ENGINE OIL VISCOSITY GRADES. The word viscosity describes how easily an engine oil flows. Here we explain what descriptions like 0W-20 and 5W-40 actually mean. There are three main types of motor oil: conventional, synthetic, and synthetic blend, the last of which combines some of the properties of the first two. Within these types, there are different grades or weights that are used for specific purposes. Car manufacturers usually specify 5W-20 or 5W-30 oil, though some require 10W-30. These three ratings cover just about every light-duty vehicle on the road, though this is changing as engines become more precise and fussy about specific types oil. If it performs like a SAE 0 motor oil at the colder temperature, then it will receive the SAE 0W viscosity grade. Consequently, if the motor oil performs like a SAE 20 motor oil at the reduced temperatures (the scale varies - see the chart), then it will be a SAE 20W motor oil. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. Most oils on the shelves today are "Multigrades", which simply means that the oil falls into 2 viscosity grades (i.e. 10w-40 etc) Multigrades were first developed some 50 years ago to avoid the old routine of using a thinner oil in winter and a thicker oil in summer. Car manufacturers usually specify 5W-20 or 5W-30 oil, though some require 10W-30. These three ratings cover just about every light-duty vehicle on the road, though this is changing as engines become more precise and fussy about specific types oil.

9 Jul 2018 This is where different grades of oil come in. Let's take a look at what oil viscosity is and how that translates into the numbers and letters you see

12 Sep 2019 Engine oil can seem complicated, with all the different brands an grades, but it's actually pretty straightforward. 17 Nov 2016 Wondering which engine oil your car needs? Read our guide to understand the different grades and viscosity. Find out what grades like 5W-30 15 Nov 2018 After a more careful search i found the following on a forum thread 5 Jul 2015 Oils must also comply with different quality standards. The standards required for your car will also be listed in your owner's manual. Sometimes

The carmakers usually specify a 5W-20 or 5W-30 oil, particularly for lower temperatures, with a 10W-30 oil as optional, particularly for higher ambient temperatures. These three ratings cover just

If your car is not an antique or air-cooled, the safest bet is to use a multi-grade oil. The first number on a multi-grade oil indicates the "cold" viscosity of the lubricant, and the second number the "hot" viscosity. For example, a SAE 10W-40 motor oil would have a viscosity rating

lubricating oils and products for other applications (grease, in addition to this, some vehicle manufacturers lay down approval standards aimed at optimizing

5 days ago Check your vehicle's handbook for the minimum oil quality specification and viscosity grade; but you may wish to choose a better one. Let us a take a look at the differences between these two types of oils and the as mentioned earlier, the viscosity for HD motor oils is in many cases different These types of oils that have a range of viscosity from thin to thick, low to high temperatures are known as multi-grade motor oil. They can also be called multi- 7 Sep 2012 In other words, if you tip a motor oil bottle over, how fast it spills out indicates its viscosity. The more viscous, the slower it moves. To indicate

What role does viscosity play in a motor oil?

The carmakers usually specify a 5W-20 or 5W-30 oil, particularly for lower temperatures, with a 10W-30 oil as optional, particularly for higher ambient temperatures. These three ratings cover just A car in Death Valley would need a higher number to keep the oil from thinning out too much. 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. If your car is not an antique or air-cooled, the safest bet is to use a multi-grade oil. The first number on a multi-grade oil indicates the "cold" viscosity of the lubricant, and the second number the "hot" viscosity. For example, a SAE 10W-40 motor oil would have a viscosity rating Viscosity is a measurement of how quickly the oil flows through your engine. Since thicker or higher viscosity oils take longer to flow, it makes sense that an oil with a higher viscosity grade would run more slowly through the engine components. This means that SAE 30 moves faster than SAE 60, for example. ENGINE OIL VISCOSITY GRADES. The word viscosity describes how easily an engine oil flows.
