Synthetic motor oil’s pure and uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance.
Conventional lubricants, on the other hand, are refined from crude oil and contains elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium.
Again, an important sign of lubricant quality is its ability to flow at low temperatures. When temperature drops, motor oils thicken and move slower, causing parts of your engine to remain unprotected for a short period of time.
The short clips below compares the way two different 5W-30 motor oils perform under very cold temperatures.
One is a Synthetic 5W-30 Motor Oil and the other is a leading Conventional 5W-30 Motor Oil.
This test shows the superiority of synthetic motor oil in cold weather. The synthetic oil readily pours while the conventional motor oil seems like it really is frozen,even after over 4 minutes.
The synthetic oil is more fluid at cold temperatures than the tested conventional oil, giving you 36% easier and faster cold starts.
This means that synthetic oil can reach vital components faster, providing more immediate engine protection and reduced wear.
