2010 TDV8, perfectly maintained and low mileage (30k) and I did a 1,000 mile round trip to Ireland over Christmas. Mainly motorway miles (75%) and I averaged 25.6 mpg. In town I get 17 mpg or so. I've never seen an average for any journey above 30 mpg or even that close to it.

Mine was a 2007MY owned for 3 years from new and Part-exchanging it for the same engine in a FFRR was a huge mistake as the same engine in the 2010MY FFRR was no where near as good as the RRS's one and the after the Brembos of the RRS the piddly little non Brembo brakes on the FFRR were dangerous ................ Maybe I had one of the better TDv8 RRS's, I had to drive in town (which I rarely do) to get the sort of figures you guys are talking about in the RRS. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced
2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Sub 22mpg for a TDv8? I struggled to get mine worse than 28mpg and then I had to be playing total idiots all day off-road in low box and wellying it. On motorway steady speed runs at 70mph on acc I could often see 36mpg on my 2007 and 2010 3.6 TDv8's, one was an RRS and the other a FFRR Vogue

I'm with RRSTDV8. Now done 13600 miles since purchase in March 2016 and overall average is 25.44mpg includes two trips SE to Aberdeenshire (1300 and 1800 miles) and some 80 miles round trips (say once or twice a week average) and the rest more local trips of a few miles. I'm mostly a pretty relaxed driver but with the occasional blast (or why would I have bought a V8?). Robin

We are getting a little off topic now

I suppose to see if it's a viable option to keep/sell/repair, we need some figures...
