[QUOTE="oldnfast, post: 1861920, member: 13423"] :beer: Hi guys. Can I play too? First off, no oil gets thicker as it gets hotter. The oil gets thinner. What increases the viscosity is the polymers expanding (uncoiling) as they get hotter. Polymers enable manufacturers to produce "multi-grade" oil. Whatever the first number in the designation (0, 10, 20, etc.) is the actual grade of the oil in that container. The second number is the viscosity equivalent of that oil at 100 degC. The higher the second number, the greater the amount of polymers added to the oil. Many individuals apply fossil characteristics to synthetic oil. They are completely different products. Synthetics contain no parafins, no ash, and their flash points are much, much higher. Due to the high flash points, loss of shear film at high temperatures (a huge concern with fossil oils), is a non-factor with synthetics. This is why the automobile manufacturers have no hesitation recommending 0 & 5 weight oils. [/QUOTE]
