Thread: mpg of 2.25 petrol

I've never owned a 2.25, but had three six cylinder 2As, the last one on gas. When I calculated the mpg I was shocked to find it 9 mpg! I thought wagons are heavier and gas will use a bit more but it got me depressed about it until I tested the speedo and found the speed right but the odometer was out and I was actually getting 14.5 mpg. It meant the gas 2A was cheaper than the TDi I have now.
Hills will knock it around and the big body will drag a lot even when there seems to be no head winds. Keeping below 80kmh seems to give fantastic mileage in all of the LRs I have had but I am too impatient to do it for long.

G'day All, Gee Paul the Bloodbox has a co-efficeint of drag like a brick, I'm assuming that's what you went in, mine does around the same but has never done a 700 mile round trip either, come to think of it, drove it for 15 miles last year (yeah 15 miles in total for the year LOL) Chloe averages around the 20 mpg so does Dinty but they are a lot smaller than a bloodbox anyway mate cheers Dennis

kept at a steady 80kph my record economy out of a shorty 2.25 was 21mpg but realisticaly i used to average 15-17mpg but then my rovers were typicaly loaded with about 300kg+driver by the time you got the recovery gear, tool box and second spare onboard.

fuel consupmtion goes up expenentially with speed once you get much past 80kph with the standard sIII running gear.

How about with an overdrive ?
You should be able to go over 80 for the same economy ?

I wouldnt want to bet on it, the areodymanical preformance of a landrover becomes more "house" thand "shed" when you go much over 80.

The overdrive saves engine revs yes but you dont get something for nothing....

coupled with extractors to increase airflow through the engine and reduce the chocking of the well flowed landrover exhaust manifold you might squeeze a little more out of it but I dont think youd sustain 21mpg if you wanted to do more than 80, they just aint built for it..

Big red has a noticable change in fuel consumumption at the 80kph mark on highway cycle, I found this out towing the slings trailer for an 80t crane while I was in townsville the crane was flat out at 85 so i followed at that speed (and slower) and managed a never repeated (by me) 7.5l/100km but it was also at night, air con off, technically tailgating the crane but I had about a tons worth of trailer on.

on the trip back I didnt have the trailer and didnt need to follow the crane. I sat on 95-100ish due to road conditions and only got 9.5ishl/100km the distance covered was depo-depo on exactly the same route (company paid for fuel).

Normally on flat road I will use the overdrive and travel around the(45-55mph) 80 - 90km mark.I generally dis engage at 40mph(80ish) when going up slight slope or hill.Seems not bad economy wise doing this,seems the secret in the bloodbox is momentum.However really notice a huge consumption increase on big hills and even below 80 in normal mode revving high. All in all I surpose this averages out better then I give it credit.We went out to Bunya Nat Park, so alot of climbs which would have skewed the figures.

Dennis what are you doin man...15miles...you sooner sit in and knit the poodles a jumper or something .we'll sort that when I get there...bloodbox drags in downtown Cessnock..

well glade to here it is not something wrong with those figures.

here's where we went:
4 days straddie
then 5 days
Kenilworth thru Imbil to Gympie. From Gympie thru Kingaroy to Bunya Mtns.
From Bunya thru Kilcoy to Bribie then from Bribie to Mt Mee....

Didn't want to go to far from home as I was not sure of the bloodbox's abilites and pitfalls. So a good shake down trip. Must say that I now have no fears about doing the block in OLR....one hellva truck.

cheers

You'll have to come out with the Numpty's along the Powerline to test the articulation. There are some good tracks without being silly, and plenty wide enough for the Bloodbox.

G'day OLR-067

First Up, HAPPY EASTER

That's not bad figures if it is taken over the total of that trip and those areas, particually with a Bloodbox I drive mine a little bit faster and I get about 15-18 mpg depending on wind conditions, 12 mpg over long distances in a stiff headwind, (100 miles into a Southerly coming home from Bundaberg one trip) but I haven't got the benefit of the O'drive, but would equal it out as mine is a GS.

If you are getting those milages in the Bloodbox the motor and transmission are in good nick and it is in tune


cheers
