vy ss fuel consumption

[Conn]

hey guys,

just recently bought a 2004 II vy ss ute auto, it has 61,000 km's on it and just had a 60,000 km service, it is completely stock bar a dual 2 1/2 inch catback exhaust, the computer says it consumes roughly 18 - 21 per 100 kms all depending on traffic condition, i do not thrash it either. a workmate of mine has a vz ss ute auto and goes through about 13.5 litres per 100? any suggestions. thanks.

What kind of traffic are you driving in?

 

[Conn]

stop start traffic, i'm in melbourne driving home from work in peak hour through royal parade (zoo), that kind of traffic everyday..

Hi mate , there is a few things to consider before thinking its a mechanical issue. What is your average speed on the trip computer? As said, what kind of traffic are you driving in, and also being new have you been giving it a bit here and there? Reset the trip computer and drive it like a girl for a few days and see how you go

 

[Conn]

sorry danja, just saw you're in sydney, it's a one lane road and takes forever to get through it, takes me over an hour where as it realistically should take roughly 10 - 15 minutes

i have tried those things, i fill up and reset it straight away and don't give it to it at all, i think my ave. speed is around 30ish? the best i think i have gotten out of a full tank is a smidge over 350 kms?

18l/100 is probably right with ave speed of 30. If it was up around 45-50kmh your consumption would be obviously much better. Does your mate drive the same route as you?

 

[danja]

Yeah, if I take the busiest route into Sydney in peak hour I'll often see it around 18L. It's not abnormal.

I found a route which I pay a toll for, but I now average 13.5L (avg speed ~40) and save heaps of time, so I don't mind spending $3.50 a day

To answer your question though, 18 might be about right, even with granny driving you'll be doing well to get 15-16 in that kind of traffic.

 

[Conn]

oh ok, i guess that's fair enough then, another thing...
what should i be getting on the highway? the best that i've gotten it down to is 12 litres per 100 and that is sitting on 100 for a very long time? i heard it should be around 10?

 

[vy-346]

yep sitting on 100km/h for a while 9-10l/100 is easily achievable in an Ls1. Again just reset the trip comp before you hit the highway which ur prob aleady doin.
