I run a 91 Vogue SE, it's on 235/70 16 Mud Tyres, it has a snorkel and light bar and the front spoiler has been removed so it isn't exactly what you call configured for minimum drag. I estimate I get an average of 15mpg. 10-12mpg on a day laning and about 23 -24mpg steady 75mph on cruise on motorway.
