freequently asked questions.
What is 0W?
0W stands for “0 Weight” and it is used to indicate the viscosity grade of motor oil. The “W” stands for “Winter,” indicating the oil’s performance in cold weather conditions. The number “0” indicates that the oil has a low viscosity and can flow easily even in extremely cold temperatures. Specifically, a 0W oil has a minimum kinematic viscosity of 3.8 cSt at 100 °C and remains pumpable even at -40 °C.
What Should Be Considered While Changing Engine Oil?
The vehicle should be in the ‘stop’ position and on a level surface. The engine oil should be drained while it is hot. Ensure that the old oil is completely drained from the engine oil pan. If the drain plug of the oil pan has been opened and the oil has been drained, make sure to reattach the plug and check for any oil leakage after adding new oil.
How Can We Tell If Engine Oil Is Contaminated?
To determine with certainty whether the engine oil is contaminated or not, it is necessary to analyze the oil both physically and chemically under laboratory conditions.
Does the Mineral or Synthetic Nature of Engine Oils Affect the Oil Change Interval?
Synthetic oils have many superior qualities compared to mineral oils. Longevity is one of them, and it can generally be said that synthetic oils provide longer oil change intervals compared to mineral oils. However, the oil change intervals are determined by vehicle manufacturers (OEMs) after a series of tests, and it is best to adhere to these intervals for the health of the equipment.
What Does the Darkening of the Engine Oil Color Indicate?
One of the functions of engine oil is to keep the operating systems clean. A high-quality engine oil, with its detergent-dispersant additives, helps disperse and absorb the carbon deposits formed in the engine, preventing them from adhering to metal surfaces. As a result, the engine oil becomes dirty and its color darkens. Therefore, if the engine oil appears dirty, it indicates that it is effectively performing its task.
What Are the Differences Between Synthetic Oil and Mineral Oil?
Synthetic oils are oils that are chemically synthesized. They are produced to provide lubrication in applications where conventional mineral oils may not offer sufficient performance. Synthetic oils offer superior protection at high temperatures, easier flow and pumpability at low temperatures, enhanced film strength under extreme pressure, and longer change intervals in demanding operating conditions compared to mineral oils.
What is the Purpose of Lubrication?
The purpose of lubrication is to reduce friction by separating two surfaces, to lubricate the surfaces and facilitate smooth movement, to provide cooling, to create a film between surfaces to minimize wear, and to prevent corrosion.
