What does 0 20W mean?
What Higher-Cost Engine Oil Gets You. Breaking down the 0W-20 code, “0” is the oil’s viscosity at startup when the engine is cold, “W” stands for its winter certification, and “20” is the viscosity at higher temperatures. Lower numbers designate thinner, lower-friction oil.
What is the viscosity rating of an engine oil with a classification of 0W-20?
Multi-grade viscosity motor oils are able to perform at a wide range of temperatures. For an SAE 0W-20 oil, the “0” is the cold-temperature viscosity rating (the “W” stands for “Winter”), and the “20” is the high temperature viscosity rating.
What is 0W-20 oil synthetic?
Mobil 1™ 0W-20 is an advanced full synthetic motor oil designed to help deliver outstanding engine protection and enhanced fuel economy benefits to keep your engine running like new and protect critical engine parts for up to 10,000 miles between oil changes*.
Is 0 20w oil only synthetic?
Most 0W-20 oils are synthetic (even if only group III synthetics). Many 5W-20 oils are semi-synthetic. When you start with a 0W base oil and depend on polymers to increase the viscosity as the engine heats up, you are betting a lot on all those polymers.
What does the number W mean in viscosity of oil?
The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. Is thicker oil better?
What’s the difference between cold and hot oil viscosity?
The viscosity of hot oil is measured using different test parameters than when the oil is cold, so the numbers after the “W” don’t relate to the numbers in front of the “W”. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
What does the 10W 30 mean in viscosity?
It stands for “Winter” and that is the key to understanding viscosity grades. A 10W-30 is a multi-grade (two viscosities) motor oil, and as the name implies, it meets more than one grade. Forty years ago, there were winter grades for cold weather and summer grades for warmer weather.
What does the viscosity index in SAE mean?
Description. Currently, most automotive engine oils are multigrade oils, while oils for restricted usage, e.g. for seasonally used engines like lawn mowers, are often monograde oils. While the two numbers specify the SAE viscosity grade, the viscosity index shows the temperature related change of viscosity.
What should the temperature be for 0W-20 synthetic oil?
For example, Mobil1 0W-20 oil pours at temperatures as low as 47 degrees Celsius and protects at oil temperatures as high as 205 degrees Celsius. This is far outside the normal operating range for almost all vehicles. Vehicles in past decades needed thicker conventional oil with viscosity ratings of 10W-30 or higher.
What should motor oil viscosity be at 210 degrees?
For example; if you have a SAE 10 motor oil it will flow like a 10W at the colder temperature. But at 210 degrees it will be a SAE 10 giving us a 10W-10 or SAE 10 viscosity rating. Obviously this is good at cold start up, but terrible at engine operating temperature especially in warmer climates.
What does a W mean on an oil viscosity rating?
When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature.
