Engine oil- complete details.

What Does Oil Do in a Car?
Motor oil was historically a simple mixture of base oil and additives, Oil in a car helps maintain engine efficiency by acting as a lubricant. This reduces friction between moving parts and prevents wear and tear. It also helps prevent acid build-up by neutralizing harmful acids formed during combustion, which protects engine components from potential damage.
Additionally, oil cleans and protects turbos and modern engine components by suspending dirt and debris. Corrosion inhibitors present in the oil further safeguard the engine by forming a protective layer on metal surfaces, reducing the risk of rust and corrosion.
Why does a car need oil?
Why does a car need oil? A car needs oil primarily for lubrication, cooling, cleaning and protecting engine components. Engine oil reduces friction between moving parts, preventing wear and tear that could lead to costly damage.
By minimizing friction, oil helps maintain the smooth and efficient operation of the engine. Additionally, oil acts as a coolant, dissipating heat generated by the engine and preventing overheating. It also plays a crucial role in cleaning by carrying away dirt, debris and microscopic metal particles, which are then trapped in the oil filter.
Regular oil changes are essential for maintaining engine health and performance, as old or dirty oil loses its effectiveness and can lead to increased friction, overheating and buildup of harmful deposits.
Is Engine Oil the Same as Motor Oil?
You might have heard engine oil referred to as motor oil or vice versa. Both products are the same in the market and simply refer to any substance with a base oil that’s laced with additives (anti-wear additives, dispersants and detergents, to name a few).

Motor oil vs. engine oil
Motor oil and engine oil are terms often used interchangeably to describe the same essential lubricant designed for the optimal performance and longevity of an internal combustion engine.
Despite the different names, both motor oil and engine oil serve identical primary functions:

• Lubricating moving parts to reduce friction and wear
• Cooling the engine
• Cleaning by trapping contaminants
• Protecting engine components from corrosion and rust

There are various types of motor and engine oils, including conventional, synthetic and synthetic blends, each offering distinct benefits for different engine requirements.
Is engine oil the same as motor oil? Both motor oil and engine oil are essentially the same thing, with a similar function.
Oil Viscosity Explained
When talking about motor oil, you’ll often hear the term “viscosity” being used. Essentially, oil viscosity refers to how easily oil pours at a specific temperature. Thinner oils flow easier at lower temperatures and have a lower viscosity, whereas thicker oils have a higher viscosity.
In cold weather, thin oils reduce friction and help engines to start quicker. In higher temperatures, thick oils maintain oil pressure and film strength and support heavier loads.
The viscosity index measures oil’s ability to resist changes in viscosity as temperature changes. Most multi-grade motor oils are formulated with viscosity index improvers, which use polymer additives to help maintain consistent oil viscosity over a wide range of temperatures—protecting engine parts from wear.
An oil with a higher viscosity index number can better retain its viscosity over a broader temperature range. However, these viscosity index improvers will break down over time as the oil ages. Changing your oil regularly will help prevent this.
What Is Synthetic Oil?
Engine oil has changed significantly over time. When it was first introduced in the 1800s, manufacturers used their own fuel and lubrication techniques, which led to many inconsistencies. The usage of animal fat and vegetable oil evolved into the use of motor oil made from crude. Later came the invention of synthetic oil.
Synthetic motor oil is oil that has gone through a chemically engineered process. When compared with conventional oil molecules, synthetic oil molecules are more uniform in shape and have fewer impurities. Typically, synthetic oil will have higher oxidation resistance and perform better in extreme high and low temperatures than conventional motor oil made from crude.
When fully formulated, motor oil is designed to serve a variety of different functions, including:

• Separating and lubricating moving parts
• Reducing engine wear
• Helping to prevent deposits from forming on internal engine components
• Removing and suspending dirt and contaminants in the oil until these contaminants can be removed at the next oil change
• Cooling engine parts
• Maintaining engine fuel efficiency and performance
• Providing protection across a wide range of temperatures.
• Functioning as hydraulics in variable valve timing
• Helping protect the emissions system. More assist cantact us Dhanya auto care center

