Falcon Tonner Fuel Consumption!?

[madmike]

Hey I was reading a fuel consumption thread earlier and everyone was saying they were getting, at the most, 14-15L/100 on there N/A falcons.

I'm driving a BF 1-tonner and I drive it hard sometimes like when I need to put ricers in there place, but I'm no lunatic. I'm happy when my consumption goes down to 14L/100. Right now it's up around 17-18L/100 and I've been a granny lately. Most it has been up to was 20L/100.

Highway drives I get down to about 10-11L/100.

Why is my falcon using more then everyone elses :(

I even read somewhere this guy who had a blown XR8 who was getting something like 13L/100 city driving!

Any ideas would be very much appreciated.

Hey there,

you might be in need of a service. After replacing my spark plugs, oil and air filter I noticed much better kms out of a full tank.

BA NA6 flat tray & I get 11 on highway & 14 around town. Average 12.5 for mixed use. This is without any effort to minimise fuel usage.

Anybody else have any ideas?

Ive reset my fuel consumption and have been driving reasonably conservatively and still maintain a 16.5L/100km reading.

I'm using regular unleaded fuel, not e10.

Somebody please help!

Might be a silly question, but how much weight do you have on the back?

Nothing at all. It's got a heavy duty steel tray.

Sides of the tray are off so it's just a flatbed. Got nothing on it, not even a toolbox.

Mate whats your diff ratio I went from 3.23 to 3.45 and engine revs when up 500rpm for the same speed at 100k

also check your brakes see if the calipers are sticking tyre pressure I run 35psi

In my BF 5speed 1 tonner I get around 13-14lt per 100ks around town when I don't worry about fuel. Around 12lt/100km around town if I granny it.

And about 10-11lt/100km on the highway.

I've got a steel tray, an leave the sides off aswell. I weighed it at 1700kg at a weigh bridge.

Hey update: Ive started using BP Ultimate and reset my fuel consumption computer and have been driving like a grandma constantly and the consumption is at 16.8-17.2L/100km

BP Ultimate is no help.

How long have you been running Ultimate?

I found with other car that when you start using the 98's (Vortex Gold, Optimax, Ultimate) its takes a couple of tanks before you start to see a difference.

As previously mentioned what are your tyres at?
