Fuel Consumption (merged topic)

[crisso]

I recall seeing a thread which took the pi$$ out of a Monaro's fuel consumption and showed a photo of its 'Range to Empty' reading on the dash

haha yeah, that was my mate's monaro after the Bathurst cruise

Even with the standard injectors, ive found that it doesnt read exactly but pretty close. The best way is fill her up and divide the amount of kms you done by the amount of fuel you put it and theres your answer, let you know how close the tripmeter actually is. But it sounds like your pretty happy with the fuel consumption so that's really what counts.

Yup Shane & Luke agree to most of your points.

Firstly I always use actual rather than 'calculated' and thus the figures quoted are just that - actual and you're right on the other count too......I'm happy.

To be precise, with the injectors I am using the fuel consumption figures on the dash have to be increased by a factor of 1.31 ie my indicated fuel consumption was 8.3l/100km but actual was in fact 10.8l/100km which was confirmed by the fuel actually used over the period.

Unfortunately even that figure can give rise to errors over shorter trips as it's nigh on impossible to 'fill her up' as the last few litres are like stuffing marshmellows into a soda straw. Nevertheless, for the non-believers do the caluclations yourself, 530 actual kms on less than 3/4 tank gets mighty close to 800km.

To that add a smooth idle, constant power increase with throttle and speed, no surge, shed loads of torque, no need for replacement valve springs, boost sustained below 9psi......testament to a sound mod, bloody good tuner and the careful use of a dyno; now If only I could get that bloody power steering shudder sorted.

I can get adel to melb on 1 tank 700+km

I have no doubt that our T's can get very reasonable fuel economy, considering how heavy they are. My last highway trip nearly 1200km I averaged 10.5k a litre which I was very happy with. If I had had 270RWKW and got the same as you Dingah id be happy as a pig in sh*t!

...onya Shifty...

Shane - exactly my point and the same point macka has been making on other threads in the past, get it right and you can have both - perfromance and economy...however it is the fact that 270RWKW turns hydrocarbons into happiness by the shed load that leads to the poorer consumption figures - it's very hard to resist the feel of the never ending shove in the back - bit like a high performance aircraft at a fraction of the cost and risk.

My fuel consumption is like 16.9/100 and I drive a standard BA XR6.

I do like to accelerate here and there but I wouldn't say I thrash it.

Should I perhaps get that checked out?

[FPV 521]

but my understanding is that once injectors are changed, all your trip/ fuel figures are no longer accurate

That is true

Good point, must remember that when I get mine done

I drove from darwin to melbourne recently in my stock T. Leaving the territory (no speed limits + no traffic = stupidly fast) I was only getting 350 from a tank. Slowed down once I hit civilisation and I was getting about 650 from a tank. that's cruise at about 140 the whole run. And on another topic, I did the drive with a mate in his VX Commondore. I had to stop in every town and wait 30min for him to catch up. I just got back to work and hes sold it and bought a T ute.

This week on a tankful of the new Vortex 98 I achieved the excellent economy of

20lt/ 100ks measured on actual fuel in v ks covered This was with a fair bit of stop start , but the thirst seemed significantly more on this juice. I will give it another go and see if it improves as I get a reasonable discount if I use it , just got to weight it up
