600w............enough is enough!

[1931 flamingo]

I don't know, it just amazes (bothers) me that everyone wants to re-invent the wheel. Reliable suppliers to this hobby have gone out and given us 600W (I don't care about it's chemical make up, viscosity, characteristics, etc) in a convenient, easy to use bottle that's relatively inexpensive. Use it. MOST of us probably don't drive more than 1000-2000 miles a year. If you'd changed and put "some kind" of fresh gear oil in your trans and rear end, the lubricating qualities are going to outlast probably all of us. Sorry for the rant. As Bill says the "search" function is a valuable resource.
