What is engine oil specification?
The Society of Automotive Engineers (SAE) developed a scale for both engine (motor oil grades) and transmission oils. The second number after the “W” indicates the oil’s viscosity measured at 212 degrees Fahrenheit (100 degrees Celsius). This number represents the oil’s resistance to thinning at high temperatures.
What is engine oil viscosity?
Engine oil viscosity refers to how easily oil pours at a specified temperature. Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.

What are engine oil grades?
The low engine oil viscosity grades end with a “W” and are usually suited for winter use. For Eg: SAE 0W, 5W, 10W, 15W, 20W and 25W engine oils. The high engine oil viscosity grades are not marked “W” and are suited for summer use. For Eg: SAE 8, 12, 16, 20, 30, 40, 50 or 60 engine oils.
What are the 7 functions of engine oil?
The seven primary functions of motor oil
- Minimize friction and reduce wear. The most common and essential function of motor oil is to minimize friction and wear between components.
- Clean.
- Cool engine parts.
- Form a seal.
- Dampen shock.
- Prevent corrosion.
- Transfer energy.
Can I use 5w30 instead of 15W40?
5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !

SH – Introduced 1993 – has same engine tests as SG, but includes phosphorus limit 0.12%, together with control of foam, volatility and shear stability.
What’s the service rating of an engine oil?
Engine oils with a Service Classification prior to SN (including SA) are often priced close to that of API SN. The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API).
Do you need to know the grade of your engine oil?
Yes, different engines require different engine oils to function and operate normally. The car manufacturer recommends the engine oil based on the parameters of your car. You ought to know the grade of the engine oil your car needs as well. This will help you get the best performance from your motor.
Who are the overseers of engine oil specifications?
The overseers of oil specifications are still ILSAC, API and ACEA. But, as engineers look to improve power and economy, they are forced to issue proprietary oil specifications. These specifications are typically listed on the back of the bottle, on a product data sheet or the oil manufacturer’s website.
