Reply With QuoteThe trick with a 3.9 auto is to keep it over 80-85 TC lockup and under 90.
That's what I try to do on good dirt but the soft tyres reduce the economy.

I was doing a search for something else and found this:
"The drive to Iringa was uneventful if somewhat stressful. Tanzania’s traffic police are notorious for their radar speed guns and with the national road limit being 80km/h and the town limit being 50km/h and the fact that you pass through numerous small villages and that there are seldom any signs indicating a change in the limit plus the fact that everyone else is doing 120km/h ALL the time, makes driving a little tiring. I soon settled into doing 95 odd km/h on the open road and slowing to 50 in most of the bigger towns. Well the result of this driving was that the old girl (the Rangie of course) was using virtually no fuel. We were going along so well that we decided to pass the farmhouse and head on for another campsite the other side of Iringa. I filled up in Iringa and was stunned to see that our fuel consumption for that stretch of road had been 13.8 l/100km.Considering that were have been averaging 18l/100km this was incredible for a fully loaded Rangie traveling in fairly hilly country. Surely a record for a Rover V8? I know some friends with Toyota 2700i bakkies who would love that kind of consumption…. I must say the old girl was running very sweetly and I was singing her praises to Cindy as we left Iringa. Yes, yes I can hear all you Landie owners saying don’t tempt fate but she really was running very well…."
I have heard that keeping your speed to about 90kmh does the trick, though I haven't tried it yet. The website is here: philv's Home Page. in case you want to read the rest of the story, which is quite interesting. (And just goes to show how you should do your own car repairs, or at least check what has been done!)

Yes, that's it, the right speed and with, in your case, the transmission not slipping. This guy's car is a manual, though I don't think he mentions what kind. I don't think a Torqueflite would be too good, though!

My RRC users 25-28 ltrs/per 100km of LPG. Its a 6.3ltr supercharged V8. I rarely drop under 100km's up hills etc etc. Towing a trailer fuel economy doesn't really change.
The timing I run for lpg is 18 BTDC at idle and 28 degrees total timing (this has help to make the engine alot more responsive of the line).
I have a t700 which i can lock the convertor in any gear. I found this does help with fuel economy (approx 1/2 km better per litre).
Cold air intake, strong spark (msd system) and timing set right really helps for lpg.
My l322 4.4 V8 long term average is 14.2 ltrs per 100km.

well SWMBO finally had to put some diesel in my disco... last time I put dieso in was something like 2100Km ago....
not bad for a standard size tank.

SupporterI've consistantly got 13-13.5lt/100km on petrol, and 18 on lpg on the hwy. That's at a very easy 95-100km up the Newell whilst very heavily loaded. If I drop down to 90 I get about 12.5!
I've found a bit difference on the hills is if you push it to maintain a speed. By putting the accelarator down say an inch and keeping it there it saves a heap. And when the roof rack is on, you can kiss economy goodbye.
I've often wondered about these hydrogen bubbler systems, the theory is there, but i'm simply not brave enough.

I could easily live with that !...Originally Posted by benji
Hydrogen bubbler, well, how many amps do they use..and what hp is used to generate those amps ?

I get 19-22L/100 around town (I don't baby it either - found I get around the same if i baby it or not).
4.2L flapper 5 speed, 2" lift, bars both ends, long range tank.
my best ever was 13.5l/100 on a west QLD trip between Winton & mount Isa, very flat, no stops etc. interestingly the 3L patrol I was with was getting around high 9L. (weight does make a difference).
On the open road I can push for 850-950km out of the tank (130L)
having said that I bough a v8 range rover, I'm not interested in fuel efficiency. just the lovely noise and the car not tractor like performance

gday all, i had a 78 2door 3.5 v8 in the early nineties. i used to get 600klm to a tank driven carefully,it had a four speed box and standard tank.[82ltrs],. i ended up buying a snorkel from john e davies in sydney. after fitting there was a big difference in performance , and fuel economy was slightly better also. i travelled around australia for 3 years in that classic. it never let me downtime trying to find another snorkel the same that i had and put it on my lse, it certainly helps them breath better.
