BT50 / Ranger fuel economy?

Joined: 30 Dec 2002 Location: Adelaide

Has anyone with a 3.0l turbo diesel BT50 or Ranger worked out their fuel economy?

A relation has recently bought one (SDX dual cab with 5 speed auto) and the economy leaves a bit to be deisred compared to the window sticker/ claimed figures by Mazda. Roughly it's using 15 litres/ 100km.

I've got the XLT ranger in auto and i'm around the 15L/100 also, and that's with the ute empty.
My 2wd ranger which carries close to a tonne all day every day gets around 9L/100.

Is your 2WD the same 3.0l engine or the 2.5l?

I warned them when buying not to expect the claimed figures (windscreen sticker and brochure said IIRC high 9.xl/100km, Mazda website 10.4l/100km), but 15l/100km is way off the mark. It isn't getting driven hard from what I've been told either.

He's not impressed given the salesman also said it would get around 10l/100km.

The 2wd is the 2.5 manual

I was expecting a couple of litres above the sticker, but not around 5.
Seems the manual 3lt is the way to go for economy, i think the stall converter in the auto is a little to high.

I've just discovered that thread on 4WD Monthly, it seems a few auto owners are doing significantly worse than others for economy. Confused

Out of interest I did some data logging using an OBDII interface and software on my laptop yesterday. We went for a 10 minute drive around the suburbs (nothing overly spirited, just going with the flow mostly) and averaged 27l/100km Shocked

going by the software.

It's going in this week and they're going to have a look at it. Even on long trips it's using over 15l/100km.

An update. The software I was using for datalogging apparently won't work for diesel engines, it was only giving a figure because the BT50's use a MAF meter (but of course diesels run at a different AFR so the calculations will be all wrong.)

Anyway, it went into the dealer during the week and they were told there were recent software upgrades to be uploaded. Apparently the auto trans shifts a lot better now and it seems to drive better, but only time will tell if the economy has improved.
