I know Mr. Yount, JT, and some others posted in it and it was quite informative... Enlighten me and others...What do the numbers relate too?

In multi-weights, the first number (5W, 10W, etc) is how the oil flows when it is cold (32*F). The second number is how the oil behaves when it is hot (100*C/212*F). So a 20W-50 will flow 'no thicker' than a 20 weight when at 32*F and will not thin out more than a 50 weight at 212*F. I see big plans are in motion. I hope parts are coming in.

5spd GT "the 5.0 owns all" Founding Member Aug 7, 2002 9,516 6 99 Arkansas Feb 2, 2006 #6 Feb 2, 2006 #6 So what does the "weighted" number come from. It's just a scale I guess or does it mean more... Basically I'm wondering (for a lame example) does the 5w mean it takes 5lbs of pressure to go flow a certain amount at 32F? Thanks for the replies...very helpful!
