Is Motor Oil and Engine Oil the Same? here’s why

Do you ever stop in your tracks when you see a car with engine oil and motor oil in the same spot? It looks like they’re both meant for the engine. But is this the case? And is it safe to use engine oil and motor oil together? 

Motor oil and engine oil are the same types of lubricants as both are labeled according to their intended use. Motor Oils are used for conducting electricity within an object so they won’t vaporize easily at high temperatures. Engine Oil is designed specifically by race teams who want maximum power.

What is motor oil, and what is engine oil?

Motor oilOpens in a new tab. (also called motor fuel oil or engine oil) is a petroleum-based fluid that lubricates the parts of an automobile’s engine. If your car has an engine, you might have motor oil and motor fuel oil in your garage.

Engine oil (also called petrol or diesel) is a petroleum-based fluid with a higher boiling point than motor oil and is designed to be used in engines to lubricate the parts of the vehicle.

Finally, there are two types of engine oils: synthetic and mineral. Synthetic oilsOpens in a new tab. are formulated specifically for use on engines. Mineral oils are made from crude petroleum and can change over time depending on the vehicle’s type of operation. They should not be stored together as they would cause damage to each other.

What are the different purposes of motor oil and engine oil?

Each type of lubricant has a different purpose. Motor oil is used to keep your engine running smooth and sound. Engine oil lubricates your engine and creates a good fuel mixture. It would help if you never used both types of lubricants simultaneously.

So, why do you need motor oil when you have engine oil? According to the United States Department of Energy, 80 percent of tanks in the US are filled with oil. This means that if you don’t have an engine charging system, you may be wasting money on maintenance.

If you don’t change your engine’s oil regularly, you may waste money on maintenance or end up with an inefficient vehicle.

Is engine oil the same as getting an oil change?

Engine oil and motor oil are the same types of lubricants. They both work to enhance your engine’s performance, but they also have different purposes. Just because an engine needs oil doesn’t mean you need to use engine oil and motor oil together.

Engine oils should be changed every 4,000 miles (6,000 kilometers). You should only use engine oil for a short period each time you turn on the car: 2-3 minutes at most. It will take about half a gallon (1 liter) of fuel to run the engine properly, with 50 percent of that being used for lubrication.

If you’re in an area where it rains a lot, you might have an issue getting the oil changed as soon as possible one reason is that when it rains hard, water can seep into your engine and ruin it. Attempts to change your oil may not result in good results unless you know how to do it right.

How do you know if your engine oil is bad?

Engine oil is a very important and necessary lubricant for your engine. But engine oil can also be dangerous. It would help if you never used it with your car’s fluids because those fluids can cause damage to the engine.

So what are the signs that you need to replace the engine oil?

The first sign of an engine problem is a check engine light. An indicator on your dashboard will tell you whether or not your car needs an oil change. 

If it does, then you’re in luck because this probably means that there’s something wrong with your motor. If your check engine light comes on when you’re driving, then the chances are that something is wrong with the motor itself. 

How long can I go without an oil change?

Many drivers get an oil change every 10,000 to 15,000 miles or so. Your engine will last most of that time without an oil change. But once you start seeing signs of wear and tear on your engine, it’s time to upgrade to a new one.

Every year, the American Society of Engine Oil Engineers (ASE) publishes recommended recommendations for how long you should leave your engine in the air conditioner before getting a new one.

The ASE recommends going more than 20,000 miles before getting another oil change.

Can I mix engine oil?

The life expectancy of your engine depends on the type of motor oil you use. It’s important to choose an engine oil that can be mixed with your existing motor oil so that you can extend the life of your car.

When mixing an engine oil, it’s important to follow these three steps:

1.) Know what type of engine oil you are leaving in your car after buying a new one (if necessary).

2.) Nail down a mix ratio for each type of engine oil.

3.) When boiling down the amount of fuel and water added to your new motor oil, do not forget to include any additives that may have been added to the original fuel and water mixture.

Can I top up engine oil when the engine is hot?

You can put oil in your car when the engine is hot. Check for leaks and replace any you find after adding, but it’s safe to do so as long as all other precautions are taken with a few exceptions. Never add more than 1/4 of an inch past the “max” line on dipsticks; be sure not to pour at high speeds since this could cause overflow accidents sending liquid spilling everywhere.

Be very careful to make sure nothing blocks ventilation holes around hoods or trunks before closing them completely. Oil will spill out quickly once poured onto the ground because these areas have no protection against harmful rays from sunlight.

The reason to buy new motor oil is that it has a higher viscosity when it’s cold and dries out at a lower temperature, which means that the motor will run smoother at higher temperatures – even if your car doesn’t get driven very often.

When you purchase motor oil for your car, make sure that it comes in a bottle with a lid. You don’t want the open lid to let any air into the bottle, so it should be sealed tightly with a rubber seal around the bottle’s neck.

Engine oil Grades


The OW-20 grade is a synthetic blend of oil designed to offer superior protection against wear and tear, oxidation, corrosion, foaming or sludging, and viscosity retention. This type of oil should be used in vehicles that require an API SN motor oil.

SAE 0W-40 Motor Oil

The SAE 0W-40 grade is a synthetic motor oil that offers superior protection against wear and tears, oxidation, corrosion, foaming or sludging, and viscosity retention. This type of engine oil should be used in vehicles that require an API SNX motor oil.

SAE 15W-40 Motor Oil

The SAE 15W-40 grade is a synthetic diesel engine oil that offers superior protection against wear and tears, oxidation, corrosion, foaming or sludging, and viscosity retention. This type of motor oil should be used in vehicles that require an API SNX motor oil.

SAE 20W-50 Motor Oil

This grade of engine oil is known as a mineral-based lubricant which means it can offer reduced friction levels for better performance but does not provide as much resistance to heat as other types do. 

The benefits of using this type are lower emissions and extended drain intervals, so your vehicle will last longer without changing the oil frequently. It also has excellent stability against high-temperature degradation during use, making it one of the best options for vehicles frequently used in stop-and-go traffic.


Motor oil grades can be confusing to understand, but it is important to use the correct type of oil for your vehicle to protect the engine from damage. Choosing an appropriate grade of motor oil will help keep your car running smoothly and extend its life.
