I've tested it in my Civic and Odyssey. The results were similar. Drafting (3 seconds back) gave about the same benefit as driving ~6-7 mph slower.
I like to give myself enough space to stop if the truck was suddenly not moving at all. My car's stopping distance = my drafting distance. Let's say that's 150 feet. At 60mph, that's about 2 seconds back. Only time I'm closer than that is when they pull in front of me.
My highway advice:
Manual trans - P&G. 45-60 mph P&G is worth about 70 mpg in my civic in good weather
Automatic - DWL. 60 mph DWL in the Odyssey is worth about 29-30 mpg. (rated 18/25 old, 16/23 new)
