I bought my BT50 2.5L Diesel Dual cab in Nov 2008. In town 10 L will get me 100 km.
My family and I do a 450 km (round trip) for the kids to visit their grannies every school holidays. A full tank (70L) will get us there and back @ 100 km/hr.

I had Diesel Gas fitted to my 3L BT50 as it didn’t have the get up and go I would expect. On a number of occassions 60% of power was lost while towing 1.5T but came back. Mazda could not find problem. After a long trip Perth to Carnarvon & return I had the motor Dyno checked. They found the motor only generating 80kW instead of 115kW. With gas running it was producing 100kW. Mazda have pulled the engine down at my expense as was found only half compression in cylinders. Found scored bores and pitted intake valves. $14,000 repair quote. Investigation is still pending however it has been suggested the gas caused the problem. This voids new car warranty. I would suggest getting a compression check on your engine. Minimum pressure should be 385psi. I was getting between 180 & 200psi on all 4 cylinders. New head gasket alone is $600. I hope your car is still under warranty and you haven’t modified it in any way. Good luck.

To everyone here:

There is one word to describe the Mazda BT-50: inconsistent…….

I bought a new BT-50 and got about 9L/100km on highway (At 160km/H) and about 11L/100km in town….

I have a 2008 3 litre SDX dual cab with 28000 kms. The fuel consumption is excellent. I regularly get 800-850 kms per tank. I did a trip across Australia from Perth to Brisbane, towing a camper trailer with heaps of gear in the tub and generally got around 700 km per tank. I have noticed that the consumption can vary depending on where you get your fuel. In addition, the speedo is way out. When I am doing 100km/hr on the speedo the GPS indicates around 90km/hr. I’m wondering if this means the trip meter is out and mileage is not as good as I think? The standard suspension is crap and has already sagged considerably (the car has copped a bit of a flogging though). Has anyone fitted aftermarket suspension that they can recommend?

Hey Paddy,
I bought a BT50 19months ago new(duel cab diesel 3L)around town with tools in the back get 10L p100km then twice a year i go on a trip (bout 5000k round trip) towing an offroad camper and average about 11.5L p100km also with abit of beach n bush driving thrown in. Did take about 10-15,000km for the economy to even out.Have thrown standard shocks for good after market and ride is less like a wet sponge(that was at 10,000k) Now 40,000km on the clock and runs well. Yes mazda service sucks.Glad it doesnt say the same for the vehicles. Have a read of 4wd action they have been doing up a BT 50 as a tourer and camera support truck.
Also look on there website they do have realworld tests on economy on different trucks.

Does anybody know of a site where we can get a serious review of the fuel consumption of cars [BT-50] tested in the real world?
I’d just like to know what normal people can expect for fuel consumption driving an unloaded BT-50 on the highway at 100kph.
Everyone [where is RACV when you need them?] seems to want to keep this information secret, when it’s really the only thing that we all want to know !

I have a BT-50. Its fuel consumption is rubbish. I traded a Nissan Patrol with a 4.2 diesel, which had none of the fancy engine management, and weighed half a tonne more. It got the same fuel figures, in fact slightly better. Driven like a granny, the mazda can’t get 11k/l at 90kph, empty.
Dealer thinks up all sorts of ingenious excuses to do nothing.
Even tried to tell me it wouldn’t be run in until 100,000km!!
Thinking Mazda: don’t bother.
The service has been lousy.

Just bought a BT-50 08 single cab model second hand at 6000km and can’t get any better then 10.3l/100km, only done 8000 kay so i hope the 10000 service will maybe help that out. Anyone else out there with a bt had fuel consumption lose coming up to 10000 service,hopeing that’s all it is.

My BT-50 is 11 months old. I have just driven from most easterly point to most westerly point of Oz via Simpson desert, Gary junction rd, Exmouth, Carnarvon Gunbarrell & Plenty H’ways, 14770kms & averaged 12.09 litres /100kms carrying a well back camper weighing 850kgs.
But on arrival home I discovered a cracked chassis. Mazda Australia consulted Japan who have refused any claim on warranty because I fitted air bag assist springs to stop the tail sagging under the load. My previous Bravo had the same air bags & load for 55000kms with no problems. BT-50 has 120mm longer rear springs!! funny coincidence that the chassis should fail?? I have heard Bravos had this problem. Anyone else know of same problem?

@ Johnny B.

handbrake is never on (hahaha). Luckily my car was stolen a month ago. I’m once again going to buy a BT-50. ( I love the way it drives :) ) Most people i spoke to about fuel consumption sed they got between 12 and 14 km on a liter. so my car was a dud???

The reason i left my message re the Freestyle 4 cyl was that i was thinking about getting a bt50, as i am a tall boy and would like the extra little room and grunt to tow occasionally without straining…But reading the comments re the above bt50’s im thinking twice…I absolutely love the suicide doors, which lets me get in the back seat and put in things and carry kids without squeezing behind the seats like the other rodeos and others.. This was a deciding factor but like some cars you take more of the plusses and perhaps tolerate some of the smaller negatives..thanks again

Ive got a b2600 freestyle 2005 4 cyl, bought at 29000km. Its my baby and i smother it. Only done 10000km in 18months. ive put it on lpg as all my other cars over the last 23 years no probs. You guys think you have consumption probs, its a 54ltr usable, and despite gently accelerating and good maintenance, im getting 20LT PER 100km on gas…Pathetic…the worst was towing a 4.5m tinny.On highway cycle it was even worse, gently cruising but taking into account extra weight etc.. i only managed 25LT per 100 km !!! Based on formula of mileage = consumption divided by distance..cleaned O2 sensor, vehicle tuned and maintained…Thats worse than my old babied 10yo triton that got me better mileage.No one can help Whilst i accept diesel/unleaded are different fuels and gas has a lesser tolerance in consumption, im still disappointed… Any ideas…thanks

Gabriel – I have just returned from a 1200km trip to central west qld towing the camper – worst consumption just over 12l/100km. SDX dual cab has close to 40,000k’s up now and I have had no worries with it other than crap tyres fitted as standard. If I were you I would either get fair up Mazda or check your handbrake isn’t on!

@ AeroKits & trent kempster. I bought a BT-50 about 7 months ago. my fuel consumption was a nightmare. I got 6.8km/L in town and 4km/L on the highway!!!!! (Thats about 480 km on a 70 liter tank in town and about 280 km on the highway driving about 160km/h). So thats 13.5L/100km town an 23.2L/100km highway. Mazda SA sed my BT-50 was in spec? thats one hell of a spec don’t you think?

Aerokit – are you getting litres per 100km confused with km per litre?? I regularly get 8.9 – 9.4 l/100km in all conditions. Worst I have had was 12.2l/100km towing 1000kg camper trailer over 300km and including some serious playing in the sand dunes!

9.2l/100km is equiv to 10.87 km/l. Formula is: litres used/km travelled x 100 = l/100km
