Engine Oil

For Preventing Motor Oil Deposits

You can clean your car’s exterior as many times as you want, but almost every time, there will be some gunk or grime that makes it difficult to think about its origins. You clean your car and go on a relaxing drive to thank yourself for all the hard work. Do you ever stop to think about the inside of your car? Not just on the exterior but also inside.

Apart from pride, there are other reasons to keep your engine clean. An engine clogged with dirt and motor oil will cause it to lose horsepower and make it less efficient. Motor oil can cause engine blockages, but it is also part of the engine’s job to remove and prevent this harmful stuff. We’ll show you how to get the best out of your motor oil without wasting too much.


  1. Learn How Motor Oil Deposits are Formed
  2. Do Not Fear Paraffinic Wax
  3. Do Not Assume That Using Synthetic Oil Will Prevent Buildup
  4. Oil Change at the Correct Interval
  5. Please follow the manufacturer’s recommendations

How are Motor Oil Deposits Formed?

Understanding how and why motor oils get stuck in your car’s engines will help you better understand the different oil options available and how to choose the right oil for you.

Castrol, an oil marketing company, says the most common causes of oil-related engine deposits include:

  • Excessive idle and frequent short trips can prevent oil from fully cycling.
  • Oil can contain environmental contaminants (such as dirt and other debris).
  • Condensation can cause oil to become contaminated with moisture.
  • Hot spots are hot areas that bake oil and clump onto the engine.

There are many engine blockages, and not all are caused by oil. Even if the cause of the buildup is another problem, such as condensation or leaky seals, for instance, oil can still contribute to the problem. Because it circulates, the oil distributes contaminants and other fluids throughout the engine.

The buildup is partially and unburned fuel, metal fragments and dirt from engine component wear, and any other debris that finds its way into your car’s engines. Partially combusted fuel can escape from seals and piston rings that are worn. This causes buildup. These deposits travel through the oil and settle somewhere. This can restrict or block the oil flow, which causes engine wear. They become thick and gummy as they form deposits and harden when they settle in the engine. The engine heat will quickly melt the deposits, and once they have formed, the oil will not flow around them anymore. It is not difficult to get rid of the hardened grime that builds up quickly. The main targets for deposits are the fuel injectors and piston rings, which can cause problems with smooth, efficient engine operation.

Oil is lubricating and helps prevent deposits. It also cleans the engine by capturing and dissolving any sediment.

Don’t Fear Paraffinic Waxes.

There are many myths surrounding specific types of oil, which is why people are confused about oil deposit causes. Paraffinic oils, which contain natural waxes, are the leading cause of oil deposits. Let’s look at the composition of natural oils to see if this belief is true.

Crude-based oil is produced in an oil refinery using natural resources. Crude oil is the base for all oil-based products. The crude oil is separated into various components at the refinery. Crude oil is a valuable natural resource that can never be replaced.

Paraffinic, or paraffin-based crude oil, is a type. Paraffin-based crude oil has a reputation for causing deposits in the engine. This is because wax, one of its main components, is used to make motor oils. Although the wax is not beneficial to motor oils, it can be used in other products.

However, there is still some wax left. It’s too costly and inefficient to continue repurifying oil to remove any remaining paraffin. It’s not worth the effort for a mass-market product such as motor oil that is relatively cheap. The motor oil made from paraffin will have very little wax. Although small amounts of residue can form crystals at low temperatures, this is not the dangerous greasy coating much fear.

You might be curious about the alternatives to crude oil. You have synthetic oil. Although it sounds cleaner and more scientific than crude oil, it may not solve all your problems.

Do not assume that synthetic oil will prevent buildup

We’ve seen that consumers have many options when it comes to oil. As you can see, minerals or synthetic are two of the most important decisions.

Crude oils derived from oil from the earth’s natural resources may contain sulfur or other harmful contaminants. These pollutants are often removed during oil refining, but it is impossible to purify mineral-based oils completely. It is too costly and impractical to invest in machinery to filter the oil to its pure form. As we have already mentioned, motor oil deposits are caused by remaining contaminants.

Although synthetic oils are more expensive than those derived from minerals, they offer some benefits. They aren’t derived from fossil fuels and don’t deplete other non-renewable resources. They can also be customized-blended by chemists to meet any automotive need, no matter how complex. If you’re considering investing in synthetic oils, consider the benefits and costs. Although lab-engineered oil is cleaner than crude-based oil, it is not perfect.

The synthetic oil industry wants you to believe their products are the miracle cure for every engine. Although synthetics offer many benefits over traditional mineral oil, it is tempting to believe that you can afford the higher price but still get a longer oil change interval. Mike Allen from Popular Mechanics says it’s a bad idea. Although your engine may be healthier when using synthetic oil, gunk can still build up and cause damage. Keep to the recommended interval of change, usually between 3,000 and 5,000 miles (4.828 to 8.047 kilometres).

Change your oil at the proper interval

It’s not worth taking the chance of saving some money on an oil change. 

The conventional wisdom is that your oil should be changed every 3 months or 3,000 km, whichever comes first. This is not always true. Some cars and oils can last longer, while others, such as race cars, should be changed more often. Follow the manufacturer’s guidelines for the correct interval.

Although it is often ignored, the “whichever comes first” rule is true. Why is it so important to change your oil regularly even if the car hasn’t been driven yet?

A condition known as oil viscosity break is where motor oil’s structure becomes damaged while it does its job. The oil is circulated through the engine and is masked between the gears and other moving parts. While the oil prevents metal-to-metal contact is extremely dangerous, it absorbs the bulk of the moving metal. This causes oil to lose its thickness or viscosity quickly, one of its main characteristics. Oils are classified by viscosity, which is another way to describe the oil’s “weight”. This refers to the number of oils you buy based on your manufacturer’s recommendation.

The oil that has begun to degrade is less capable of lubricating an engine. Oil’s many additives and detergents can also lose their potency or evaporate over time as its lubricating capabilities decrease, making it less capable of cleaning the engine’s surfaces and trapping contaminant particles. It also has a lower ability to condition the engine seals and keep it in top performance. It’s not worth the risk to save a few dollars on an oil change. Why wait?
