Mazda bravo fuel economy

hey guys

yesterday i was topping up at the pump and i filled up 38 litres, and that was after only travelling 208kms. So that equates to nearly 19ltrs per hundred kays. This is a 2.6l petrol 4 cylinder......why is it using this much fuel???? I am a pretty considerate driver, dont thrash it at all, and it isnt lifted, tyres arent big (205's or 215's from memory) and it has the normal alum bullbar, sidesteps canopy etc. I dont tow anything or hav a load at the back, any ideas wat could be causing this? thanks

Re:Mazda bravo fuel economy

Sounds like it may have a drinking problem to me :) :)

But seriously - petrol engined 4wd utes seem to have a disproportionate thirst, I have put 40 litres in my previous Rodeo (which was 2.6 petrol) after 250 ks of running around town - Which comes out at 16 litres/100ks. Thrashing it around in the bush was much worse, but I never measured it
So i went into denial for a while and eventully put it on gas just to cut the cost. Gas used to go about 19-20 per hundred, but at less than half the price it was an improvement

Re:Mazda bravo fuel economy

There probably could be a lot of things causing poor fuel economy.

I'd make sure that the brakes aren't dragging (jack up and spin each wheel - might be other causes of wheel drag, too).

Good tyre pressures.

Engine maintained and tuned (a dose of carby/injector cleaner probably wouldn't hurt occasionally).

Wheel alignment?

Make sure that no vacuum hoses have been knocked off (happens a lot).

Re:Mazda bravo fuel economy

thanks guys

i know it needs a wheel alignment and next scheduled tune up is coming up. The tyre pressures are all good. thanks for the tips again. Cyaz

Re:Mazda bravo fuel economy

Re:Mazda bravo fuel economy

WHEN I USED TO WORK FOR MAZDA WE PUT A RESISTOR IN LINE ON THE TEMPRETURE SENSOR CANT REMEMBER FOR THE LIFE OF ME WHAT IT WAS RATED AT BUT STOPED THEM FROM DRINKING SO MUCH. I WOULD SEE A MAZDA DEALER AND ASK THEM ABOUT IT SEE WHAT THEY SAY....... ;D

Holy f#$%......26l per hundred, maybe i should keep my mouth shut lol. With figures like that i'd be afraid to go to the petrol station to fill up

Cheers, i will ask about that when i go for the tune-up. I've never heard about a resistor. What does it actually do? as in how does it reduce the fuel consumption?

Re:Mazda bravo fuel economy

it tells the ECU that the car is actually runnning warmer than it is therefore leaning out the fuel mixture and getting a few more miles out of a tank!!!! ;)

Re:Mazda bravo fuel economy

bravoboy I have a 98 Bravo 4wd extra cab with headers a decent 2 inch exhaust & a unichip. I am regularly getting 8km/l or 12.5l/100k's driving to/from work, must run on premium even though dyno done on unleaded as it pings a bit otherwise. If you intend to hang on to it for a fair while go with a unichip - power up an average of around 25% & no comparison before/after - even sounds good!

Re:Mazda bravo fuel economy

I had a 97 d/cab bravo and had same prob. had inj. flow tested & cleaned. always serviced every 5,000k. checked codes in computer-nothing. someone had told me about the resistor mod but never chased it up. someone also told me of a throttle body mod using xf falcon t/body. i also rang unichip but they said they hadn't had a lot of success with curing prob. In the end I just put up with it until i sold it. its a shame really because i loved the truck did evrything i wanted it to do with comfort to boot. now have vr commodore powered hilux v6 & auto & prob better fuel economy than bravo.

Re:Mazda bravo fuel economy

The car finally had the tune-up earlier this weak and and exhaust manifold leak and dirty fuel filter were found. The guy said the manifold leak probably is contributing to the poor fuel economy so got a new exhaust manifold gasket and a clean fuel filter. He also said maybe a set of extractors might help the problem as long as i dont thrash it ;). So now i'll just keep an eye on it and see what happens, fingers crossed. Thanks again for the help
