My AU falcon has a strange issue lately with the fuel/gas guage. This car is 100% dedicated gas.

I filled the whole tank up the other day with 65L of LPG gas. The guage went to nearly full... 90% full (DTE was 306KMs) and I've done 150KMs and it now shows empty with DTE at 14KMs.

I will use another example to be clearer. I went on a drive from Bankstown (where I live) to Fairfield (destination)... distance is about 18kms. The guage was on the half mark... then i got to my destination, it was at 1/4 left. When I drove back home (18Km drive back), it went from 1/4 to empty with the fuel light on!

I cannot believe a falcon would use this much gas in 17KMs! is there something wrong with my guage? or is this car just chewing up gas?

I recently had the tank inspected for leaks to pass rego (cost me $250)... they also repaired the guage cause it's been dead for more than a year now.... so my guage works now but I am alarmed at the rate it goes down. Does this car really chew 65L of gas in 150KMs?

So... faulty gas meter or just plain crazy gas consumption? or did I fill up with some dodgy gas that evaporates quicker than usual?

If it's a faulty guage, I'm going back to relying on the "fill up at every 200kms" method.

Thanks.

easy to tell if it is a faulty guage

fill it up again

if 60odd ltrs go in it is working right
and u have a gas leak AFTER the tank

if not the guage is f**k

So how many liters were you useing to go 200km before?

My AU goes about 320km on 50L

The gauges and senders are well known for not being the aucurate things in the world.

I didn't really take notice... about $35 of gas for 200kms?

I filled it up the other day with around 60L and I did 306KMs.
