What are the Best Synthetic Oil Brands

Are you having trouble choosing the best diesel oil for your vehicle? It seems like all of the brands, their products and their statements are more and more confusing and making the right decision simply seems very difficult.

Since the beginning of the automotive era, diesel engines have been there, and over the long course of its evolution, diesel engines were able to become the main choice for buses, heavy vehicles, pickup trucks, agricultural vehicles etc.

However, in the past two decades or so diesel vehicles have grown a lot and today these engines are competing with electric car engines and hybrid engines in passenger vehicles. One of the biggest improvements diesel engines have brought to the auto industry is the need for higher quality motor oils.

This is why more and more people are turning to synthetic oils, and a lot of people are calling them “the best engine oil for diesel cars you can buy”.

Do you know that over 80% of engine oil is made out of Base Stock and that the rest of it are mostly additives? In order to get a good synthetic oil, you will first need to have a good synthetic base stock. PolyAlphaOlefins in particularly, including Alkylated Naphthalenes and Esters as well.

These are the first and original base stocks for synthetic oil and they were made from building blocks with various chemical processes which ultimately lead to creating good oil molecules. There are a lot of performance advantages of using synthetic base stocks, especially PAOs. This means that any oil made from this material will offer those benefits as well.

What are synthetic oils?

What are synthetic oils

Most people know that the best synthetic diesel oil products give better performance than regular motor oils, however these oils also offer a lot of protection to your engine. So what are the differences between these two types of oils? Both of these oils begin under the surface, and all similarities end there.

Not only is synthetic oil refined, but during its production it also gets purified, distilled and reduced to the most basic molecules. This process removes all of the impurities from crude oil, while at the same time enabling all molecules individually to be customized for the demands of modern diesel engines.

All of these custom tailored molecules give a much higher level of performance and protection than any other conventional diesel oils. However, it’s not only about the the synthetic base, this is just half of the story. These oils also need the right additives in order to be effective.

Additives in synthetic oils

Now, let’s talk about those 20% percent that are included in thee oils. As I mentioned before, these are additives and they are highly complex and very important for the whole chemical structure of synthetic oils. They are added to improve the overall performance of the synthetic base.

There are engine oils that have an additive package which is bought separately and mixed with your base on your own. This is not a bad thing and it works. However, there are still different theories and research done on finding the best, well-balanced, and optimized additive formula that will allow these oils to be at their maximum potential, while at the same time protecting the engine.

The best best synthetic oil for diesel engines is a very complex mixture of synthetic base and in some cases, up to twenty different additives. It’s similar to buying frozen food and taking it home to put it in your microwave to heat it up so that it tastes good; it’s very inexpensive and it can save you a lot of time.

However, if you want to make it truly tasty and exceptional, you’ll need to find additional ingredients that improve its taste. This might take some time and additional costs, but once you get the right mixture, your diesel engine will work flawlessly.

Reasons why you should use synthetic diesel oil

Reasons why you should use synthetic diesel oil

So, let’s get to the actual benefits of using best synthetic diesel oil for your machine. As I mentioned before, it’s all about better protection of the engine and better performance. Here is how chemistry offers real benefits.

Improve engine wear protection

An engine is a big set of mechanical parts which all come in contact with each other while the engine is operational. Additionally, these parts can move at very high speeds, creating an extreme environment where it’s not uncommon for parts to break or wear down in the intense environment.

This is where motor oil comes into play, as one of their main purposes is to create a protective layer between all of those parts and ensure that they take less damage when the engine is running. All conventional oils are broken down very easily and they quickly stop being protective.

Given the fact that synthetic oils have special additives and that their molecules are already broken down and customized for these purposes, these oils will last a much longer time and protect the engine from wear.

They are better for low temperatures

When you leave your car at night in the cold, all of the oil settles down. However, when you get up in the morning and start up the engine, the oil starts flowing through the vital parts of the engine to protect it from friction and wear.

All of the traditional oils need much more time to start running smoothly throughout the whole engine. When it’s cold outside, this will be even more difficult, as conventional oils need higher temperatures to start flowing.

