For example, an ISO 680 lubricant will have similar viscosity to an AGMA Grade 8 or SAE 140 gear oil. See how to properly check, drain and replace your Kawasaki. If you are used to working with one set of standards and suddenly get another thrown at you, this chart can provide a point of reference. There are many different grades of motor oil available, each designed for certain operating conditions. Oil is the lifeblood of your engine, cooling and lubricating everything that moves. So what’s the point of the chart? Basically, it allows users to determine whether or not lubricants will have similar viscosities. Engine Oil Performance and Engine Service Classification (Other than 'Energy Conserving') J183201708. Listed below them are the viscosity grades for these standards. These are ISO Viscosity Grades, American Gear Manufacturers Association (AGMA) grades, SAE crankcase oil grades and SAE gear oil grades. Viscosity is the ability of a liquid to resist flow how thick it is. The numbers in the middle will most likely look a bit more familiar. Still, it is commonly cited in lubricant product information. Choosing the wrong product can prevent a vehicle from starting or even severely damage the engine. More importantly, you're probably wondering what kind of lubricant you should be using in your engine. The measurement is specified by ASTM D2161, but is largely considered to be obsolete. You may have seen oil grades such as 10W-30 on a bottle of oil and been curious about what they mean. These measurements refer to the results of a specific test producing measures of kinematic viscosity. The results of the tests conducted on samples of these motor oils meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and. For instance, a low-viscosity oil such as an SAE 0W or 5W reduces engine friction and allows engines to start quicker when the weather is cold. On the other side, you have Saybolt Viscosities. Usually, these are tested at ☄0 and ☁00 Celsius and are almost always shown on product data sheets. It’s the most common unit of measure for viscosity and is expressed in cenistokes (cSt). It’s a measure of a fluid’s internal resistance to flow and shear under the force of gravity. Let’s take a closer look:įirst, let’s talk about kinematic viscosity. ASTM D4683, CEC-L-36-A-90 (ASTM D4741) or ASTM D5481.Viscosity grade comparison charts like this one are relatively easy to find, but they can be a bit difficult to understand. Test Method for Kinematic Viscosity of Transparent and Opaque Liquids A Test Method for Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature CCS or Cold Cranking Simulator, A Test Method for Apparent Viscosity of Engine Oils and Base Stocks Between –10 ☌ and –35 ☌ (For 15W, 20W, and SAE 40 HTHS limit is 3.7 instead of 2.9) References: (For 0W, 5W, and 10W, HTHS limit is 2.9 cSt.) 8 products Synthetic motor oils are inherently more stable and less prone to thermal breakdown vs. SAE J300 Viscosity table, SAE J300 Viscosity chart shown above is January 2015 revision. High viscosity thicker oils have strong film strength to protect metal to metal contact during high temperature and heavy load. Thin oils are easy to pump and help start engines quickly during cold weather. Lower viscosity or thin oils flow more easily at low temperatures than thicker oils that have a higher viscosity. See SAE J300 viscosity table below.Įngine oil viscosity refers to how easily oil flows or pours at a specified temperature. The Society of Automotive Engineers (SAE) developed a scale for viscosity for both engine oil (SAE J300) and transmission oils (SAE J306). Use only manufacturer recommended oil viscosity grades for your vehicles. Engine oil can be confusing our experts explain how to find out what oil your car needs, the different types of engine lubricant, and why oil viscosity. January 2015 revision SAE J300 viscosity chart now includes two new viscosity standards SAE 12 and SAE 8. Engine lubricants must meet viscosity requirements that are established by a number of organizations along with major equipment manufacturers. See all viscosities What Type Of Motor Oil To Choose Oil Types There are so many motor oils out there, which oil type is right for your vehicle Well, there are three basic types: mineral, semi synthetic blend and full synthetic. Viscosity plays a predominant role in the selection of lubricants for engines.
