![]() ![]() For example, a higher viscosity index indicates that the kinematic viscosity of the lubricant will decrease very little when the temperature is increased. The VI is simply reported as a numerical value that has no units. I was expecting a non-linear like a post but another person said how can two data points give a curve (straight or not) which leads to my other question is how can two oils have similar end points and have diff VI unless they have non-linear relationships. I would expect depending on VI improvers they would not all react to temperature the same. I was just comparing and for a simple ratio I could not do the math. The MC is the odd one here with a much higher VI. Of course, in looking at other threads before I posted, there is the debate on whether high VI is really meaningful measurement. I used the VI calculator at Widman's and not all match from the published specs from the supplier's web site. I've been reading BITOG for some time but this is my first post. The subject of Viscosity Index like many things is very difficult to explain simply. There is really no substitute for much googling and internet reading. Problems getting or maintaining an erection is called erectile dysfunction (ED). It often affects males over the age of 40, but it can occur at any age.ĮD is a common, usually treatable condition in which a person is unable to get or maintain an erection long enough for sexual activity.
