My claim, and most others I'm sure will agree that a mixed 30+MPG is possible, but that in turn depends on what mix. My point was that improving your own and the cars driving behaviour is the only effective way to achieve a 30+MPG mixed. The gentler driving style with a 'light-boot' will use less RPM will use less fuel - its really more a question of what I / me / now / can do, get into the habit of doing that 365 days a year and you are on a winner.

In town you can't really use cruise, other mixed driving you can and should use cruise, cruise [the puter] not only knows better than you but can change several thousand times a second and make adjustments. Try it .. .. do 30 or 40 or 50 MPH without cruise and the same speeds with cruise you will find you (1) do any speed with a 20+% reduction in given RPM for the same speed [reduced fuel volume cost] and your (2) gearbox changes up earlier more reduced fuel volume cost.

In additive / chip-MOD terms I've never had a lot of time for the alchemy it promises. I can see that blanking the EGR which needs a re-MAP [see #18 ] will help fuel across all RPM and lifestyle uses. In short there's nothing much that a 'school run only' style use of a 2.8CRD can do to improve MPG but we all knew that when we joined the Voyager army. There is however a lot we can do on mixed and above driving .. .. starting with the right foot.

Best of luck Timmy.
