I need to know -

How big is a standard tank in an LC/J.

and

What would the average fuel consumption of an LJ 2850 be?

Cheers, Tim.

So you get about 200km out of 40L?

Hi

That's only about 14 mpg (20lts/100km). Should get at least 26 - 28 mpg properly tuned and driven.

Why worry about how much fuel you use ?..
The car is over 30 years old and they don't make the same kind of fuel back then as they do now ..super is long gone... And at over $1 dollars a litre you drive these cars for fun not as a regular driver..

well i can drive to newcastle from my house on the central coast (like 45 minutes at speeds rangine from 60-140, mostly cruise on the pacific highway at like 120, but i drive there and back, adn it uses about 1/2 a tank of fuel, and i have a heavy right foot. that is on a mildly worked 202, with tripple carbies.

dunno how you can only get 200km from a tank!!

I believe Lows2 has a 350 Holley.

I have one too. My economy is worse cause I think its leaking a bit.

Will change to Triple SU's just for kicks.

Sorry Rim, I don't count how many kms I do on a tank. But at a guess...around 150kms/40L ... I usually fill up before that just so I don't run out.

Tim,

I just came back from a run from Sydney to Tamworth in my GTR - distance 400 klms each way. I have a worked 202 in my LJ with 3.08 diff. Fuel consumption was 10 litres per 100 klms. Although is was nearly all highway driving, I was very happy with the economy. So I know I can get 400klms out of a tank on the highway, would get about 300 klms around town.

Mick.

I'll go with that then, Mick, considering our cars are almost exactly the same, except mine would probably be a bit better than that with the stock 173 and 3.36 diff...

Cheers guys.

Tim I averaged between 11 - 15 litres per 100 with the LJ on PULP (173, M20, 3.36 Banjo) And got about 350 - 380 ks out of 45 litres.

On gas I average similar figures, say 12 - 16 litres per 100 with the LJ (now 173, Celica 5 speed, 3.36) my best so far has been 600ks on 66 litres of gas.

just a bit of interesting information I thought everyone would like to know. I saw this on an SBS documentary.
when the Model T ford came out in 1925 the average fuel consumption was 25mpg.
now in 2007, current trends in America are indicating that the average fuel consumption for a family car is 14mpg (with the introduction of the hummer).
so in 82 years you'd think we'd develop more fuel efficient cars (which we have to an extent) and that people would actually lean toward them... but no.

They have........except its affordable to drive something bigger that uses more fuel.

Fuel is always a hot topic, here in Aus we have big V8's drive and love em, were tending to stop buying modern ones for every day cars, but buying old girls for weekends are on an increase soley down to fact that we cant play mon - fri I rekon,

If I could find an original small block HK,T,G sedan or wagon, I would drive it daily just for the fact I miss driving a V8, until then ......

I will drive my 998cc Mini to and from work putting in my $20 for over a weeks running, how many K's dont know dont care,and thats with a heavy right foot pushing it along :spoton:

Rim what a Maths prject school is fun sometimes, I miss it------------for the girls in skirts

here's something interesting

i owned a vx 5.7L 6spd with a 3.46:1 lsd, fitted ss ind cold air and it the dealer fitted hsv exhaust on the rear half.

Around town giving it a quirt every now & then would return 450-500 but on a trip say from the central coast to perisher it get there on a tank and drive around up & down the mountain for 3 days - easy 8.5 - 9L/ 100.

one time my trip said 475 distance travelled with 610 to empty, i took a pic as i couldnt believe it!

These late model 8's can run on a snif thats why i wouldn't stuff around with a v6 etc when you have the best of both world in efi 5.7 - 6.0/L.

Please don't think I am denying what you say but the fuel guages (which also run the trip computer) in VT onwards aren't reliable. I am forever supplying fuel to Commodore owners with 1/4 of a tank showing and 75klms left on the trip computer.

My engine is completely standard BUT has not been running right for ages & im pretty sure its been leaking fuel from carby, it doesnt really worry me how much petrol it uses, it does the job for me on a daily basis & i drive it pretty hard. Should see an improvement once i get my 202 built.
