Hi,
I would like to hear from other Mazda Bravo/Ford Courier Turbo Diesel owners as to what fuel consumption they get. I have a 2000 Bravo cab plus with a steel tray and canopy for camping.
I have just returned from a 3 week camping trip along the Murray river, just road work and no 4WD. The overall fuel consumption was 12.8 litres/100km (22mpg)
I travel at no more than 100km/h on highways except for rare occasions and most of the travelling was just on ordinary back roads.
I have heard people talk about 9litres/100km. If only! I have never seen better than about 11l/100 under any conditions since new.

I wonder if there is some problem with the injection timing because the engine seems to run out of puff much over 3000 RPM and I feel that it really drinks like crazy at higher revs, such as highway cruising.

Anone with experience in these things?

Phil

Phil,
My 2002 Bravo TD cab plus returns about 25mpg around the suburbs & outer metro driving. Doesn't seem to change much on the hwy, maybe up to 26/27mpg if I've taken it easy and cruised along at 90-95kph. I presume you were loaded up fairly well on your trip - that will probably have some effect on consumption.

cheers

That still seems better than what I get. I was not really loaded up. Probably only 300Kg over the empty weight without canopy. However the empty weight is almost exactly 2000kg, as measured on a weighbridge and this is quite a bit over the empty weight of the Cab Plus with a ute tray. Steel trays are heavier than I expected!
Last year I got the same consumption, 12.8 l/100km, coming back from Broken Hill at 100km/h, and there are no hills on that road!.
25mpg is about what I get for local rural running without canopy.
I have no real complaints about performance. It can sit on 110 on a freeway without problems and still have more for passing if needed.

Maybe I should get the timing checked. Cleaning the air filter made no difference to performance or consumption.

Cherrs, Phil

Phil Don't be too concerned as the figures you give don't come into the "very high" consumption category in my opinion. I have a 3lTD Prado and mine are similar. Unloaded on the highway it's 11l/100. Mix of highway and city is 12.5l/100. All city (I have just refilled after 1,145km all city) is 13.49l/100. Off road in mountains goes up to 15l/100. Towing a 17ft van Melbourne - Merimbula and return was 15.6l/100. This was on cruise control at the speed limit - mostly 100 but 110 in parts of Gippsland. I was very happy. Don't take much notice of people who say "It never changes" or "there's not much difference no matter what I do". What they are really saying is, "I don't monitor my fuel consumption very accurately!!" Fuel consumption is directly related to the amount of energy required to move your vehicle. Admittedly diesel consumption doesn't vary as much as petrol but it does vary. You have a canopy - that will cost you fuel. So too will a load. Running out of puff at about 3,00rpm is par for the course for a diesel, but you have plenty of puff when you climbing steep grades in low range at 1,000rpm. The petrols are spinning at 2,500rpm to get the same torque - hence the diesel is more economical when the going is tough.

I run a Triton 2.5td which is a little different but can assure you that a tray about 6ft wide protruding each side of the cab & a canopy above that will surely drop your km/l.
Wide tyres will do the same.
I would expect your motor to spin to over 3000 rpm as its rated kw is higher than the Triton for same capacity.
Does it blow black smoke to any extent when taking off?
Has the injector pump timing been set to the optimum?
Have you tried leaning off or enriching the mixture?
Too lean & it wont get up to speed & too rich & it bogs down a bit.
With a few minor changes my Triton will easily spin over 3500 & tops out at 140kmh on a good day not that I use that.
It is a ute tub with a slipstreaming canvas top & does 10-10,5 km/l at 100kmh
and at lower speeds around country town taken easy does the same.
Will hold 100+ on long highway hills.
Hope that may help. Maybe a check on the ford/mazda section on outerlimits 4x4
will help you.

Hi

A friend of mine brought a Bravo TD and it wasn't going very well, turned out to be sucking air through the intercooler, might be worth checking.

Haven't asked what fuel economy he is getting

Hi phil

I have a 1999 Courier td and have just returned from a trip via Bourke, Tibooburra, Innamincka, Cordilla Downs, Birdsville, Marree, Arkaroola, Wilpena - 3000kms dirt , 2500 kms tar and a couple of 100kms bush tracks. I was towing a 1750 kg off-road caravan and have a canvas canopy, aluminium tray and roof rack. My overall average consumption for the trip was 16.1 litres/100km. Around town without caravan and canopy I use about 12-12.5 litres/100kms. This is pretty standard for Couriers which are known to have a higher consumption than Rodeo/Hilux. They make up for it in ride and comfort - it handled the trip with ease.

I have no problem cruising around 3000 rpm and regularly get up over 4500 for overtaking, towing up hill in lower gears etc.

Hope this helps.

cheers

Dear Trracer,

Thanks very much for your experiences. It sounds like what I get is par for the course. What had me wondering was some reports, including on this forum, of consumption around the 10.0l/100km mark. Maybe they were kidding themselves!. Incidentally I checked my speedo and oddometer and found them to be very close to correct. Well within 1%. For example the radar indicator on the Hume Freeway south of Woodonga read 109km.h and the speedo was just below 110. I have 205R 16 standard tyres which are fairly new. I agree that it is a comfortable vehicle. The ride is good and the seats I find excellent with good back support, at least the Bravo ones are anyway. The Courier are different I think.
I have a steel tray which might add some drag. It certainly adds weight. With the tray and full steel bullbar it comes to exactly 2000kg with full tank and me in it. Thats about 350 Kg over the ute back version.

Thanks again for your response.
Phil

Phil

My courier is a dual cab with a 130l tank and I was carrying about 400kgs of gear on the trip which brings it up to about maximum weight with the caravan (3850kgs in total) so consumption shouldn't get worse than this. I also found that consumption improved as the trip went on so perhaps they have a long running in period (started at 17.3 and ended at 15.4 l/100kms in similar conditions).

You mentioned that you have 205R 16 standard tyres. We travelled with a Bravo for half the trip and he had 3 punctures on the Strezlecki with similar tyres. I changed to bfg 225 75/R16 A/T KOs and had no puctures on the whole trip and a much more controlled and comfortable ride.

cheers

I've got 225/75 16 BFG all-terrain KO's on my Rodeo and they're 50000kms old. I have never had a puncture and they look only half worn.

They are the best tyres I have ever had.

Utemad.
