MPG Question

Hi all,

Just bought a new Doblo Cargo SX 1.9JTD. Really nice vehicle but:

Fuel consumption is not quite what I'm expecting. Around town I'm getting about 38mpg (unloaded), and on a 2,500 mile run to Europe last weekend we were getting about 30mpg loaded and unloaded. Aircon seems to make maybe 2mpg difference at most.

Just seems a bit heavy on the fuel.

Anyone any ideas?

Tin

Re: MPG Question

Hey Tinman,

Welcome to the forum. Ozzie will give you the official welcome but I guess he's still got his jimjams on and his mummy is letting him have a lie in.

How are you measuring your mpg? What speeds do you travel at?

Re: MPG Question

speeds in europe were generally around 80mph.

strange thing was that even when were cruising higher than that - fuel stops came at very similar intervals.

i've done a bit of reading around on the forum and a few people have said that their fuel consumption only started getting better once the engine had done over 10k.


(if anyone ever sees my old Bravo, (part reg number W122), 100sx, 15" fiat alloys, big fiat rear spoiler, black - tell me. its one car i would love to get back. should never of got rid of it 3 years ago).

Re: MPG Question

50mph is the best speed for high mpg, it will use 35 - 40% less than at 80.

Re: MPG Question

50mph probably isn't best when we have to do 400-600 miles per day in Europe on motorways.

There might be an increase as the engine runs in a bit.

Re: MPG Question

Hello Tinman and welcome to the forum

Niall I was in work actually plus mummy doesn't let me have lye in's

Right now to the point at hand... You will see an increase in MPG as the engine wears in a bit, and that will continue for a few thousand miles. If you have one of the new engines (I think they're called multijet or something similar) then you won't get quite as good MPG as in the older 1.9JTD's anyway for a while as they seem to take longer to reach their full potential.

Doing around 100mph on the motorway I return about 46mpg, doing 70 I return about 60mpg and town driving if I'm going carefully and not flooring it I can get around 55-60mpg. This is on an engine that's done 22,000 miles usually wit 2 - 5 passengers. I don't see no difference when it's loaded up personally but I only carry 200-300kgs max so I probably wouldn't.

Also don't believe the Trip readout on the Trip computer as it's usually about 3-5mpg over what I'm actually getting. Best thing to do is a brim to brim check

Re: MPG Question

It's not bad, and also wind plays apart but I get a lot more and so do other people with Doblo's

You got a 1.9JTD Alex?
