You can save that and more by just driving more conservatively or slower.

As been said, the difference between planting your foot at the lights or keeping in a economic speed band on the motorway could save your 10MPG+.

Anyway, a proper remap costs €100's so anything on DoneDeal for €50 is literally a resistor in a box.

The MPG tuning costs €150. Conservative driving is all well and good but how many actually do it on a regular basis. You might do it for a day of two and go back to your normal style. Also circumstances out of your control might lead you drive more "aggressively". Also I have 1.9 diesel, there are times when I have to drive the stones out of it to clear the dpf.

before you go for an MPG remap, make sure you've got the basics covered as they can yield very noticable margins if neglected:

• Tyres: Keep your tyre pressures at the recommended levels
• Weight: Remove any dead weight from the car. (boxes, bags, lumps of metal, etc. that are on the back seat or in the boot)
• Oil: Make sure your Oil has recently been serviced (as per manufacturers schedule and guides)
• Air Filter: make sure that's clean. If you live in a city or drive dusty roads it will clog sooner - your engine will hence have a hard time breathing
• Brakes: make sure they arn't sticking. Just make sure the brake pads wings have some copper grease, and that the sliders have a bit of red rubber grease.

They're all pretty simple things to do, and they all affect your MPG quite significantly.

What year is the car, and what kind of MPG are you getting at the moment?

Some good tips there Sebastian, thanks.

Good, then you have a choice. Load up the wife-and-beasts and set off at about 8am some fine Saturday morning for either the Ring of Kerry or Dublin. Drive the ballacks out of that thing, have a nice bit of lunch and some shopping or whatever, then drive the ballacks out of it back. Live long, and prosper!

It is. And it would be a much more pleasant and productive use of your €150 than finagling the DPF and ECU in that thing, when all it wants is most likely a bloody good thraping.

That "thing" as you so kindly put it has got plenty of "thrapings", we've been to the west coast of Ireland twice in the last month and that hasn't improved it.

Has the fuel consumption disimproved since you bought it? Does it smoke?

Diesel is like petrol really.

Its great on a long straight roads when its serviced and well looked after.

Twisty roads,town driving,school runs make terrible mpg whether your driving a petrol or diesel.

That's the problem people don't see and think diesel is a wonder fuel.

Take a 1.6 petrol and a 2.0 diesel, drive them both around town, twistys and to schools. You wont see a vast difference when you take into account tax and the extra cost or servicing a diesel plus when modern diesels go wrong there expensive to fix


So unless your putting up big mileage petrol is better.

Maybe your doing to many short runs and that's probably messing up your mpg

Fuel consumption has been the same since we have had it. No smoke and it is well serviced.

Maybe you are right kwacker. Maybe I was too optimistic about a 1.9 diesel . Too be far we don't too many sort journeys, mostly motor way driving.

Your mpg should be pretty good so!

Is the jeep constant 4 wheel drive?

Check out a Suzuki forum and see what others are getting.

Some diesel engine's are just heavy on diesel and made more for pulling power that cruising say.

Yeah it's permanent 4 wheel drive (40/60) split. Most of the forum chat is about getting mid/high thirties, so I'm not too far off. Bit of chat too about removing the dpf filter to improve mpg too.
