They say if the engine is considered a heart, then motor oil is surely the blood that flows through it. The following notion explained the unbreakable relation between both.
Motor oil lubricates the engine and prevents wear and tear along with maintaining its temperature.
If for some reason oil operation is disrupted, it could cause some serious damage to the engine or total seizure as well.
Based on the nature of their base oils, motor oils can broadly be classified into three categories i.e., conventional made of crude oil, synthetically made of imitation hydrocarbons, and mixed which are a mixture of both the previous types.
However whichever type the oil maybe there are a few criteria that any oil must fulfill to be declared a good motor oil.
These standards are set by automotive engineers who have defined parameters to ensure that the baseline performance is secured.
We will be seeing all these parameters along with discussing which brands don’t follow which ones.

How does the brand of Motor Oil affect the performance of the engine?
Other than different oil blends there are chemical formulas and manufacturing processes that are employed by motor oil companies to enhance the quality and performance of their products.
This makes each motor oil unique and highly separable from the other.
Therefore, it does matter a lot which brand of motor oil you are using in your vehicle.
Choosing the perfect Motor Oil
The additives are the backbone of any motor oil, both their quantity and quality matter in this regard.
Be careful! As few oils are available on market without any additives.
Such products are to be avoided at any cost because they were created for vehicles manufactured before the 1930s and could harm your modern vehicle.
It’s the rating given by American Petroleum Institute to all Motor Oils which are according to the compatibility with certain engine types, and they also define the period in between which the vehicles were manufactured. For example, SM is the highest API rating which is for gasoline engines made from 2004 to onwards.
International Lubricant Standardization and Approval committee gives specific ratings to the manufacturers who meet the special demands. Its highest rating is GF-6A.
Synthetic and semi-synthetic oils are more efficient than conventional ones as they not only have a higher capacity to hold additives but have provided extra chemical strength that increases the thermal resistance and decreases the oil’s volatility.
Viscosity rating denotes the viscosity at both cold and hot temperatures. We must decide which one to use according to our ambient temperature as each multi-grade viscosity has both upper and lower temperature ranges. Find the ones whose range best coincides with the temperate hot and cold extremes of our area.
The compounds in oil must be highly resistant to breaking down during high temperature and pressure situations.
The detergents and dispersants are responsible for cleaning sludge and other impurities that may appear in the oil over time.
Anti-corrosive agents are present in the oil to prevent the corrosion of metallic parts in the engine since water is also present as an impurity in oil which can trigger corrosion. Therefore, always make sure that oil comes with anti-corrosive agents.
It should not be producing any type of pollution and keeping the environment clean.
Engine Temperature Cooling
The oil with high thermal conductivity is recommended since it can efficiently cool your engine and prevent it from getting blown off. Oil with high hot viscosity will be able to properly disperse heat at high operating temperatures.
The rate at which an oil vaporizes due to the presence of short or simple molecules is called its volatility rate. Choose an oil with lesser volatility for a higher life and longer oil change intervals.

Recognizing Bad Motor Oil Brand
There is no hard and fast rule to detect whether this motor oil is bad or not but there are a few tricks that can help us to choose the right one. Few of these are
- Price is one of the biggest factors as you can’t expect very cheap oil to perform well.
- The second is irrelevant or missing information on the bottle which certainly arise suspension.
- No API or ILSAC certification is also a big NO as they surely aren’t up to the mark.
- Any department store brand which has nothing to do with the oil production business should also be avoided.
In this article we have covered the importance of engine oil, their types, and factors to consider them and of course the oil brands to avoid.
In the end, we have shared a list of brands that are considered trustworthy by the automotive community and have established their reputation as reliable and efficient manufacturers of Motor Oils.
We hope our article will help you to first; avoid all the bad motor oil brands and second; choose the one which best suits your vehicle.
