How Often Should You Add Motor Oil

The most important maintenance for your car is the timely changing of the motor oil because the engine is made of a complex piece of machinery that comprises of different moving parts. The engine oil helps keep them lubricated while preventing corrosion and wear and tear, and keeps the engine clean of debris.

When the oil has been used for a while, it will become dirty due to dirt, dust, and debris accumulating. The dirty motor can be hazardous as it fails to do its job correctly and may add to the risk of the cost of damages down the road. To keep your engine running smoothly and at optimal capacity, it is crucial to have oil replaced at the appropriate time frames as instructed by the owner’s manual requirements.

What is Motor Oil?

Motor oil or engine oil refers to the various substances comprising base oils enhanced with different additives, especially the anti-wear additives, detergents, dispersants, and for multi-grade oils, viscosity index improvers. However, motor oil was a mixture of base oil and additives often used to lubricate engine parts, thus reducing friction, cleaning, cooling, and protecting the engine.

What is Oil Viscosity

When it comes to oil the term viscosity is often used and it simply refers to the rate at which oil pours easily at a specific temperature rating. It is found that the thinner the oil the easier it tends to flow when exposed to a lower temperature and on the other hand thicker oils happen to have a higher viscosity.

When the weather is cold the oils that are thin often reduce friction which helps the engines to ignite faster. In countries with higher temperature thick oils are mostly used because it helps maintain the pressure of the oil and film strength thus supporting heavier loads.

When comes to the term viscosity index is used often used to measure the ability of the oil to resist the changes in the viscosity and the temperature fluctuation. For oils that are multi-grade, they are formulated with the viscosity index improvers that use polymer additives to maintain a consistent viscosity at a wide range of temperatures thus effective in protecting the engine from wear and tear.

When the viscosity index of the oil is high it easily retains its viscosity over a wide range of temperatures, even though the viscosity index improver will break down over a period as the oil ages, the regular changing of oil helps to prevent this aging process in your engine.

In general, there are various types of motor oil which will be discussed in the following subhead:

Types Of Motor Oil

Though all engine or motor oil serves the same purpose, there are different types of motor oil, ranging from synthetic, semi-synthetic, or conventional oil and mineral motor oil.

  • Synthetic Oil: This motor oil is engineered chemically to create a higher-performing oil than conventional oil and works better in high and low-temperature extremes.
  • Synthetic Blend Motor Oil: The blend motor oil is a mixture of synthetic and conventional base oils, thus providing higher resistance to oxidation and better performance in low temperatures. It is a popular choice amongst drivers of pickup trucks and SUVs because it allows for additional protection for cars carrying heavier loads. In terms of the cost, it is significantly less than synthetic oil.
  • High-Mileage Motor Oil: This type of motor oil is designed for newer cars, and it is enhanced with unique additives to minimize oil burn-off and oil leaks that may occur as the older engine ages. This motor oil is designed for newer or late-model vehicles running a distance of more than 75,000 miles. 
  • Conventional Motor Oil: Lastly, Conventional motor oil is available in a broad range of viscosity grades and quality levels. It’s appropriate for cars with simple engine designs and drivers with conservative driving styles. The Conventional motor oil meets the criteria for API specs that is recommended by the engine manufacturer but this type of oil does not have the added performance found in the synthetic type of motor oils. 

The benefits of engine/motor oil will be discussed below.

Benefits of Motor Oil

The Motor oil provides lubrication to the moving parts of an engine, which aids in avoiding damage and keeps your engine running smoothly. The following are the benefits of motor oil;

Keeps engines safe from damage: 

One of the essential benefits of motor oil is to stop unnecessary repair costs. Without lubrication, machines can become highly damaged as heat and friction destroy engine parts.

Ensures an extended engine lifespan: 

Using cleaning the engine from sludge deposits and reducing friction between parts, motor oil prevents the engine from bottlenecking. The motor oil ensures machine-driven parts last longer and corrodes slower, helping the engine perform better and have an improved lifecycle.

Decreases fuel consumption and CO2 emissions: 

Motor oil plays a significant role in an engine by reducing fuel consumption, and emissions of gases from vehicles are further decreased. If there is little oil, the resulting friction lowers its efficiency, increasing fuel consumption which can lead to an unexpected breakdown.

Keep your motor clean:

 When oil circulates into your motor and other moving parts, the dirt along with other contaminants will begin to build up inside of your engine; and you are not regulating your oil change within the appropriate times as you should, the sludge will quickly build up inside the motor. Also, note that people who live in drier or dustier regions will have even far more contaminants making their way through their engines. However, changing your motor oil on a timely basis is sure to get rid of dirt and debris from your motor before doing any harm.

