Blatantly plagiarized from Wikipedia:
"The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating they are "winter" (not "weight") or cold-start viscosity, at lower temperature. The number 20 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade. The document SAE J300 defines the viscometrics related to these grades."
not accusing you of anything but trying to make a simple thin more complex than it needs to be, ok we get it you are a very smart guy. a lot smarter than us who call it weight. but guess what, we don't care and have fun with your science.
May be a dumb question..
Why Mobil 1 Racing have 0W-30 and 0w-50 normally if 0W are for winter why use it in racing engine,most racing car are use during warm weather...
