Why an Oil's Viscosity Drops - Machinery Lubrication

2 days · Another way your lubricant could be losing its viscosity is through the loss or shear down of the viscosity-index (VI) improver. For example, if you are using a multi-grade SAE gear or engine oil such as a 10W-30, this oil contains an additive known as a viscosity-index improver. During use, the VI improvers can sheer down and break apart ...

Article: Low viscosity engine oils explained

A low viscosity engine oil is less viscous – or flows more easily – at both cold and hot temperatures. These engine oils can be identified through their motor oil classification. For example, in a 0W-30 grade, the ‘0’ refers to the oil’s viscosity characteristics at low temperatures, and the ‘30’ its viscosity characteristics at ...

Viscosity And Engine Oil 101 | Brewer Hendley Blog

2019-3-26 · Engine oil viscosity describes your oil’s ability to pour at specific temperatures. As illustrated above, thin oils will have a lower viscosity and pour easier at low temperatures in comparison to thicker oils that will have high viscosities and require higher temperatures to increase flow. Engine oil viscosity …

What Happens if I Use the Wrong Weight (Viscosity) …

Just like using an oil with too high a viscosity may lead to problems in Josh’s engine, using an oil with too low a viscosity can have the same result. Oil that’s too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.

Low Viscocity Synthetic Base Stocks | ExxonMobil …

The CCS test measures the apparent viscosity of fluids at low temperatures (typically between -10 to -35°C), and high shear rates ( 10-6 sec-1). It measures the ease of engine cold crank starting. Lower viscosities at low temperature also allow the oil to flow and lubricate the engine parts, reducing strain and increasing protection.
