Bad Motor Oil Brands to Avoid

According to our team’s research, Liberty, Petrol, Quaker, and Xpress are the worst motor oil brands to avoid. Let’s see the reasons:

Quaker State Q

Quaker State Q is the worst motor oil brand for failing to provide some primary advantages of motor oil. Firstly, this brand has a high price tag but needs to improve product quality.

Like Liberty Oil, Quaker State Q also claims many advantages, but most body labels have proven fake. Adding more, Quaker lacks some of the additives needed for lubrication to keep your car running smoothly. High volatility is the main reason to avoid this brand. It spreads quickly and can seriously damage the engine in the long run.

Quaker also claims multi-viscosity, but this is again a false claim. So to keep your car engine at its best, it’s best to look at other options.

The main reasons to avoid this is

● Little expensive

● High volatility

Liberty Motor oil

The main reason to avoid this brand is the company needs to be more proper to its word. Liberty oil has many benefits and properties, but it needs to provide an average-quality product.

There needs to be more than the percentage of the additive to cover the basic requirements of motor oil. Volatility and viscosity level are other significant drawbacks of this brand.

So based on all the information mentioned above, you must be aware of what this brand offers.

The main reasons to avoid:

● Low viscosity and high volatility level

● average quality

Petrol Motor oil

Like other worst brands, this oil misleads its users with wrong guidance and information. So it comes down to categorizing bad motor oil brands to avoid. Furthermore, the viscosity level stated on the packaging could be more realistic.

They offer an unacceptable level that can be alarming for the engine. Besides this, the SAE specification they promise is also fake and makes you dissatisfied with the quality.

Quality motor oil contributes positively to the environment, but petrol motor oil does the opposite. Therefore, this oil brand leads to high fuel consumption, which induces environmental problems. It would help if you considered some factors before deciding, and it is best to avoid them.

The main reason to avoid

● Not suitable, especially for newer models

● Low viscosity level

Xpress Lube Pro

You know that motor oil brands’ essential labels are viscosity grading and SAE, but Xpress Lube Pro eschews them. So due to this major flaw and many other reasons, this brand is one of the worst motor oil brands. Grading is just inappropriate and not fair at all.

Still, many harmful impurities contribute nothing but poor oil quality. Moreover, more than the functionality is needed for modern models. We do not recommend this for older models to avoid some significant issues. Finally, Express Lube Pro also has fake labeling and needs to deliver what it promises.

The main reason to avoid

● Inappropriate SAE grading classification

● Excess impurities