Long motor life:

Oil is the life wire of your car or any engine machine. The oil lubricates and helps to protect your motor and numerous indispensable components from wear and damage by ensuring that you have your oil changed in agreement with your owner’s manual requirements. In addition, a regular prearranged oil change is necessary to ensure driving your car for many years.

Protect other engine parts: 

Since vehicles are known for numerous vital components. The motor oil makes your car operate optimally and protects other engine parts such as the crankshaft, pistons, rings, and collecting rods. These rods regulate the pistons inside the motor’s cylinders. 

Improving engine performance: 

Over time, oil breaks down because of heat exposure leading to it losing its viscosity and capacity to lubricate the engine cylinder walls. The darker the oil is, the more challenging it is to travel precisely where required in the car and when sludge starts to develop in areas obstructing the flow to components that require lubrication. An additional purpose of oil is to pull heat from various motor areas.

Motor oil performs a similar function in vehicles and any other machine that uses fat for optimal performance. In general, there are five main functions of motor oil which are:

Why quality motor Oil is Important

It’s always best to consult the manufacturer’s manual when making a choice of oil for your car’s engine; always remember Just remember to check for the API seals so you know you’re assured of quality oil. And even though, over time, there has been an endless debate over which brand of motor oil is the best, as long as you know how to spot a quality motor oil and you ensure to change it at the recommended intervals, your car’s engine will likely run for a long time.

In today’s society, motor oils are categorized based on the rating system, which the Society of Automotive Engineers develops (SAE), which rates oils by viscosity. When the need the oil that can perform at various ranges of temperatures, you should opt for the multi-grade viscosity motor oil. The “0W-20,” where “0” is an example of the SAE viscosity grade oil where “0” symbolizes the cold-temperature viscosity rating, the “W” is used to r for winter, and the 20 is the operating temperature viscosity rating.

However, motor oils are branded based on a grading system by the Society of Automotive Engineers, which rates oils by viscosity. When you are trying to choose the motor oil with the capacity to achieve at a wide variety of temperatures, you can select a multigrade viscosity motor oil. The “0W-20,” where “0” an SAE viscosity grade represents the cold-temperature viscosity rating, the “W” is used to represent winter, and the 20 is the operating temperature viscosity rating. In addition, motor oil provides you with a lot of benefits not just for your cars or trucks but for engines that require lubrication for their smooth running.

Reasons to add Motor Oil

  • Engine/motor oil helps in reducing friction. The primary importance of motor oil is to lubricate the engine parts, which are constantly subject to conflict. They tend to reduce friction and wear, reducing maintenance costs drastically.
  • Engine/motor oil help in removing impurities. The cleaning ability of motor oils is vital to the health of the engine. When the engine function, there is often a build-up of Microscopic deposits that consist of dust or combustion residue, and in the absence of engine oil, this dirt would clog the engine, thus decreasing its performance as the flow of motor oil continuously carries these impurities to the oil filter, where they are trapped. 
  • Engine/motor oil acts as a coolant. Yes, this is true because, during the combustion process, heat from combustion and friction between moving parts cause the engine temperatures to rise, but the Motor oil amazingly o traps, transfers, and releases this heat through the lubrication circuit, supplementing the engine coolant, which can only cool certain parts of the engine. 
  • Engine/motor oil acts as a gap filler.
  • Engine/motor oil inhibits rust and corrosion. Engine oil consists of rust and corrosion inhibitors that protect against regular wear and tear.

Frequently Asked Questions on Motor Oil

Q1-When should I get my following oil change?

 For a new vehicle and you are usually gone 20 minutes or more, ensure to increase the time between your oil changes. However, if your car is older, it is best to stick with the manufacturer’s recommended maintenance schedule.

Q2- Is motor oil the same as engine oil?

Motor oil or engine oil usually confuses users, but they are both the same in the market. It refers to substances with a base oil that’s laced with additives (anti-wear additives, dispersants, and detergents, to name a few).

Q3- What is synthetic oil?

A- They are referred to as oil that has undergone some chemically engineering processes. Compared to the conventional type of oils the molecules of the synthetic oil are usually more unified in shape and possess lesser impurities. This type of oil also has a higher oxidation resistance and performs much better in environments with extremely high and low temperatures than conventional motor oil made from crude.

Q4- What happens when your car runs out of oil?

Whenever your engine runs out of oil, moving parts will begin to rub against each other since they don’t have lubrication. When this happens, the engine will seize up and eventually fail, which causes damage that is extremely difficult to reverse. Always ensure to check your oil level regularly and change your oil often.

Q5- What does oil do in a car?

It is designed to lubricate engine parts, reduce friction, clean, cool and protect the engine.
