Thanks for the info, Pedro.

I believe we have 75 litre gas tanks and I get pretty close to "Empty" at around 62 litres. With that, when I'm driving easy, I get 420 km. That works out to 19 miles/ imp. gal. (16 miles/ US gal.).

Your diesel would get 100 km/11 litres or 25.7 miles/ imp. gal. If you got 100 km/10 litres that would be 28.2 miles/ imp.gal. (23.5 miles/ US gal.).
That's pretty awesome.....50% improvement.

By the way, I like the looks of your European Ranger.
