what is sae viscosity grade Convert your oils between standards Several organizations ISO SAE AGMA have created competing standards to define oil viscosity ranges but most of them mean the same thing Oils grades that are on the same horizontal line with
In the SAE J300 standard 2021 the viscosity grades are 0W 5W 10W 15W 20W 25W 8 12 16 20 30 40 50 and 60 In the United States these numbers are often referred to as the weight of a motor oil and single grade motor oils are often called straight weight oils The grades with a W designation are considered Winter grades and denote an engine oil s low temperature properties while non winter grades denote an engine oil s properties at the operati The purpose of the ISO system of classifying viscosity grades is to establish a viscosity measurement method so that lubricant suppliers equipment designers and users will

The key lesson SAE viscosity rating indicates the oil s thickness but it does not grade the actual quality or performance For that you need the API quality rating like SN Plus There are a few classifications of viscosity but the two main classifications you will come across are ISO and SAE ISO international standards organisation is the European derived system and SAE society of
The Society of Automotive Engineers SAE set parameters for multigrade oils and viscosities base upon cold cranking viscosity pumpability and cST measured at operating temperature The Society of Automotive Engineers SAE viscosity grading system for engine oils consists of W grades that define low temperature viscosities and straight grades that put further limits on high temperature viscosities

The new viscosity grades are SAE 8 and SAE 12 defining new limits for future engine oils built for even better fuel economy Both SAE 8 and SAE 12 are operating temperature viscosity grades so they have minimum and maximum Use our oil viscosity comparison chart to identify and reference thickness at different temperatures for engines and machinery for ISO VG AGMA SAE Auto and SAE Gear lubricants
What are the different viscosity grades of engine oil How do you know what the right viscosity grade is for your vehicle The Society of Automotive Engineers SAE has developed a SAE ratings indicate oil viscosity which is vital for lubricating engine parts effectively Additives like zinc and phosphorus provide anti wear protection and maintain oil
