Fuel economy

[trouble]

just wait untill ya lift it and put some bigger tyres on, my fuel econonmy is now sitting on 12l / 100kms

12?!?!?!?!?!
Well I just got back from a 5k trip 40/60 dirt/bitumen with all tyres on 25psi (including CT) and managed an average of 13.4. 2" lift all round bar work and larger tyres, sitting on or around 90-100kph. Im happy with that!!!

So, our new MN 2.5 L 5 speed auto dual cab went out for its first trip this weekend to Nelson Bay and back travelling 462 km and using 44.8l.

That's 9.69 l/100km which somehow does not correlate too well with the advertised combined fuel ecconomy of 9.6l/100km for the 5 speed auto.

Load wise was 4 people and minor luggage sitting on 110km using cruise control.

Is this consumption normal? I know its pulling almost 2 tons + passengers etc so I was simply wondering if this is typical
as I expected highway driving to be a little better than 9.69l/100km in order to get close to Mitsubishi's adverstised 9.6l/100 combined cycle.

cheers

That is great economy for the Auto, Best I have got is 12L/100km, and have had two tanks as high as 15L/100km

I have just under 4000km on my new MN Auto GLX-R. I have been getting better economy through every tank with the worst (first tank) being 9.8L/100km & the last tank being 8.2L/100km

I am yet to take it on a long trip to find out how good it goes on the highway. Im stoked with it so far.

Wow!

Thats better than 700km per full tank, your doing well MN25DT.

During city driving, after filling up to the max, my low fuel warning lamp comes on at about 520km, and after refilling
usually with about 62L that equates to around 11.9L/100km, so your 8.2L/100km is quite impressive.

I must say even if I drive mine slower than drunk turtle I cannot get even close to your figures.
Proof is as I already mentioned during my trip last week to Nelson Bay which was 95% highway driving and only got about 9.6L/100km.

Even taking driving style into consideration, this doesn't explain what can be causing these very large discrepancies on identical cars............. I can accept say +/- 50km per tank but here we are talking about +200km per tank.

Perhaps engine build tolerances are the cause?

cheers

I am getting consistant 11.5 (Mainly city 80% 20% freeway) last 6 months.

When new first few tanks were 10's. Then crept to 10.5 then 11... You get the story. Mine is 12months old (28,000km).
Highway (cruising no load 110 cruise) I can get 9's easy even broke into 8's for a tank. Nowadays 10's is it...

I am now starting to head towards 12

Just had 30Km service so will see if helps over coming weeks/months..

All in all it is very economical given the size. No worries about the yearly fuel bill for this vehicle. I have had some cars that would suck 12L at idle... mind you petrol was 1/3 the price too...

[pepelepew]

These things do seem to loosen up a bit over time. Always calculate usage at the pump, that bloody display reads on mine around 1.5l/100 LESS than it's actually using (before i chipped/blanked). But the MN still surprises me every fill, though I wish I could get me a reasonably priced long range tank that'll work with the factory locker. Filling once a month would be a buzz

Just clocked over 620kms on my current tank this morning & i still have a 1/4 tank to go....i just assumed they would all run at about the some consumption levels (give or take a bit) but i couldn't believe the differences i have been reading in this thread....

[borngeek]

MN25DT : I agree with helicopter those are impressive figures for city driving (poor Daryn he will be crying)..

Update your shed and put up some pix when you get the chance a location would be cool too

[MN25DT]

Update: 723km from 62lt = 8.6L/100km

Seems as though my efficiency increases since buying the car are starting to plateau - I'm still stoked with that for everyday driving. Should be doing a run down to Batemans Bay in mid August so I will update how i go.

Here's mine:

ML 3.2l auto, 265/75/16 Mickies MTZ (speedo has been re-calibrated), 98% city driving - 12.5l/100km.

[RHKTriton]

We all get sucked into the the economy debated but when you think about it - a possible extra 2 on 3 $ after driving 100k - not the end of the earth.

The killer costs are rego, insurance, maintenance and parking! Maintenance especially if you "dance" along with the dealer's tune.

I've had from 9.3 to high 11s over highway and local running around. Lately seems to be using more and I've been thinking that the winter formula they use for diesel may provide less energy. Will wait and see what the warmer weather brinigs.

never a truer statement! + $MODS + $TOLLS + $FINES + = ....

edit:

just speaking with brother who's a truck driver...
the bosses are complaining that the new reduced sulfur (some now no sulfur) in diesel is reducing truck performance and increasing costs.... told me about some new regulations about emmissions and how the whole industry (from a bizo perspective) is looking at recouping the costs./.. look for increased transport costs soon! but more economical vehicles with less emmissions... (they may not be worried about performance so much)

Hay all, I have a ML09 V6 Petrol Manual GLXR pretty stock apart from the Canopy and rack until recently I have been averaging 13lt/100klm which I thought was ok but I have just put a set of Cooper ST’s (245/70/17) and have noticed a big jump in the juice used, it is up around the 15.5 mark on the first few tanks !

