SD4

Hi i got my FL2 sd4 delivered today and i have a bit of a blonde question.On the obc when checking MPG it gives a AVG MPG it also gives INST MPG what does INST MPG mean please ??

INT means instantaneous. So you actually MPG at that moment, which is updated every second.

Is that on a run or just local

Just local, nipped to Asda last night just on the A roads, drove it sensibly & the “Instant Fuel” reading hovered around 40mpg when it was in top gear

If yer want to know what it will do at each speed... get to that speed, trunk on cruise control, reset the trip, continue for about a mile and the average mpg will then update. This is far more precise than the instantaneous reading. You will find better mpg at 60mph than 70mph as an eggsample. Don't ferget to watch where yer going.

Better mpg using your foot rather than cruise

You can get readings like this with the ingenum engine and nine speeder, and that’s average, not instant !

Yer but no but some can't keep their feet steady to reduce the oft set of hovering acceleration. We also have a few imbreds on ere with webbed feet

Yer but no but it's not a Freelander so it will never be as good

The Ingenium is a great engine - and you might get an average 60+ on some journeys, but I don't think you can really expect average MPGs of 60+ in any cars that it will go into.



That was my brother's Jag XE 2.0D R-Sport. But the Equa index shows 42mpg for this car.

Here’s an sd4 with six speed box on a comparable journey to my earlier post, when tank gets down to halfway you can take about 15 mpg from that figure, it’s just not sustainable in everyday driving
