GL4 and GL5

[printhead at usinternet.com]

The information on this link is kind of promotional toward Redline
products, but the explanation of the difference between GL4 and GL5
lubricants is pretty good.

My favorite place to get Redline products is Pegasus Auto Racing Supply.
Good down to earth people to deal with. Orders have always arrived
promptly for me.
