1. Liberty Motor Oil

The main purpose of using motor oil is to run your car smoothly and protect your engine using the lubrication that it serves. But if you use the motor oil of this brand, you are going to damage your engine for sure.

Also, the specialties that this brand is promising, don’t serve a maximum of those. As a result, there will be no blame upon you if you feel betrayed. You will literally get the viscosity level below 70%, which is totally unacceptable compared to what they are promising for each of their oil models.

Moreover, almost all of their motor contains volatility more than the allowed level. As with the increased volatility, the rate of evaporation increases; you understand how wasteful it is to buy, right? The additive of the engine’s motor oil increases the lubrication. But liberty motor oil brand has been found to have a lower level of additives than it’s required in every quarter.

2. Petrola Motor Oi

Firstly, the packaging issue is very concerning for this motor oil. You will be irritated by the packaging quality that it comes in. The low-quality packaging will disappoint you in the first place. Also, this brand misleads the user with the wrong information on the label. The viscosity level that they promise to serve is not real.

Whereas, they provide way below the level of viscosity to the user, which can be alarming for your car. Unknowingly even if you use it, it will create a massive danger to your vehicle. You won’t get the accurate SAE specification though they promise to provide that.

We noticed that with the very little amount of specification that they have, this oil brand is not suitable for most motor vehicles after the 1930s. So, if you own a new model of car, it will be dangerous for you to use the oil of this brand. So we have considered this as one of the bad motor oil brands that you should avoid.

3. Xpress Lube Pro

Here is another brand that has totally disappointed us in many ways. This motor oil does not provide even the minimum SAE grade that is required for the sae declared motor oils. Though almost all of their models promise to have SAE grades, the feedback is not what they show to us. This is totally misleading, and tests of their oil has proven it.

We assume that many of the riders and drivers do not use the old models now. Even if you use an old vehicle will you drive? To save you from big trouble, here is the truth. You can’t even use this oil for most of the modern models. Besides, after the element analysis, we have found many harmful substances that you should be away from.

4. Questron

Though they assure that they ensure premium quality in their motor oils, this is not true. In fact, we have found a lot of misleading in their labeling, ingredients, and even different properties that they serve.

First of all, we have tested this oil; one of their motor oil was known to be a premium grade oil, which is so wrong! We found literally no premium quality material in their labeled oil. Also, there was the presence of enough harmful substances, which can surely damage your engine.

Besides, you won’t be able to use it for many of the new models. Though you will never understand it before you buy and damage your engine. Also, this brand also does not meet the assured Viscosity Grade that they promise to have. So you can easily trust them and fall for their trap. Their cold Crank Viscosity at -25°C is of the least amount, which usually should be around 7,000 Max.

Almost all the motor oils of this brand are accused of misleading and false specifications as well. You may notice different labeling on the body of this product, but in reality, these are so fake! So imagine how much damage you are going to bring to your engine if you use this engine oil?

The specifications that this brand promises to have in oils are not the necessary specifications for multi-viscosity motor oil. So if you are not aware of what a multi-viscosity oil should contain, you will easily be fooled by their sweet talk.
