3000 V6 fuel economy

[krokkie]

I am currently getting +/- 5-6 km/l in town and +/- 7km/l on the open road.
I did not buy the Pajero for economy, but is there anyway of improving the fuel economy?

biking to work.

Reminding yourself how much cheaper it is compared to the 3.5. While this may not ease your wallet or your fuel tank it may ease your mind.

Remember that it's how you drive it that is the biggest cost saver (I saw it on Myth Busters) also try using higher octane fuel, although the fill up cost is higher, you have more available power and thus you don't have to accelerate as much to achieve the same speed, you may find that it saves you money (as long as your right foot isn't too heavy)

I am using 95/98 octane.
Will cleaning the airflow sensor or replacing it make any diiference?
How about a K&N airfilter?

[yorick]

One of the best things you can do for a solvent burner fuel economy is a good set of extractors. Beats the hell out of anything else other than the aforementioned mad pedal application. Of course as well as widening yer torque curve they have other upside of increasiing your power.... of course to prove that, requires greater application of the aforementioned Mad Pedal and hence..... well you get the picture!

[krokkie]

Thanks, but I'v never heard of extractors?
Are they easy to come by?

If the airflow sensor is dirty then it's worth cleaning it just in case it helps.
A freeflow filter will only help top end power, it'll do nothing for part load economy and won't keep much dust out your engine either.

Also known as headers. This is a plumbers nightmare hanging off the side of Mercutio's 2.3 -16 190E Mercedes Cosworth motor.


Should be able to find a tuning shop around that will be able to source for a 3l Mitsi. Pretty common motor.

[krokkie]

Thanks, i will have a look.
Does the Pajero have a catalytic converter and can I remove it?
Will it make a difference?

Yes, yes and possibly. If the wagon has done 200k plus it's probably clogged up and not working anyway. Performance probably won't change, not detectably, and the CC is only one part of the whole emissions control process, which is said to contribute to bad fuel economy, with modern motors though I would be doubtful that the difference is detectable unless it's pre '90ish, then I think it may benefit.

Bloody hell!!!! I thought the 4l Jeeps were expensive to run.......!!!!!!!

[krokkie]

Thanks for all the help.

Heh, V8 territory to be sure, but it's about the same as a 2250 landrover and if it's up in the k's it's not that out of the way. The problem is that Fuel economy can go to hell in a handbasket for a whole lot of reasons from Tyre pressures, to drive train drag including brakes and badly adjusted carden shaft brake, to crappy trans up to engine breathing (in and out) and just basic tuning.

You can often get a good drop in fuel consumption just by taking it to a good Mechanic and getting a basic tune up. But offering mechanical advise on here is a bit of a lottery and often you have to make certain assumptions, rightly or wrongly, because you can't test run or sight the wagon . I made the assumption that all of the above was done and krokkie was looking for that little extra.

Big motor doesn't necessarily mean big consumption. Jeep has a bigger motor yes but also less load. A long wheel base Paj weighs in at about 2.2 tonne if memory serves me correctly, I think LOWDWN weighed his. A Wrangler is what? 1200 - 1500 Kg? My Paj is 1400 but it's a swb with a little oilburner and I've gutted it. Ask any Trucky: want better economy? Get 16 litres and 600 horsepower, but that's with 45 tonne and change fully loaded. Hook a Jeep up to the front of that and try to move it, THEN you'll see some fuel consumed!

Some of the older guys (Not me of course ) may remember the days of the Loggers crossing the Kaimais pulling 39 tons with an International Lodestar powered by a 392 inch V8 solvent burner! Of course back then they knew the oil would NEVER run out. Or the Centurion Tanks with a 24 litre flat six air cooled Conti: 6 gpm... (Gallons per mile ) That's about 60 metres per litre, of course the old Cent was 60 odd tonnes (I think... might've been more, I've forgotten... farkin alzheimers )

Point is fuel consumption in a 4x4 is relative and a minefield without even including driving style. For mine, if you're going to use your toy as your daily driver then you have to accept some of the downsides.... Like when you get glared at when a great wad of mud drops out of yer chassis and explodes all over the guy following too close .... Oh no that's an up.... well you get what I mean.

