Synthetic oil is a type of lubricant that’s made from petroleum or a similar material. It’s used in diesel engines to prevent the engine from seizing, and it can also reduce fuel consumption.
If you’re wondering if synthetic oil is better for your diesel engine, then this post is for you. Today we will briefly discuss this topic and provide you with the most acceptable answer. Besides, you will learn
- Is it better or not
- Combat between synthetic oil and regular well

Is synthetic oil better for diesel engines?
If you want to know the shortest and simplest answer, then it is yes. Synthetic oil is covered with plenty of features and advantage that makes it more suitable than other regular oil.
From better flow rating to environment friendly, you will find synthetic oil one step ahead of convenient oil. Let’s have a look at some advantage of synthetic oil that makes it ahead of regular oil:
Synthetic oil offers a better flow rate, especially in colder weather. Besides, it allows the engine’s critical moving parts to be enhanced lubricated on start-up.
It usually loses less viscosity at high temperatures. As a result, critical lubrication gets ensured under high engine loads.
Oil change interval
As the synthetic oil is less prone to coking and includes superior additive stability so it offers a longer service life. Even under most operating conditions, you will have a longer oil changing interval.
If you use HEUI injectors on your engine, you will get more advantages in applying synthetic oil. As this oil is subjected to more stress, synthetic oil is used as a pressure medium to control the injectors.
On the other hand, the oil is more resistant to thermal breakdown, oxidization, and slugging. Besides, it offers additional protection against motor wear and tear.
As we talked about earlier, it needs to be changed. The best idea is to follow the vehicle manufacturer’s suggested mileage for changing the oil. Remember that, you should change the oil filter while you change the oil. While most of the regular oil need to change 5,000 to 7,500 miles, synthetic oil can last from 6000 to 16,000 miles.
Exhaust gas temperatures
Another great advantage is, Synthetic oil can lesser exhaust gas temperatures by a considerable amount. It means the engine will operate at the highest efficiency and make less heat. As a result, the change of damaging and wearing to vital motor parts will reduce.
Usually, around 500 degrees is the normal operating temperature for a diesel engine however it can raise to 1000 degrees under acceleration.
As this engine oil is constructed with new production techniques and offers the advantage of mass production, the price of the oil is slightly high. But providing long mileage between oil changes will be a money-saving option at the end of the day.
Why synthetic oil is better for diesel engine
As you know synthetic oil is better for diesel engines, following comparison will feel you clear why it is better than regular engine oil.
Oil change frequency
What can be better than that you are using the same oil with a longer interval and riding smoothly? It will not only save your time but money. Synthetic oil is specially designed to last longer than conventional oil. Thus you will need fewer oil changes compared to the same time conventional oil.
Synthetic oil comes with higher viscosity which makes it environment friendly. So you can use it suitably at any temperature. Conversely, conventional oil won’t let you enjoy this feature at all.
Firstly it may seem to you conventional oil is budget-friendly as it is inexpensive than synthetic oil. But if you deeply analyze you will find synthetic more helpful sand money saving option. While you will need double conventional oil to run your diesel engine, using half of the amount of synthetic oil you can enjoy the same mileage.
Synthetic oil is designed with recent engine technology, it is highly recommended for a recent model car.
Which is the best oil for diesel engines?
However, most synthetic oil will be a better option for diesel engines, following some oil will work best. These are packed with plenty of quality features to offer smooth and safe riding
- Mag 1 Full Synthetic 5W-30 Motor Oil
- Castrol EDGE Extended Performance 5W-30
- Valvoline SynPower 5W-20 Full Synthetic Motor Oil
- Mobil Super 5W-30 Synthetic Motor Oil
- Royal Purple Synthetic Motor Oil
Do I Need Special Oil To Run Diesel Engines?
Like regular gasoline engines, diesel engines also need regular maintenance like oil changing. It greatly helps run the vehicle’s parts smoothly. In this case, it needs especially design lubricating oil is designed for diesel engines.
How Often Should I Change Synthetic Oil In A Diesel?
The car’s user manual is the best idea to know about regular oil change intervals. However, most synthetic engines can last up to 16000 miles but every 7,500 miles you should change the oil in your diesel engine.
Can I Mix Regular Oil And Synthetic Oil?
Of course, there is no problem mixing synthetic and regular motor oil. However, it will reduce the superior performance of synthetic oil but some car owners do that to save some bulk.
About Diesel engine
Diesel engines are relatively high performance so they need high viscosity oil. Besides, this type of engine performs at a much higher compression ratio comparing gasoline engines. As a result, the oil you will use in this engine should have the ability to withstand tremendous forces up to 50,000 psi. That’s why 15W-40 viscosity oil is most recommended for diesel engines. These oils are thicker and higher.
We intended to know you are synthetic oil better for diesel engines or not. Hope you get the answer after reading the guide. At the same time, we have provided you with a piece of massive information on synthetic oil that will help you choose the oil confidently.
So let’s use the most suitable oil for your specific diesel engine and enjoy the most smooth and comfortable riding for long and keep maintaining a healthy diesel engine.