Does this sound right?

[Kegsy]

My GLX, MN 2.5hp has returned 8.3 & 8.2L/100 on the last two tanks, and the tank before I wasn't sure as it was dealership filled to just under 1/2 tank.

Happy as larry with the economy ATM, and thats been driving 1/2 heavy traffic and 1/2 highway.

Can't wait to see how it goes when the ARB bars go on and some decent tyres.

When I changed from the standard 245/70/16 HTs to 265/75/16 MTs, I noticed an increase of about 2l/100k. Probably a combination of speedo being more accurate, change in gearing and more rubber on the road.

Getting an ARB deluxe bar next week so will be interesting to see if that makes any difference.

[Diddy]

Im getting an avg of between 8.8 & jumps to 9ltrs per 100 klms when towing the 3 quads and all the bike gear and the family.and i run the following mods daily heavy duty ironman susp,265/70/17 muddies steel bar and winch and a big toolbox with my work gear in it. I guess every car runs different

[Try-it-on]

I got 585kms from 60.8 Litres on my first tank when the fuel light came on. That's 104L/100kms if my maths is correct, and I'm pretty happy with that because I did give it the odd boot full from the lights to see how she drove, and that was 100% city driving.

This tank - it's second tank and with now about 900kms on the clock - is looking as if it will be better, but probably not massively better, but should get below the 10.0 by the look of it.

That's an MN Manual with Highline canopy that sits quite a bit above the roofline which can't be good for economy. It was really encouraging to have the fuel light come on with still 1/8th of a tank or so left, because the Patrol got right down to the final line on the gauge right at the E" mark, and still never had a light come on, so I have no idea if it even had a working light.

If this engine loosens up and starts giving even better economy, then I will be seriously happy.

[biggibbo]

My MN Manual on its first 3 tanks is averaging 8.8 litres per 100 KM ( did give it a bootfull over the weekend) but more than happy with those figures, but the trip computer is spitting out slightly better consumption figures.

[Greedy]

That's 104L/100kms if my maths is correct,

I'd suggest your maths is a little out. That gives a range of about 75km give or take on a full tank. May have missed a decimal point in there somewhere.

[4x4fun]

Keep me posted i'm interested in the same bar, once i get all the ARB bar work, winch and ultimate lift i think i'll be getting the same as Try-it-on 104lt/100k

Damn, that's a big difference.
I know I'm not the lightest foot in the world, but Canberra is half country town and half city, so my 10.4 seems disproportionately bad compared to your 8.8
My foot, and the canopy's lack of aerodynamics, doesn't really explain that kind of difference.
But that seems par for the course here, everyone is quoting some pretty major differences in fuel use.
You'd wonder if Mitsubishi get the engines and cars made in the same place with such huge variance from one vehicle to another.

[biggibbo]

My car is pretty much stock with a soft tonneau. I've got the chip but won't put it back in till I hit 5000 km. Most of my driving is Highway (Newcastle to Pennant Hills daily). I'm finding if i stick to 105 km or less I can get about 820km out of a tank, but if I do the 110 km speed limit I only get about 700 km (big difference). Looks like the sweet spot for mine at cruise is 105 km (just off boost I'm thinking??) The amount of fuel and $ I save is making me drive like a granny.

Wondering if the Chip-It guys can give me a tune that will reduce power (sounds crazy I know) and fuel consumption for my daily commute and dial it back up for the weekends??

Either way the fuel economy is kicking arse over my ST-X Navara, that thing was lucky to get 600 km out of a tank no matter how I drove the thing. Very happy with the swap over.

[Diddy]

just put tank of bp diesel in and 750mls of 2stroke oil and a new air & fuel filter and did a 100klm drive from bp beresfield to medowie to newcastle to warners bay & back to beresfield and refilled back at bp at berefield and the car took only 8ltrs to refill and i choca blocked it comp says car is running at 7.8LPH my calculations worked out at 8LPH or 12.5klms per ltr

[4x4fun]

Hey DID, i just showed the wife ur photo and she got all annoyed and said "well take a good look cause we'll never see that on our car"

[bobtriton]

well 4x4fun, there are things we should never show our wifes, there is nothing like showing what we have done, after it´s done, but not the things we wish...

I finaly got a better mileage, in my third full thank after blocking the egr valve, I finaly got 10l/100kms. with a help from "Lucas diesel treatment" that I pour in my last thank.