Is Synthetic Oil Made From Natural Gas Better?
Motor oil grades
Today’s motor oils are categorized based on a rating system developed by SAE, which rates oils by viscosity.
If you’re looking for an oil that can perform at a wide range of temperatures, you’ll want to opt for a multi-grade viscosity motor oil. An example of an SAE viscosity grade is 0W-20. The “0” symbolizes the cold temperature viscosity rating, the “W” stands for winter, and the 20 is the operating temperature viscosity rating.
As a rule of thumb, always look at your vehicle’s owner’s manual to determine the correct motor oil SAE grade for your specific engine.
Another symbol that commonly appears on motor oils is the API “donut.” API stands for the American Petroleum Institute, which offers a stamp of approval to help customers find engine oils that meet the minimum standards set by engine and vehicle manufacturers.
This symbol has three parts: the top half of the circle indicates the API service rating, the center of the circle displays the SAE viscosity and the lower half of the circle tells you the oil’s energy-conserving properties
Other Types of Motor Oil
In addition to synthetic motor oil, there are three other common verities of oil.

• Synthetic Blend Motor Oil: This type of oil uses a mixture of synthetic and conventional base oils to provide higher resistance to oxidation and better performance in low temperatures.
• High-Mileage Motor Oil: Formulated with unique additives, high-mileage motor oil helps to reduce oil burn-off and prevent oil leaks that can occur in older engines. This oil is designed for newer or late model vehicles with more than 75,000 miles.
• Conventional Motor Oil: Lastly, conventional motor oil comes in a variety of viscosity grades and quality levels. It meets the basic API specs recommended by your engine manufacturer but does not have the added performance found in synthetic motor oils.

The Importance of Changing Oil
Motor oil provides lubrication to the many moving parts of an engine, which helps to avoid damage and keep your engine running smoothly.
Each time your engine runs, by-products from combustion are collected in your engine oil. If contaminants build up beyond the capacity of the oil, they accumulate and create deposits, sludge and wear in the engine.
If the oil is not changed regularly, these contaminants can have a negative impact on your vehicle’s overall performance and efficiency. In addition to changing your oil when recommended, it’s important to keep up with regular vehicle maintenance and use a quality motor oil, such as one from Pennzoil.
So how often should you change your oil? Typically, it’s best to change your vehicle’s oil every 3,000 to 5,000 miles or your manufacturer’s recommendation. However, this is all dependent on factors such as your vehicle’s age, driving conditions and the type of oil you use.
Fortunately, many modern-day cars have engine oil indicators and will provide you with a warning signal on your dashboard when your oil is low or when to change the oil. Many dealerships or service centers will also put a sticker on your window with the date you will need your next oil change.
What Happens When Your Car Runs Out of Oil?
If your engine runs out of oil, parts will start to grind together since they don’t have lubrication, and the engine will seize up and eventually stall. This causes damage that is extremely difficult, if not impossible, to reverse. This is why it’s so important to check your oil level regularly and change your oil often!
In addition to your vehicle’s check engine light on your dashboard (if it has one), there are a few other signs to look out for that can indicate it’s time for an oil change.

• Engine noise: When motor oil is doing its job, it will lubricate the parts in your engine and as a result, keep the engine quiet. However, if your oil level is low or has completely run out, you may start to hear knocking or rumbling sounds. If this occurs, take your car in for an oil change immediately.
• Smelling oil inside the car: Smelling oil inside your car is a sign that you may have an oil leak. If you ever smell exhaust fumes or gas, your vehicle may be overheating. In either case, you’ll want to take your car in for a maintenance check as soon as possible.
• Exhaust smoke: It’s normal for your car’s tailpipe to emit translucent vapor. But if you ever notice that this turns to smoke, you may have an oil leak or faulty engine parts.
• High mileage: As stated previously, most vehicles require an oil change every 3,000 to 5,000 miles, or roughly every three to six months. If you put a lot of miles on your car one month, you may want to take your car in for an oil change a bit sooner to avoid any issues. This is especially the case if you have an older vehicle.
• Dark-colored oil: Clean oil is translucent with an amber hue. Over time, it will turn to a darker color due to collected contaminants and deposits. If you’re checking your oil and notice that it’s turning a dark color, this is a key sign it may be time for an oil change. More assist cantact us Dhanya auto care center
