gNewscar : If you are told to choose between Synthetic vs. Conventional Oils, which one do you think is best for car engines?. The deeper question is actually what is the difference between Synthetic vs. Conventional Oils Here you will get all the answers to many other questions that are on everyone’s mind.
People sometimes assume that the function of oil is only limited to friction protection. In fact, now oil has other functions such as guarding the stability of temperature, protecting from crust and rust, cleaning, closing gaps in the engine wall, and other things that can maintain the durability of your engine.
Synthetic or conventional oil: which type of oil is better?
People who pursue automotive will loudly answer synthetic oil, while entry level class drivers will choose the conventional one, because the price is cheaper and the quality is decent.
This opinion is not supported by scientific research.
Therefore, AAA conducted a study to compare synthetic oil and mineral oil from five different brands to find out whether there really was a difference between the two.
This research was conducted by analyzing several factors: temperature and other variables and how they affect the oil adhesion. Both types of oil are also tested for their boiling points, and how quickly oil evaporation occurs.
Then, how are the results?
When seen sticking resistance at various temperatures and pressures from the engine, on average synthetic oil appears more primed than mineral oil.
Synthetic oil is also more stable at high temperatures and leaves less deposits. One area that makes no difference is the rate of oil evaporation, where the two types of oil have almost the same evaporation speed.
From this result, it appears that synthetic oil in general can provide better protection for your car’s engine. If you are thinking of maintaining your car for a long time, then choosing synthetic oil is a good consideration.
Nevertheless, actually conventional mineral oil is still good enough to be used. Moreover mineral oil meets the standards for car eligibility. In addition, also consider the oil brands available on the market. It is very possible that there are differences in the quality of each brand, even if you say the same from the type of mineral oil
Difference between Synthetic vs. Conventional Oils
- Synthetic oil is more stable at various temperatures
- Fewer residues leave in the engine
- Stay fit when used in the morning or in cold weather
- Better adhesion and coating, so that friction between metals in the machine can be minimized
- More efficient because it is resistant to various changes in temperature
- Can protect the machine from scale
Keep in mind that conventional oil comes from refined oil, while synthetic oil is the result of chemical engineering. Because it is a chemical engineering, certainly the impact of synthetic oil is more leverage for cars.
Although it is actually good for all types of cars, the use of synthetic oil cannot be chosen haphazardly. Also note the suitability of the oil type with the engine type and year of production of your car. Full synthetic oil is most recommended for cars with modern technology such as those using a supercharger, turbo, or DOHC. Synthetic oil is also used for cars that want speed, because the gap between the narrower parts makes only synthetic oil capable of performing coating tasks.
For car manufacturers in 2001 and so on, you should always use synthetic oil, both semi and full synthetic ones. But keep in mind the price of full synthetic oil is more expensive than semi. If you drive at normal speed and only in the city, semi-synthetic is enough.
To check the quality of oil that you want to choose, you can see it through the API code. API, or the American Petroleum Institute, is an institution that provides oil quality standardization through various criteria.
In the oil code, there are two letters. The first letter is the type of fuel used, and the second letter is oil quality. The closer to Z, the better the quality of the oil. That is, the better it is in coating the engine and meeting the protection needs for car engines.
For cars fueled by gasoline, the code is S. The second letter, for example M. Means, suppose the oil code is SM. API SM oil is usually used for cars with the latest technology, which is designed to provide more minimal deposits in varying temperatures. For oil codes with the SL API, it is usually used for older types of cars, production is 2004 and below. There is also another code, namely SJ. The SJ API is used for manufacturers 2001 and below.
Sometimes the oil code appears like this: SAE 5W30 SN. What does that mean?
Let’s look at the 5W30 code again. The letter W is a symbol for winter. It says 5W30. That is, this oil has a SAE level of 5 at cold temperatures, and 30 at hot temperatures.
From this it can be seen that oil is able to protect your car’s engine optimally, even if the car is started in cold conditions. For that, in addition to caring for car components, paying attention to the quality of oil used can also be a determining factor for the durability of your car.
You can conclude too, that oil is a crucial factor when you talk about car type maintenance. Engines with certain years and specifications require different oil usage. Also pay attention to the length of time the oil change. Long changing the engine oil will actually be fatal.
It is also recommended to buy oil or lubricant that is still packaged properly. Avoid buying oil at random, especially if the seal seems open. It is feared that you were actually given used oil or fake oil. If this happens, your car might actually experience engine down. Buy car oil at an authorized agent or at a trusted repair shop.
