Diesel Engine Oil

Diesel Engine Oil - About the maintenance of diesel engines, especially for diesel engine oil that is used. With the selection of suitable oil consumption, of course, will be more economical in its use. It would be good not to use the latest tech oil on old diesel engine type. Because diesel engine oil with this latest technology is not only the price is more expensive, also not necessarily compatible with your diesel engine and if the wrong selection of engine oil can cause problems on the machine itself. This kind of thing because the old type of engine is made with a classification in accordance with the characteristics of the old oil.

There are various brands of engine oil on the market, but when we want to buy engine oil that needs to be noticed is about the viscosity of the engine oil, because each type of engine has a viscosity of different lubricants, such as for gasoline engines and diesel-fueled engines for lubricating oil use also have differentiation. we often hear the term SAE in bottled oil this is an abbreviation of (Society of Automotive Engineer) is a standardization institute specializing in the automotive field. such as ISO, DIN, JIS.

Oil function on diesel engine

A good oil is a lubricant that dissolves easily and will change color after use because the nature of the oil is like a detergent as a cleanser. therefore for the seller of new diesel engine, if the machine is damaged when newly purchased because it is not given oil then to prove it when the oil is put to the engine when the engine is damaged then the oil will be intact as before but when the oil has undergone a process use then the oil will change color.

The diesel engine oil functions are as follows:
1. Reduces friction, because without oil the moving metal part is tangent to rub against each other, and the friction that caused the metal parts become worn and quickly heat.
2. Sealing, the oil will help seal the gas, so the narrow distance around the piston ring is filled with oil to ensure good sealing and perfect.
3. Cooling, the oil can cool the piston and bearings, the oil also removes heat from the parts then transport it to the oil container.
4. Cleaner, oil also works to remove dirt, carbon to keep the engine clean.
5. Prevention of rust, oil coat the surface of metal parts and prevent rust.

Diesel engine oil change intervals

Diesel engine oil function is very important therefore the maintenance process and its replacement must be noticed, for example for new diesel engine should do the change of oil after 50 hours of usage then the to throw   the remaining grams of dirt in the machine out, then do the change of oil machine after 100 working hours or at most 3 months. Sometimes for some people, this oil change process is often not in the attention because it is considered trivial but this is what causes the engine sometimes run out of oil and make the engine hot fast.

Diesel engines with irregular engine oil changes will be easy to experience problems, most quickly damaged parts of the piston, piston rings and cylinder liner that quickly wear out, many users who do not know or underestimate the engine lubrication system so it will be allowed for months even up some years the diesel engine oil is never replaced only added, so sometimes the machine that age is still young but has suffered serious engine damage, this may be one of the results of overly ignoring the problem of engine lubrication or rarely do the engine oil change.

The function of oil for the diesel engine is very important and vital then, therefore, do not forget to do the engine oil changes according to the time-periodic maintenance, so that diesel engine can have a longer service life.

Oil type

For the oil itself has several types of them:
• Mineral oil, oil made from refined and refined petroleum.
• Diesel engine oil fully synthetic, this type of oil is designed to produce more effective performance in comparison with mineral oil. Synthetic oil consists of Polyalphaolifins that is the cleanest part of the mineral oil separation of gas.

Classification of engine oil

SAE (Society of Automotive Engineer) classification of diesel engine oil is actually the same as the gasoline engine. SAE ie viscosity level, vehicles usually use SAE 10W-50, 20W-50 or 5W-30 oil. Quality/grade in the oil also needs to be noticed, which is shown by the API Service Classification, such as CD, CG, CF-4, CH and so on. The best quality that exists today is the API service CI.

Viscosity The best oil, what thick or thin?
The oil viscosity is determined by the lubricant supervisory agency (SAE), the smaller the oil SAE the more viscous the oil. For example, SAE 15w-40w oil is thicker than oil with SAE 30w-50w code.
The question is, is the dilute oil better for the machine? Each of the specifics of the oil specification must have its own effect. When using a more dilute oil, the engine effect is easier to rotate. as well as the resulting performance can also be more quickly realized.
But the bad effect, the sound of the engine sounded noisier. And because the resulting vibration is also noisier. When the machine in feel has higher performance, generally the driver likes to play with speed. Resulting, the age of the finished machine component is shorter.
Momentarily when using a more viscous oil, engine sound can be muffled well, until more smooth. bad, the machine so the weight spin until fuel consumption becomes more wasteful.
It is good to use the standard viscosity (SAE) that the manufacturer has decided on, where this sort of thing has gone through various test runs. And use the oil that is only made for diesel engines, because now many manufacturers who claimed the oil can be used for diesel engines and gasoline engines. Excepting the offer of oil manufacturers who have been famous, because they generally have done trials and research on the oil.

