All you need to know about green engine oils

People often get confused about the term “green engine oil.” Are you one of them?

Well, it represents a class of engine oils, not the color of engine oils.

For a good understanding, let’s understand the meaning and the benefits of green engine oil and narrow down the best ones for your vehicle.

Here’s what we’ll cover:

What Is the Meaning of Green Engine Oil? 

You might be wondering about green oil. Well, It is not the color but the composition which makes the oil green. Green engine oils are composed of renewable resources which are petroleum-free. 

This biodegradable oil is environmentally friendly and suitable for all engine types.

Green engine oils prolong your engine’s life while protecting against wear and tear. They also improve fuel economy and reduce emissions. Their excellent performance includes high-temperature stability and low volatility. 

Let’s review some of their benefits in detail. 

What Are the Benefits of Using Green Engine Oil?

Benefits of green engine oils

Green engine oil offers several benefits for your vehicle. 

Environment Friendly

Green engine oil offers environmentally friendly solutions for your vehicle. It is made from renewable resources and is free of harmful chemicals. 

It is biodegradable, thus, reducing pollution due to a lower carbon footprint.

Superior Performance

Green engine oil increases your engine’s performance. From enhanced fuel economy to reduced greenhouse gas emissions, it guarantees all. 

It also offers a longer lifespan than traditional engine oils, which benefits eco-friendly vehicle owners.

Suitable for All Engine Types 

Green Engine oil is suitable for all engine types, making it compatible with gasoline and diesel engines. 

Thus, you can be more eco-friendly and cost-effective with your vehicle.

Increased Fuel Mileage 

You can use green engine oil to improve the gas mileage of your engine by reducing friction and wear on engine parts.

It means your car will consume less oil. Additionally, green engine oil improves your engine’s performance and longevity.

How Green Engine Oils Are Made?

Let’s find out:


The first step in the production of green engine oils is the refining of crude oil, which is a complex mixture of hydrocarbons and other chemicals. 

The crude oil is separated into different fractions or components for refining by heating it to 1000° C. These fractions undergo further processing to produce finished products such as gasoline, jet fuel, and diesel fuel. 

It ensures a deep cleansing process to remove impurities.


The next step is the extraction of animal fats and renewable resources from crude oil. It happens in two phases:

  1. Using a solvent for extracting animal fat from oil.
  2. A distillation process to separate the solvent from animal fat.

These animal fats and renewable resources then help produce green engine oils. 


Additives like phenols and organic amines in green engine oil improve the engine’s performance.

These additives enhance lubrication and minimize the possibility of oil breakdown. 

Can Your Engine Oil Look Green Due to Any Problems? 

Your engine oil can change colors. Green or dark green engine oil means no harm. So, don’t worry!

However, if your engine oil shows the following colors, it signals some issues.


If you notice that your engine oil has turned brown or muddy, it’s because of coolant mixing with the oil. There are other reasons too, but leaks in the engine cooling system are common.


Over time your engine oil will turn black due to getting dirty and full of soot deposits.

If you notice that your engine oil is black, change the engine oil. Soot deposits can cause all multiple problems, from decreased fuel efficiency to increased wear on engine components.

White Milky 

If your engine oil turns white milky, it’s primarily due to water mixing with engine oil. While it may seem alarming, it isn’t always a cause for concern. 

It frequently happens mainly due to the condensation of water droplets.
