Functioning of engine oil will improve and are cost effective, therefore, no need to change engine oil frequently. The desirable properties of engine oils cannot be achieved economically by physical and chemical processing of crude oils alone. Therefore, engine oils are produced by blending mineral base oils and chemical additives for achieving the desired properties. Viscosity Index improvers are used  in multigrade engine oils for improving  viscometric  and rheological  properties. Different Viscosity Index improvers modify the rate of change of viscosity with temperature, they cause  a minimal increase in engine oil  viscosity at low temperatures but cause considerable  increase at high temperatures.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659147357\"\u003e\u003ch3\u003eRheology of Engine oils and Role of polymers as VI Improvers\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659147357","offer_id":39489773699165,"sku":"9783659147357","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c023f28f-80b2-4901-987a-e560b1ce904c.jpg?v=1774678071","url":"https:\/\/shop.autorenwelt.de\/en\/products\/rheology-of-engine-oils-von-sabiha-tanveer","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