For machines that are old, usually, workshop recommends using a more viscous car oil. This is because the components of the old parts of the friction machine have been loose, not meeting 100% as in the new car engine. Why is that? Because the thicker diesel engine oil fills faster in the gap between friction components.

Diesel engine oil selection guide

Many brands and types of car oil circulating in the market with specifications are sometimes confusing. Expensive oil is not necessarily good for your vehicle. So this will save you in diesel engine oil change cost.
There are many guidelines that need to be understood so that the use of oil fits with the characteristics of the car engine that we have.

To be clear, here is a brief description of the Oil Election Guidance Tips on Diesel Engines:
1. The first thing to understand is the specification of your vehicle engine. In the manual has described the engine technology and the type of oil that fits. Any brand, in essence, the same if the specifications can be received by the car engine.
2. Observe the level of viscosity. The cars at this time, especially those that have no frills VVT, VVTi and the like. Minimum use oil with 10/40 or 5/30 viscosity. Such machines do not fit when paired with oil with the viscosity of 20/50 or more thick.
3. Pay close attention to other code such as API. Special SM APIs for new technology cars are designed to provide the best high-temperature precipitation control. For generations, in the beginning, the car output 2004 down, it is recommended to use the SL code. Then there's the SJ code for 2001 down.
4. The letter "W" is behind the initial number, which stands for "Winter". eg SAE 15W-50, it has a high viscosity SAE 15 for cold temperatures and SAE 50 in hot temperatures. With these conditions, the oil will provide maximum protection when the engine start at extreme conditions though.

On the packaging of engine oil, there is a number behind the letter SAE that's what shows the degree of viscosity. it shows diesel engine oil grades. for example if any SAE 20 code indicates the oil has a viscosity level of 20 according to SAE standard. If a multi-grade code number such as 10w-20, this code means that the lubricant has a viscosity that varies according to ambient temperature. for the letter W behind the number 10 stands for Winter. This means that the lubricant has the same level of viscosity as SAE 10 when the temperature is cold and SAE 20 when the air is hot.

5. Synthetic oil is generally recommended for the latest tech machines (turbo, supercharger, DOHC, and others), require better lubrication, where the gap between metals is narrower or more precise. Only synthetic oil that can coat and flow prime.
6. Can change the brand of oil, as long as the same viscosity code. It's good not to do up (increase the volume) because there are burn marks in the fuel area that need to be thrown on the old oil.

Diesel engine oil change

Checking the oil every week needs to be done, because of the liquid, we can know whether the vehicle is worthy of use or not.
Checking the oil condition also does not require a long time. You just pull out the oil checking stick (dipstick), which is usually obvious on the machine. What can be detected by engine oil?
If the oil color is not much different from the first time it is filled into the machine (usually tends to be translucent), it means the machine is in top condition. All you need to do is just turn on the engine and go to the destination.

However, if the diesel engine oil is black, it means it's time to change the oil. If you have a container, you can do it yourself. But if you do not want to bother, just take it to the nearest garage.
Oil is white or like milk means there is water mixed. Water and oil can mix, due to a hole in the separation wall inside the machine. Or it could also be a hole formed in the radiator when the vehicle uses one type of radiator to cool water and diesel engine oil cooler.

If there is a smell of gasoline, then there is the possibility of problems in the components inside the machine. Immediately check into the workshop, because the mechanics can know which components may be damaged.
When the oil is much reduced, then immediately check the floor under the car. as this indicates the diesel engine oil leak sealer. If there is no oil leak, then it could be burning oil along with gasoline. The sign of a thick white smoke from the exhaust.
This smoke due to damage to the piston ring or valve where the fuel mixture into the combustion chamber. If this is allowed, then over time the machine will be damaged.
hopefully, this simple article can provide benefits for all of us and I apologize if there is any wrong in the word and writing, see you again in the next article on other diesel engines other than diesel engine oil.
