Common Rail Diesel Doesn’t Need These Components – Every year there seems to be something new. Common rail, although it has been out for a long time, we can say is a new technology. A very drastic change in the diesel engine requires technology that involves electronics. This new diesel engine technology has an impact on other technologies and we will try to discuss one of them in this article.
Common Rail Diesel Doesn’t Need These Components
Oil is a vital component for all types of engines. This includes high-performance diesel engines with the latest common rail technology. The latest diesel engines are very different from the old diesel engines, which were on the average non-common rail.
If we pay closer attention, the old diesel engine oil had a high SAE, in other words, it was thicker. But getting here, the diesel engine oil is getting thinner. It was none other than the engine specifications that increased rapidly.
One of the main considerations when it comes to lubricants is the presence of a turbocharger. We will find the turbocharger in almost every modern diesel engine. Unlike the supercharge which uses its own lubricant supply, the turbocharge uses engine oil for lubrication.
The oil requirement for turbocharging is also different from the engine because the temperature and rotation are higher. But for diesel engines, turbocharge temperatures tend to be lower. An obstacle that is often experienced by older turbo diesel engines is the right oil for the engine, but it is problematic to lubricate the turbocharger.
Usually, a sign of damage to the turbocharger is the presence of white smoke coming out of the exhaust. And some also experience conditions of excessive oil consumption or wasteful of oil. To prevent damage to the turbocharger, at that time many manufacturers offered a tool called a turbo timer.
But now, modern diesel oil specifications have matched gasoline oil. Even in some ways more dilute. And some diesel lubricants already have a special formulation with the consideration of a turbocharged device.
One proof is that modern diesel engines no longer need a turbo timer even though the average turbocharger is used. And neither manufacturer recommends installing aftermarket turbo timers. As long as you follow the instructions for using the oil, a modern common rail diesel engine will be safe.
Oil Type For Common Rail Diesel Engine
Currently, the choice of diesel engine oil is more and more diverse. Even so, you should not carelessly choose diesel oil. If you choose the wrong one, it can be fatal to your vehicle. Because the oil packaging is usually listed (SAE) Society of Automotive Engineers.

SAE is a code for the level of viscosity (viscosity) of the oil. For that, you must know the right diesel oil for your favorite car. First, oil with SAE 5W-40 for diesel cars with common rail technology. Then 5W-30 oil can be used for diesel engines or gasoline engines.
After that, we can use 15W-40 oil for diesel-engined cars with an age of over 5 years or a mileage of over 70,000 km.
Why Do We Use Oils with Different Viscosities for Aged Cars?
It is interesting to read further that the manufacturer never recommends the use of different engine oils based on age. Any automotive manufacturer recommends oils of a certain viscosity only. And that applies to every age of the car. That is, whether it’s a 5-year-old car or 15 years old and over, the recommendations are still the same. Is this true?
I don’t blame what the auto manufacturers did. This is because manufacturers always recommend using original spare parts and standard manufacturer care on any car they issue. If you follow the manufacturer’s rules 100% then it is clear what the manufacturer says about the use of oil is true. And of course any age the car will still be safe and can work well.
But the facts on the ground are not so. In both developed and developing countries, the use and maintenance of vehicles are almost different from what they are supposed to be. That is, the treatment is not in accordance with the manufacturer’s recommendations. This also applies to car engine maintenance though.
Car engines are very susceptible to engine overheating problems or other engine problems. This results in users having to think critically to overcome them. If the engine is no longer at the factory standard, whether its maintenance is not optimal or because of other obstacles, we also need to reset the use of the oil. The wear and tear on the main engine components is the cause. If we use oil with low viscosity while wear and tear on the engine components have occurred, the result will be a very rough engine and the engine tends to overheat easily.
Therefore, I suggest that if you do not maintain your common rail diesel vehicle in a standard way then the oil you use should vary. For cars under 5 years old, you can use the manufacturer’s recommended oil. But if it’s been over 5 years, you should use oil with a higher viscosity than the standard. And so on for the age of the machine above 10 years and so on.
