Well don't be too surprised if the 6mge doesnt get you too much further.
For starters, you will have to run the thing on a 5mge ecu becasue the 6mge ones are uber difficult to find. As a result my one always ran rich up high esp.
Secondly, you will be more likely to give it more poke due to having more power and consequently use exponentially more fuel.
I never really measured my consumption but i would say it wouldnt be too much better than the 5me.
I shall get back to you about the 'new' fuel comsumption after a few tanks.

In my experience, the 6M was slightly better on fuel... still not great though. From memory I got around 300km or a bit more around town (depending on how much of a hoon I was at the time), and ~400km on a highway trip. That was with the 5M-E ECU though, so with a proper 6M-GE ECU it would probably be better again.

what about 7m's fuel consumption...
basically i am fed up with teh 5me burning a hole in my petrol money pocket, and i am open to suggestions for a better (much) fuel economy solution, engine swaps etc.

how big is the tank you are talking about?
My 1g-gte soarer has a 60L tank and i get 500ish k's around town and about 600k's on the highway. I thought that is pretty good as it is only slightly more expensive than my parents sv21 4 cylinder camry.

when i firt got my supra(7mgte). i had to drive a friend out to geelong from melbourne, ended up driving a total of 500k's and i remember filling up the petrol tank twice but i only put in $20 each time so $40 got me 500k's. i had the button for eco on too.

i can get up to 650km on a full tank highway cycle (70L)
but down to 350-400 when pushing it city cycle
and thats with a 4.1 + w57, the worst combination

yes, yes it was
but it was sooo bad (3500 freeway, almost 4000 country) that i didnt actually want to know how bad it was
i just kept putting fuel in when the light came on (every couple of days)

That's pretty bad. I get about 450 or so k's around the city on my 7mgte. On the highway it's even better (about 600). I was actually pleasently surprised.

M series engines aren't very good when it comes to fuel economy. The later 7M's are better but still not great. If you want to do an engine swap for better fuel efficiency, you'll have to think about something completely different - a 2JZ for example! My 2JZ-GTE uses much less fuel than the 6M used to, and I imagine an atmo 2JZ-GE would be better again. Not a cheap way to do it, but if you want to save money you should be driving a Corolla or something.

My old 7M used to be pretty fuel efficient, would get 450k's around town and I think I got 650k's long distance (once).
When I got my new supra with 7MGTE the fuel economy was crap, but it was running very rich (under 10.0 on the dyno).
As a note my 1u gets me 450k's around town and something stupid long distance over 700k's. But that is with a properly tuned computer and one that knows when your not on load and adjusts the fuel down to 14.7

dont even start on fuel consumption try a 4m with a 350 holley it
SUCKS the petrol back.
But my fuel gauge is fkd and i dont like running out of fuel so i top it up every 4th day, but its like $50 a week just to get to work and back,$80 if i go cruzin

A 3K in good condition will use bugger-all fuel, provided you don't flog it everywhere. The problem is you probably will flog it everywhere because they're so damn gutless!

What's the 1G-TT reasonable fuel consumption ?? How far would 1 Litre get you ? or how many litres for 1 KM ???
I know this sounds corny but if someone knows the math i'd like to verify this with my 1G. Don't know if i'm at optimum fuel useage or burning holes in my pocket.

Back in the early days, i mean the 60,s the toyota m series motors had better fuel economy than any of the4m late,5m,6m, 7m,1/2jz engines of today and you know how they did it
"COMPRESSION" The old 2m had more compression than even a vvti
2jz of today , But as the years went on from the sixtys and the quality of fuel slowly deteriorated so did the compression ratios of all the motors , look at the 4mu 5m,s in the crowns, you needed to own a bank to keep them running. But then as electronic technology proceded with spark contol, closed loop etc the engines compression ratios started to rise again allowing them to be more fuel efficiant despite the crap 91 octane fuel they have to opperate on.
Give some of the later m series engines compession and you will be amazed at the results.
I had a mx 83 cressida and i managed to acheve 9 lt per hundred
hwy and thats auto and not the lightest car around.

According to the information I have, the early 2M engines had a compression ratio between 8.5:1 and 9.0:1. By comparison, late-model 7M's were 9.8:1 and current VVTi 2JZ's are 10.5:1.
I seriously doubt an old 2M would even come close to the fuel efficiency of a current model 2JZ, but you wouldn't really expect it to would you? Engine technology has come a long way in the last 35 years!

very very rare to find a 9.8:1 7mge
not sure if they were a european model spec, but they pretty much dont exist here. everything we got (up to 91-92) was 9.2:1
euro spec also got different cams for a bit if i recall correctly

dispatcher,
if your car is stock, figure on 7/8l per 100km on the highway cycle, about 10l per 100km on average around normal traffic and about 13l per 100km when you're giving it stick.

there are a few different model 2m,s tho and many different head combinations, the 2m round has a compression ratio of
nearly 11 to 1 , ever seen a compression gauge on a m series engine hit 230 psi , you cant do a hot compression test on a 2m because you'll wreck the compression gauge , they actually will fire from compression ignition.
A good 2m in a ms45 crown will achieve 8.5 litres per hundred

Pretty much what Cambelt said.
My old 2M used to run 220 psi dynamic compression COLD. It ran 8853 high top pistons and a 41012 round chamber head. It had a measured compression ratio of around 10.5:1. When I initially ran it in my MS45 with a single Aisan 2 barrel carby, 3 speed overdrive and 3.9:1 diff, I could achieve around 10l/100km on the highway. Of course, the triple SUs wrecked this around town, but with a steady foot I could still get near this on the highway.
The 4MU and 5ME motors all have low compression (8 - 8.5:1), are burdened with emissions controls, run unsophisticated analogue EFI management (not even an O2 sensor here in Australia) and lug around heavy shells.
I think it would be stretching the truth to say the old M are are better than the new JZ series motors in the fuel efficieny stakes, but a good condition well tuned 2M would certainly have given it a scare.

If your fuel gauge is anything like mine, it's FAR from accurate. I look forward to seeing the averaged results after a few tankfuls. It was always going to be good on fuel though; my 2JZ-GTE uses way less fuel than it has any right to, and the GE can only be better!

STR8 2.8,
With my solution to not burning much fuel. It is as simple as walk to places which are in walking distance .
Also stop draging cars unnessary around town and thrasing the car and you will achieve your high fuel economy .
Seriously, have you had the Injectors cleaned out? Petrol Filter Changed and the car tuned properly?

Toyota fuel gauges have never been fantastic 
I get 11.5ltr per 100km on the hi-way cruise set to 108 ding donging along (MA70 owners with a digital dash will know what im talking about)
not bad for a battleship supra with a 7m-gte and auto.
its reving at 2200rpm@100kph i think it could do with a taller diff for abosoloute tightass miles but thats something ill look at when i stick a torsen center in.
Hopefully higher compression will help both power and economy considering i run it on synergy 8000 and nothing less anyway.
