1. Liberty Motor Oil

You must have the best motor oil, and you have to pick one with efficiency and good quality. But the liberty motor oil does nothing of the following. Liberty oil claims too many positive results and advantages. 

However, they are not accurate with their words. They state many benefits of purchasing and using their motor oil, but their motor oil is too low quality. Their motor oil has a very low percentage of additives. 

And one thing you should know is that good motor oil must have a good amount of additives because additives are responsible for providing good lubrication. Good motor oil will keep your engine running smoothly. With good motor oil, you will also have minor corrosion in your vehicle’s engine and its components. 

You will also need the required and right amount of motor oil that has the proper viscosity level. Choosing liberty motor oil must not be in your choices. You will not have any advantages on your part.

2. Quaker State Q

If you want your vehicle to perform at its best performance, you should not try Quaker State Q. If you choose Quaker State Q, you will find out that their motor oil diffuses very easily and quickly. If your oil diffuses very quickly and easily, it means that your motor oil has high volatility. 

It also means that it has very low quality. If you choose this motor oil, you will have more repair expenses and more maintenance because your vehicle will suffer more in the long run. If you keep on using Quaker Stat Q on your vehicle’s engine, it will do significant damage to your car. 

This is because their motor oil does not have the proper lubrication and quality that motor oil should possess to maintain the excellent performance of your vehicle. In addition, this motor oil brand also claims that their motor oil has a multi-viscosity. 

However, it is proven that it is not. So if you do not want your engine to be damaged in the long run, avoid this motor oil brand and look for those alternatives that are genuine in their quality.

3. Bullseye Motor Oil

Another bad motor oil brand is the Bullseye motor oil. It is considered to be the wrong choice for everyone. The reports are also from their users. 

A lot of users are disappointed and complaining about the motor oil manufacturer. Some people also rate the motor oil as doing nothing to your engine. Another rating says that this motor oil does not reach any good motor oil specifications and requirements. 

This brand beautifies their bottles and their physical products, and they put the wrong label and put the wrong information in it. If you buy one of these brands and look at the label on their bottle, you will find out that their label does not match what is within the bottle. Their motor oil has a very low viscosity level. 

You will also notice that their motor oil provides no resistance to any friction. This motor oil is too antique, and they also have a very low level of additives. So if you genuinely care for your vehicle, do not feed it with this motor oil brand.

4. Petrol Motor Oil

Another motor oil brand that is full of deceit is the Petrola motor oil. This motor oil brand is impressive in its deception. They are providing falsified information to the consumers, and they are giving them false hopes and beliefs. 

This motor oil brand is also terrible in terms of its packaging. This motor oil brand will consume so much of your engine fuel. 

As a result, you will increase your fuel expense, and it will also cause severe environmental issues like pollution and the release of carbon into the atmosphere. In addition, this motor oil brand does not meet the criteria and is insufficient because of its shallow viscosity level.

It offers very poor lubrication, and they have very high volatility. Their viscosity on their motor oil cannot be defined, and if you use this, you will be experiencing some noises from your engine.

6. Xpress Lube Pro

It would help if you also avoided Xpress Lube Pro. This is a brand that is avoided by knowing drivers. In addition, this manufacturer does not grade their motor oil based on their viscosity. 

They should know the grading of SAE, but it seems this manufacturer does not. They are fighting on their way of SAE grading, and they are not right at all. When we talk about motor oil, the SAE grading is essential. 

Their motor oil has a lot of impurities, and their motor oil is functioning very poorly. You must avoid this motor oil brand if you do not want any issues and damages to your vehicle.

Bad Engine Oil Brands

Does the Brand of Engine Oil Matter?

Yes, the brand of the engine oil matters. This is because the brand will represent how good the quality of the engine oil is. Brands are the ones representing the product. 

Therefore, if the engine oil is good, then the brand will be good. In another situation, if all motor oil brands have the same kind of motor oil, then the engine oil brand is not essential. 

However, each motor oil brand makes their motor oil different. Therefore, you must look for good quality engine oil.


In summary, motor oil is crucial in maintaining the excellent condition of your vehicle. Therefore, you must choose a good quality motor oil so that your vehicle will also be in good condition. 

With that, a motor oil brand is essential. Therefore, it will be best if you avoid the motor oil brand mentioned above.
