Increase Fuel Efficiency on 4.4 - Funny I know!

I wanted to inquire if anyone has found some good tips to increase fuel mileage on their x5(4.4 preferrably)? Has anyone tried hydrogen kits?

For me using cruise and not touching it helps on the freeway - we got up to 23mpg on a road trip, as well around town not flooring it everywhere - takes all the fun out of it though!