However, synthetic diesel oils are engineered in such way that they have the ability to flow at much lower temperatures and they can protect your engine as soon as you start your car.

They are better for high temperatures

When your engine runs for a long time, or you drive your vehicle at higher speeds the engine can get really hot. If your engine remains heated up over a longer period of time it can break down conventional motor oils and even cause them to evaporate.

This can lead to severe consequences, including extreme wear and damage to your engine parts. All synthetic diesel oils are engineered to be able to endure extreme temperatures and not get damaged or broken down. If you live in a hot climate, this is extremely useful.

One specific feature of synthetic oils is that they have great thermal stability, meaning that the temperature changes, no matter if hot or cold, will not affect the oil and that it will stay pretty much the same as in “regular” conditions.

They keep engines cleaner

When your engine is working and as oil circulates through it and around, it can pick up some substances that might harm your engine. Regular oils can form into sludge from these deposits and top circulating fluently through your engine, which can ultimately lead to lower performance and even reducing the engine life.

Synthetic motor oils are engineered to have less impurities than regular motor oils and they have the ability to resist forming into sludges. This is how less deposits will be formed in your engine while at the same time, it will work smoothly.

The best synthetic oils for diesel engines

Motor oil is like the blood of your vehicle’s engine, it circulates around to give the engine everything it needs to run smoothly without any damages. A lot of auto manufacturers, no matter if we are talking about cars, bikes or trucks, prefer that their customers use synthetic motor oils instead of conventional ones.

Not only will your engine have better performance and be protected, but the best diesel oil products also need to be changed less frequently. On top of these things, synthetic oil also reduces the noise the engine makes.

One of the most important things you must decide as a car owner is what motor oil you will use for your engine. Sadly, a lot of people make bad decisions due to their lack of knowledge or accept bad suggestions from their technicians who simply have a deal with some motor oil company.

Here is a list of best diesel oil products you can find; they might be more expensive, but bear in mind just how much longer they will last and how much better they will be for your engine.

Amsoil synthetic motor oils

Amsoil is supposedly one of the first companies that made a completely synthetic engine oil. No matter if this is true or not, the fact is that they have one of the best base stocks and additives you can find.

This is a company that carries a great reputation, especially because it has remained a family business until this day. A lot of important organizations including American Petroleum Institute have praised this company for the performance their oil gives. Their best synthetic diesel oil products are top class.

Amsoil synthetic motor oils

Mobil 1 Motor oils

Mobil 1 is an oil company that has been researching, manufacturing, and developing new synthetic motor oil solutions since the 60s. This company makes all possible types of base stocks, including group 1,2,3,4 and 5 as well.

Their oils are truly their own, as they develop them all by themselves. The fact that most aeroplanes and airline companies lubricate their aircraft engines with Mobil 1 oils shows just how high the quality of their synthetic products is. There are a lot of those who say they have the best diesel oil.

Amsoil synthetic motor oils

Castrol motor oils

Castrol motor oils are what you might call a well-rounded company that produces all kinds of oils. Their synthetic oils excel in high mileage, meaning that the oil will not fall off from the engine or break down during long travels. In this area, this is one of the best diesel motor oils.

Their synthetic oil also has the ability to stay on the engine parts for quite a long time, even if the engine hasn’t been started. On top of that, a lot of automakers suggest Castrol as their first motor oil choice.

However, one of the most amazing things about Castrol is that they have an oil selector tool which allows users to put in their vehicle model and engine, and the tool will tell you what oil is best for your vehicle. This is not always an easy thing to do, so points for Castrol for trying to help out their customers.

Pennzoil Motor Oils

Pennzoil is one of the big players in the oil industry and their products excel at making sure that there is no sludge buildup in the engine, and making it clean. They also offer a fuel saving calculator which is supposed to show how their oil reduces gas consumption.

This is a big company that is an official oil supplier for Ferrari. They do offer solid synthetic oils, but in reality they are not that special and this company is more about marketing than anything else. Still, this doesn’t mean their oils won’t do their job well.
