Yeah, 60mpg - good innit?!
Most XTs seem get around the 60mpg mark. I get up to 68mpg if I'm in a fairly chilled mood at say 65-70mph on dual carriageways or pottering around on back roads. When I'm in the groove and giving her the beans that'll drop to about 53-54mpg.
I've now covered 4000 miles on my 2009 XTX using 305 litres which (at 4.546L = 1gall.) gives an overall consumption of 59.6mpg. I'm suitably impressed with that!
Petrol out here in Gloucestershire is around 132.9-133.9p at the mo.
