I dunno what's going on with my car (stock EB V8, auto) but it's been getting better & better with fuel economy.

After the GOR cruise, I filled up at 520km, with 100km left in the tank (10c/litre price difference b/w pakenham & gippsland). I was expecting to get maybe 350km to *that* tank...

On the highway I find that I'm now getting low to mid 9's per 100km.

For normal driving (85% highway/country, 15% urban/"fun"), I'm geting low 11's per 100km.

I'm using whatever the cheapest 91RON fuel is that's available, and I haven't changed my driving style, yet it's running sweeter with every fresh tank :wtf:

Oh, and it's due for a service :angel:

I've found there is a BIG difference between h/w and city cycles on a modified EFI windsor. I'll get around 11 on highway cycle but driving as lightly as I can around the hills where I live I'm currently on around 20L/100ks

Cruising around i'd say 14L/100km about right. Foot down, not exactly sure but its a LOT. Maybe 2-3L per km? or 200-300L/100km. A lot....

:AAHHH: 200-300L/100km! You must get little more than 32.5km from a tank! Boy those blowers are thirsty :wnc:

Thanks for all the feedback so far guys..

Basically with my car...i only drive it on the weekends...so say i put in $40 of petrol...(fuel gauge orignally on 1/4)...it goes up to over 3/4 full (as indicated by gauge)...i find with 2 full days of driving its back to just over 1/4 again...i cant tell my exact km usuage as the odometer/trip meter is currently out of order...ive tried babying it around as well it seems not to make a difference..

I think i may have a dud sensor somewhere perhaps?

Yes with foot down/boost up i get a fair bit of pressure building up in the fuel rail thanks to the FMU.

But when crusing ive found its actually an improvement over standard consumption. Just gotta resist temptation.....
