There are generally three types of engine oil, you can pick one of them to fill in your car, motorcycle, bus, truck, etc. The three types of engine oil are mineral, synthetic mixed, and fully synthetic oil. Which one is the best engine oil for you is determined by the four keywords below.
So, since mineral oil is the least refined of the three, it is less expensive but offers less protection, efficiency, and performance than the other two.
Semi-synthetic engine oil combines synthetic and mineral oils to offer improved performance at a lesser price than full synthetic engine oil. Because it is so highly refined, fully synthetic engine oil is the most expensive yet provides the highest protection and economy for any car.
Additionally, it is divided into categories for various engine types, such as gasoline and diesel engines. For instance, you can find synthetic oil for diesel engines or mineral oil for gasoline engines elsewhere.
The recommended engine oil
When it’s time to replace the oil in your car, the first thing you should do is pick the best kind of oil—and don’t forget about your own wallet.
The types of ideal engine oils are considered in light of how well they work with the engine. Here are the 4 keywords to determine that you have chosen the right engine oil for your car
- The type of oil is either mineral, semi-synthetic or fully synthetic
- viscosity code
- comply with API standards
- well-known brands
For product trust, well-known brands are chosen. Among the brands of engine, oil producers are Petronas, Shell, Castrol, Valvoline, and many others.
Engine oil for an old car
If your car is older, you might choose to use mineral oil. If your car is brand-new and has a modern engine, full-synthetic oil is the best option.
It is important to remember that the “recommended” oil from the owner’s manual is truly ideal; no oil producer knows the requirements of your car’s engine better than the car’s manufacturer.
Each engine oil is bottled with a code like 15w 40 and the API symbols API SN, API SP, and API SG underneath it.
The oil viscosity
The viscosity code is the same whether the oil is thick or liquid. The resistance to the flow of oil is a measure of its viscosity. Oil viscosity is determined by two numbers.
Winter is represented by the letter “W” at the end of the first numeral. When the engine is operating, the oil is cold, and this measurement describes how the oil flows under those conditions. The second number is determined by how oil flows when heated above the temperature at which an engine normally operates.
which one flows better
The flow will be better the fewer the number. Therefore, at startup temperature, engine oil 5W-30 will flow more easily than 10W-30, while at operational temperature, 10W-30 will flow more easily than 10W-40.
This is crucial because engine oil naturally thickens at low temperatures and thins at high ones. When it’s chilly outside, engine parts are better protected by thin, low-viscosity oil that flows more smoothly. The best oil for preserving film strength to safeguard the engine at high temperatures is often thick, high-viscosity oil.
American Petroleum Institute (API)
The American Petroleum Institute (API) is the national trade group for the oil and natural gas sector in the United States. It brings together the various players involved in petroleum production, refining, distribution, and a variety of other processes.
Gasoline and Diesel engine oil
They also develop industry standards for motor oil energy savings among other technical standards, including measuring techniques, pressure vessel design requirements, etc. Diesel and gasoline are the two groups. The spark ignition is under category S for gasoline, and compression ignition falls under category C for diesel.
The letter S or C is always followed by a different letter. For illustration, SM or CF. The more recent the oil technology, the higher the letter. Higher requirements will take the place of lesser letter grades for newer oils. For instance, backward compatibility means that oil that meets SN criteria can also be used in vehicles that require API SM, SL, and SJ.
However, you must be mindful of the engine’s construction year. Modern chemistry could not be appropriate for or compatible with outdated engine design and construction materials if the engine is too old. Let’s examine how it functions by category.
All API classifications for gasoline are listed below. It is primarily for passenger vehicles because most automobiles in Malaysia run on gasoline instead of diesel.
