SAE (Society of Automotive Engineering) 20W is a quality (viscosity) of oil.
SAE J300 has established eleven viscosity grades, of which six are considered Winter-grades and given a W designation. The 11 viscosity grades are 0W, 5W, 10W, 15W, 20W, 25W, 20, 30, 40, 50, and 60. These numbers are often referred to as the 'weight' of a motor oil.
The lower the viscosity grade, the lower the temperature the oil can pass the standard test. For example, if an oil passes at the specifications for 10W and 5W, but fails for 0W, then that oil must be labeled as an SAE 5W. That oil cannot be labeled as either 0W or 10W.
√(w+20)=4 Square both sides: w+20=16 w= -4
If you mean 20*w=6.5, then w=.325.
w = 5
If you meant 3 20 as in 3/20 then it would be 0.15
IF you meant 75 percent of 20 - the answer is 15 !
20W-50 is equal to Sae 90 W.
The 'W' stands for WINTER. It does not stand for weight. What would the oil be weighing? 12oz of 10w-30 weighs the same as 12oz of 5w-20. It is related to the cold temperature viscosity of the product. A multi-viscosity oil, 5W-20 for example, will perform like an SAE 5 product when cold and a SAE 20 product when hot. And as a bit of additional info, oils are not 'weighted' they are graded. SAE grades the oil.. SAE 5, 20, 30..
SAE 5W X 20 WEIGHT
The owners manual shows SAE 5 W - 20 for the 4.6 L and 5.4 L engines The owners manual shows SAE 5 W - 20 for the 4.6 L and 5.4 L engines on a 2001 Ford Expedition
According to the 2001 Ford Ranger owners manual : The 2.3 L and 3.0 L take SAE 5 W 20 The 4.0 L takes SAE 5 W 30
SAE 40 has a higher viscosity.
SAE 40 has a higher viscosity.

There should be a decal under the hood with the specified oil for your vehicle. My 2000 Ranger recommends ASE 5 W 30. --------------------------------------------------------------------------------------------------------- The owners manual shows :( 2004 Ford Ranger ) for the 2.3 L and 3.0 L - Motorcraft SAE 5 W 20 Premium Synthetic Blend Motor Oil ( U.S.) and Motorcraft SAE 5 W 20 Super Premium Motor Oil (in Canada) * ( the use of synthetic blend is NOT MANDATORY - you can if you wish ) * for the 4.0 L - Motorcraft SAE 5 W 30 Super Premium Motor Oil
0w20 is a designation of the weight of oil. The 0 means it flows easily at cold tempertures. The 20 means it becomes a 20 weight oil at full operating tempertures. The w stands for winter.
The numbers in a lubricant's SAE (Society of Automotive Engineers) rating represent its viscosity at different temperatures. In the case of a SAE 20W-40 oil, the number before the 'W' (20) indicates its viscosity in colder temperatures, while the number after the 'W' (40) represents its viscosity at operating temperatures.
