Hey everyone, we have owned a rodeo dual cab v6 3.2 ltr for just over a year now. bought an older ute so we can throw all the camping gear in the back. Never realised how bad the fuel economy was on them or i wouldnt have bought it.
Been reading on a post on this site about resetting the ECM which I am going to try on the weekend but there was also a post on changing to a finer filter air cleaner element. Not knowing a whole lot about cars I wanted to know if this is a brand or a type of filter? Is it something that can be bought from somewhere like supercheap or is it more specialised? I am desperately trying to fix this problem as we are going to have to sell the ute becasue we cant afford the fuel. currently its only getting 350 ks per tank if we are lucky.

I've got a 2003 RA rodeo with a 3.5 litre v6 petrol and they are a bit thirsty and I get 16 litres per 100 km but mines also on LPG and get 18 litres per 100 km out if the LPG

LPG though is approx 33% cheaper than diesel ....and petrol is also little cheaper than diesel
Do your home work and work out the cost to travel. 100 km at your fuel consumption on your petrol rodeo at your local petrol price and then do the same with say an early example of a 2000 model diesel dual cab that say would get approx 12 litres per 100 km also at the current diesel price and look at how worse off you are off per 100 km
Then do your sums to work out if it's justified trading

Also don't go for finer filters stick to the standard air cleaner
Big tyres and roof racks will add to increase in fuel consumption

Hope that's of some help

Also check your tyre pressures
Roof racks, big tyres, tyre pressure all add their little bit
Also take care with the right foot:/)
Forgot to say mines an auto and try to always keep it under 2200 rpm even when taking off

Ours is also an auto and we are definitely not lead foots, no roof racks but it does have a canopy, tyre pressure good and tyres are the standard ones they come with.
I think the tank is around 70 ltrs so working on that it gets between 18 and 21 ks per 100 ltrs. really need to try and improve on this, but am bit hesitant in trying much when reading posts on here that say most mods dont do much.

Whats wrong with the finer filters out of curiousity?

I worded that wrong
Some surgest to use these K and N filters that allow better air flow and breathing into the motor
Which I believe they do.... But always feel there's a trade off with how well they filter outer fine dust particles
The trade off May be these KandN filters are fine for bitumen driving but swap over to your std paper air cleaner when hitting the gravel roads

K and N filters work well but being oil soaked some will get on to the sensors downstream and give you worst fuel economy. You don't say if your ute is manual or aoto. 18 to 22 is normal for aotos but shold drop to 13 on longer trips. My son has got as low as 10.9/100 out of his manual jack sitting on 90 on a trip. Around town manuals should do 15/16 per 100. I get 400 ks to around 65l around town in a heavy wide track 03 SE Jack.

leanne, had a look around some forums via google (3.2 v6 rodeo fuel consumption) and consumption appears to be a common problem reported.

Some of these threads might have a few tips in there . . .

These might also give you the overall picture if it is worth pursuing to get the econ better, just might not be possible to get to a figure you need.

350km from a tank, how many litres at fill up average ?
Have you kept track and know your litres per hundred ??

From what I know it's getting between 18 and 21 litres per 100 ks, so any improvement would be good. I think the tank is about 70 litres, hubby usually fills it so I never look!!!

Yes, very high, but not uncommon figure looking at threads around.
Be sure though not saying 350ks done at fill, 70lt tank, = 20lt / 100km.
Apologies if your hubby already does this, but you should record km / lt at fill (eg. say 360, fuel put in to fill 63, divide 63 x 3.6 = 17.5lt / 100km.
Do this over at least 3 or 4 tanks and on, and you get very accurate fuel averages used.

Finer filter would likely restrict air intake.
Probably the first thing most people do to improve performance and fuel econ, is 1. Get more air into the system (and cooler if possible), adding a snorkel for example, and 2. Get exhaust gasses out faster, typically by upgrading exhaust to larger dia, or better flow mufflers.

Those aren't cheap mods, so might be better to trade / sell, cut loses and look for a nice little diesel CR dual cab.
This would be about the only way to ensure you get closer to 10 - 12lt per 100.

Any mods you do will only decrease fuel consumption by maybe only 1-2%, don't believe these 10-15% as you will be very disappointed.

So in the real world you might spend $200+ on so called fuel saving modes that may only save you between 25 -50 cents per 100 kilometers.

At 40,000-50,000 kilometers you might be a break even point.

