What is your regimen?

I have found that reading, understanding, and following the owner's manual always works best!

That is good advice unless you know that you did something well outside of normal operating range. One tidbit that I have found in two of my manuals that does not seem to be widely followed is to put the transmission in neutral if you are going to be stopped for several minutes to reduce heat buildup.
