Viscosity is the flowability of liquids. A liquid that is relatively viscous can be described as viscous. Water, for example, has a low viscosity compared to honey. In this example, honey has a higher viscosity at the same temperature.<\/p>\n
A high-quality lubricant maintains its viscosity under different temperature and operating conditions over a longer period of time.<\/p>\n
\u00a0<\/p>\n
Most of today's engine oils are multigrade oils, e.g. \"5W-40\", i.e. they retain their lubricating properties at both high and low temperatures. The first number, followed by a W for winter, indicates the viscosity at low temperatures. The second, higher number indicates the viscosity at high temperatures. A multigrade oil minimizes viscosity differences during temperature fluctuations and can therefore be used at different temperatures, e.g. in summer and winter.<\/p>\n

Viskosit\u00e4t ist die Flie\u00dff\u00e4higkeit von Fl\u00fcssigkeiten. Eine Fl\u00fcssigkeit, die relativ z\u00e4hfl\u00fcssig ist, kann als viskos bezeichnet werden. Wasser hat z.B. eine geringe Viskosit\u00e4t verglichen mit Honig. In diesem Beispiel hat Honig eine h\u00f6here Viskosit\u00e4t bei gleicher Temperatur. Ein qualitativ hochwertiger Schmierstoff h\u00e4lt seine Viskosit\u00e4t unter verschiedenen Temperatur- und Einsatzbedingungen \u00fcber einen l\u00e4ngeren Zeitraum hinweg konstant.\u2026<\/p>","protected":false},"author":137,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[108],"tags":[],"class_list":["post-292","post","type-post","status-publish","format-standard","hentry","category-oel-lexikon","category-108","description-off"],"_links":{"self":[{"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/posts\/292","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/users\/137"}],"replies":[{"embeddable":true,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/comments?post=292"}],"version-history":[{"count":1,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/posts\/292\/revisions"}],"predecessor-version":[{"id":21585,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/posts\/292\/revisions\/21585"}],"wp:attachment":[{"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/media?parent=292"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/categories?post=292"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mathy-austria.com\/en\/wp-json\/wp\/v2\/tags?post=292"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
