We get 21 to 22 out of our Shogun, if their is a head wind down to 20, l agree a little more thirsty than other 4x4's but will take that for the reliabilty we get from the Shoguns we have had before, mind you this is the first Auto we have had the others being manual, what a difference when towing "brilliant".
One thing make sure at the service they clean the breather pipe on the turbo, if it gets blocked engine management puts it into crawl (which is no more than 25mph) until you have it cleaned out, happened to the wife, luckerley we have recovery who sorted it out, told us if its cleaned on service every twelve months you will have know problem.