350k per tank is about the norm, they were not renowned for the fuel efficiency.

thanks for that, not good news by the sound of it. Wish I had known before we bought it about the fuel. From my estimates we are only getting 18- 20 ks per 100 lts so really need to try and improve this

G'day Leanne,
That sounds about right for the V6 3.2.

I had one as a company car many years ago. When travelling to Rockhampton from Bris, from a full tank in Bris, I had to refuel at Tiaro to get to Rocky.
Disgusting economy from it, the company replaced it soon after.

Poor fuel consumption iin the 3.5 V6 is often related to oxygen sensors Leanne, not sure about the 3.2. Iirc aftermarket sensors aren't expensive. Might be worth googling and/or having checked.

Hi Leanne,
Before anything else is tried take your rodeo to an experienced auto mechanic and have it thoroughly checked over.

Have them replace the aircleaner element with a new one, replace the 6 sparkplugs with ones that are correct for the vehicle, check the ignition timing, change all oils and replace with recommended oils, check that the brakes are not dragging and that the handbrake releases completely, replace the airflow sensor and check that the tyre pressures are correct.
Check that any airhoses do not collapse inward when accelerating.

Check that the exhaust pipe has not been flattened somewhere underneath.

Any/all of these issues will have an adverse effect on the fuel consumption on a model that was not renown for great economy.

That Rodeo V6 motor will do a lot of K's before it is bugga'd (3-400K km is quite common) but they were never a light motor on fuel 16/18l/100km is average.

Hope this helps.

We have a Jackaroo with a 3.5 auto.
The engine may or may not be similar but the lack of fuel economy is.
We had a fair improvement by allowing the exhaust gasses to escape faster.
With the 3.5 litre there is a baffle in the exhaust near where the Y pieces join before the cat converter.
With this baffle removed and a higher flow semi sports muffler fitted we gained around 5% to 7% better economy but that was never calculated accurately. 3 years ago that was a $275 total job at an exhaust place.
The car felt more responsive in acceleration and we were getting an additional 30 k's per tank before refuelling around the quarter tank mark.
One fault was the exhaust noise had increased and tends to drone on long runs.
We also fitted a snorkel, but there was no noticeable "feel" of improved performance or better economy.
There was plenty of information on Jackaroo's on the Club Isuzu website, and I would assume there was info on Rodeo's but I have never had the need to look at it.
I wish you luck
I'll get there someday, or die wanting to.

On the matter of air cleaners.

In general 4wds have oversized air cleaners and air cleaner restriction is not an issue.

On the matter of after market air cleaners in general.

There are a lot of people who want to sell you an expensive air cleaner.......On modern vehicles the factory standard paper air cleaner is perfectly adequate and there is little or no improvement available in the factory housing with out compromising filtration efficiency and therefore allowing more crap past the filter to wear out your engine.

There have been many properly conducted tests to prove this.

THE best thing you can do is make sure your air cleaner is clean....either by cleaning it or replacing it with a factory standard type paper filter or a reputable brand.

I agree completely with Disco..reply 6. Before spending anything on so called economy
improvers, follow that advice to ensure the motor is operating without impediment.
As a long time owner of a Jackaroo V6 Auto I can vouch that these motors like a drink,
but, if driven for economy, reasonably acceptable figures can be achieved. Anything over 100kph will see economy plummet. I can achieve the figures you quote while
towing our poptop, & get at least 15L/100 without it. The difference berween 110+ &
90/100 is a whopping 30%. Get it tuned correctly & lift the foot..you may find you still
have a car worth keeping. Good luck with it..cheers....oldbaz.

My sons 2004 Petrol Hilux is exactly the same. Having said that paid nothing for the car and it is reliable and servicing costs are fantastic. Given what he paid and the cost of ownership happy to pay for the fuel until such time he can afford a better car. Recently replaced his tyres with some Yokohamas and it improved slightly. For long trip he borrows my Diesel Hilux so all in all we accept it for what it is because it is so reliable. I would not throw money at a 2001 Rodeo chasing better fuel economy I would be looking to replace it if you need to do miles and want lower running costs.

Another thing to consider is the actual cost of fuel consumption.

A lot of people get realy narky about small changes in the fuel price and relativly small diffenerences in fuel consumption.

SO...what is the actual cost of this fuel consumption....AND compared to other expenses and costs of motoring.