Yorick, youre right on the money, the TJ weighs 1500kg give or take a few. Heres a comparison from recent experience.

2 dr Safari, Cambridge - thommos - Cambridge = about $90.00 diesel (HELL!!!!)
4 dr Pajero 3l v6 2200kg, Hamilton - thommos - Hamilton = $70.00 petrol
Wrangler 4l 6cyl 1500kg, Hamilton - thommos - Hamilton = $40.00 petrol

All wagons did the same/similar amount of work.

[krokkie]

I am so glad I don't have a Safari!

It'll be interesting to see when I tag along next time with my Paj with it's little 2.5 turbo oilburner as a comparison. She's about the same weight as the Wrangler and is also running 33" Buckshots (35 psi on road)

But like Krokkie said, you don't get too hard core about the fuel consumption when you're doin' this stuff.

[yorick]

Heh you and me both, but that's OK Safari owners are known to have buckets of money, they need it just to buy the things in the first place.

I will leave now, I feel incoming flaming! That is of course assuming that there are any Safari Owners read this forum.

At this stage the weekend is booked solid sticking the turbo motor and new springs into Merc's G-Wagen. However that depends on whether the valve and guide arrive from Germany. It's looking like it will be a bit close. The springs however will be ready, so if we have springs and no valve ... it'll be all on.

im getting 80k to 20 bucks (11 letres) around town with ALOT of self control

ive got a plumbed and seal'd snorkel, turbo flow muffler, runs on 96 (work out cheapin in my opinion) and im running 33s andits 4 door
had a electric fan till it stopped, i heard these make a tad of differance, never got to asses it, it stoped before i got the truck timmed etc lol

but when i get all exited and put my foot down its all over i tell ya

[Raiknn]

Im getting around 8 KM/L (12 L/100KM) on the open road for mine. According to the manuals etc its supposed to be around 14 L/100KM around town. or close to 20mpg

[Mudsam]

mate my 3.5L pajero runs 5km/L with goodyear MTR on open road.

I wouldn't be so proud! 20L/100km and I'd really suggest you do something about your driving style.....

For me - 3.5, 5 speed on 33's.
Average for a South Island trip this year was 14.9 l/100km, last year was 13.9l/100km. Off road sections as high as 23l/100km such as river bed stuff and on road between 11 and 12l/100km at about 100km/h.

Well, I never go hard on road with my right foot. I changed K&N airfiler, fuel filter, spark plugs ($30 each at repco), free wheeling hub, tyre pressure 29PSI, took off the 6th and 7th back seats to reduce some weight. It still sucks hell a lot of fuel .
I am using 91 fuel. Is there any other way to save fuel consumption?

[NJV6]

If it is a 3.5 DOHC motor it must be run on 96 petrol. They have a high compression ratio.

Yours being a LWB will use more and becasue it is an LWB I'd guess its an auto as well?

I have Free wheeling hubs as well but I don't think they wuld make a huge difference as the front diff disconnects anyway. Maybe try cleaning the air flow meter and get the catalytic converter chopped out as it will be buggered by now and cloggin up the system. There is a wire that goes into the cat, just unscrew it and tie it up somewhere underneath when you get it cut out.

Good Luck, I'd hate to be only gettting 400km for a 92 litre tank......

[KiwiBacon]

Do these engines use a hot wire air flow meter? If so ditch the K&N and clean the wire. It's probably been tarred and feathered with K&N oil and dust.

[krokkie]

What do i use to clean the airflow meter with?

I guess I can't complain, I'm currenly doing around 450km on a 75l tank.

just reading this thread, my old man has a 1995 LWB Manual Pajero, 230,000kms 2.8L Diesel Turbo, about 680kms to 700kms per tank of 90L diesel, pretty good for an old girl. I got a SWB Safari non turbo 4.2L diesel, manual, and get about 500kms to 65L tank. i guess get a diesel pajero!!

If you want to save fuel, get a direct injection diesel.
My 3.9L turbo diesel rangerover gets 10km/l, my old man's 100 series cruiser gets 8-9km/l.

The penalty for indirect injection can be 20% on fuel consumption.
