Aug 17, 2020 ยท Understanding Engine Oil Viscosity. The large numbers on a bottle of oil like 5W30 or 10w40 refer to its viscosity. It's loosely defined as the 'flowability' of the oil. Put another way, thin oil has low viscosity, while thick oil has high viscosity. So for example, beer has low viscosity and golden syrup has high viscosity.. Chrysler. Chrysler has three proprietary oil specifications for gasoline engines. They call these standards Chrysler Material Standards or MS specifications. The first specification is MS-6395 that covers 5W-20, 5W-30, 5W-20 and 10W-30 oils. This standard follows the API SM GF-5 standards with a few extra tests for Chrysler engines. "/>
Engine oil specifications explained
For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will. Monograde oils such as SAE 30, 40 or 50 are no longer used in latest automotive engines, but may be required for use in some vintage and antique engines. Straight SAE 30 oil is often specified for small air-cooled engines in lawnmowers, garden tractors. What Do Oil Viscosity Numbers Mean? Viscosity is the resistance to flow of a fluid. Motor oil viscosity grades are based on a scale developed by the API (American Petroleum Institute) lubricant organization. The values are defined in a specification known as API 1509 and are based on the resistance the oil gives to flowing at two different temperatures โ cold and high.
Jul 08, 2018 ยท The lower the โWโ number, the better the oilโs cold temperature/cold start performance. The 50 in a 20W50 means that the oil must fall within certain viscosity limits at 100ยฐC type high temperatures. Once again the lower the number, the thinner the oil: like a 30 oil is thinner than a 50 oil at 100ยฐC etc. You may have also seen API .... Stable, stay-in-grade oil intended for use at extended drain intervals in petrol engines and car & light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a high temperature / high shear rate viscosity of 2.6 mPa*s for xW/20 and 2.9 to 3.5 mPa.s for all other viscosity grades. These oils are unsuitable for use in some engines. Consult owner.
This specification is built on the ACEA C3 standard but also contains elements from the ILSAC GF-4 deposit formation test and low-temperature sludge build-up test. Legacy MotorOil Specifications GM-LL-A-025 Special GM approval for long-life engineoil for gasoline engines. Viscosity is SAE 0W-30. Product meets ACEA A3/B3.. 1) The purpose for which it is intended (i.e. Motor oil, Gear oil etc) 2) The viscosity (i.e. 10w40, 5w30 etc for Motor oils and 80w90, 75w90, etc for Gear oils) 3) The specifications that it meets (should contain both API and ACEA ratings) 4) The OEM Approvals that it carries and the codes (i.e. MB229.3, VW503.00, BMW LL01 etc).

The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature. For example, a 5W-30 motor oil.

API (American Petroleum Institute) specifications are often seen on oil containers and they show the minimum standard of oil that can be used in an engine. You can't really use the API specifications to measure the quality of an oil as many of the top end ester based oils meet API SL rather than the latest API SM specification.
The API cautions that any oil with a classification of SE should not be used in engines built after 1979. Furthermore, the SG classification cannot be used in engines made before 1993. The recommended correct oil to use for all gasoline engines, in any year, is the classification SM. For engines made 2001 and before, classification SJ is. May 23, 2022 ยท JASO T903 & M345.

Here in 0W-20, the viscosity of the oil is 0 when... 0W-30 The 0W-30 oil is engineered to behave as a 0 weight oil at the starting temperature and a 30 weight oil when the... 0W-40 The 0W-40 oil is engineered to .... The difference in the viscosity is the reason you see multiple numbers on grades, such as 5W-30. The number preceding the W is a measurement of the oilโs flow at 0 degrees Fahrenheit. The lower the first number is, the better the oil flows at below freezing temperatures. So 0W-30 would be a better cold-weather lubricant than 5W-30..
API FA-4 and the FA-4 Donut identify certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 PLUS, CI-4, and CH-4 oils. Call: 1-855-405-6789 Hydraulic Oil Fluid Price List.

5W-30 and 5W-40 are 2 common types of engine oil that you might come across. The '5' refers to the viscosity in cold weather and the 'W' stands for 'winter'. The '30' or '40' refers to the oil flow at higher engine temperatures. '30' is often for newer petrol engines, while '40' is often for older or diesel engines. Almost all motor oil data sheets will list the kinematic viscosity values of an oil at 40ยฐ C (104ยฐ F) and 100ยฐ C (212ยฐ F). Unless you're an engineer or a serious oil geek, however, you needn't worry about these values. They're mainly important as factors used to determine other, more easily-understood specifications.

You can't really use the API specifications to measure the quality of an oil as many of the top end ester based oils meet API SL rather than the latest API SM specification. An old car engine might be perfectly happy with a few good glugs of old-fashioned SAE 20W 50 viscosity mineral oil, but engine technology has moved on and the demands on engine oils have moved on, too, with fully synthetic 5W 30 oil being the sort of thing you'd use in a modern engine..
What Do Oil Viscosity Numbers Mean? Viscosity is the resistance to flow of a fluid. Motor oil viscosity grades are based on a scale developed by the API (American Petroleum Institute) lubricant organization. The values are defined in a specification known as API 1509 and are based on the resistance the oil gives to flowing at two different temperatures - cold and high temperature. Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines.They typically consist of base oils enhanced with various additives, particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers. [citation needed].The main function of motor oil is to reduce friction.
