D300 fuel economy

Has anyone else found the D300 to be much better on diesel than the D250? Took delivery of the 110 D300 last week and it’s easily returning 36-38mpg, to get that in the previous 110 D250 you had to consciously try very hard, it typically did 28-30.

l can't see how that could happen, but it's great if that's the case. Well, great if you've got a D300.

l can get high 30's from my 90 D250 on a run. With care l can get 40mpg

I've got 27mpg since I got my D250 10,600 miles ago. Eiger Grey MY23 D250 SE with bits. Known as Noddy.

The mapping seems to keep the engine at a lower rev range

My wife managed to do the 🏆 ride with 45mpg. On average she does 40mpg with our D250. I might be a little bit faster on the German Autobahn and do 35mpg.

I have a 110 D300.
We aren't offered the D250 engine here in Japan so I can't compare but here is my fuel consumption.

I've posted in other threads about my numbers and how impressed the fuel economy is, considering the heavyweight spec that I have.

If I stick to the speed limit of 100kmph I can get 15km/l or 44mpg imperial.
