. 

The 2nd checking method is you can open the filter and then pour that oil into a pan.

How Do You Know Your Oil Has Metal Shavings?

Some symptoms show your oil has metal shaving. You can keep your vehicle from serious benign damage using those early indications. So, let’s see those in the following.

  • Noises (Ticking): Metal shaving retard the smooth oil flowing in the desired places. Due to a lack of proper engine oil, the engine can’t get enough lubricant, resulting in a ticking sound.  
  • Rough idles: Improper lubrication may lead to friction between different engine parts. Therefore, your engine may shake or vibrate excessively during idling. 
  • Knocking sound in the engine: If you don’t take proper action, debris and metal shaving buildup in oil may deteriorate engine parts. When fuels burn become uneven in cylinders, then it causes knocking. Therefore, ignited fuel-consuming air produces a clunking sound. 
  • Exhaust fumes become white: If you notice white exhaust fumes, then take it seriously. Because the white exhaust fumes show, the cylinders may get oil. If you find anything like that, then bring your car to the repair shop asap.
  • Poor driving experience: If you ensure proper maintenance of your car, it will give you a great driving experience. But, metal shaving in the oil will create various problems, hence threatening your vehicle’s engine’s performance and health, resulting in a poor driving experience. 

Also, the engine warning light shows the symptom of metal shaving in the oil. If you see the light come on, then take the sign seriously. However, you will see the oil change or oil pressure indicator in some old-model cars. 

What To Do If There Is Metal In Your Oil?

Varnish deposits or carbon deposits are indications of the high-temperature source. You can see oil’s tiny metallic particles using the bright sunlight. 

For that, you need to manage the oil sample and bring it to the sunlight. Suppose there lie any tiny particles, for example, microscopic particles of brass. The bright sunlight will help to reflect those particles.

Can you drive a car with metal shavings in oil?
