G'day boys. I've got a 2005 ba mkII turbo ute and the trip computer is reading a whopping 32.6L per 100km and I have no idea why. Any ideas?

Are you flogging it and also how many kms is the average over? If its just been reset lately and have been doing heaps of stop start traffic / flogging it it will read high

Well I had the battery out for about 30 minutes yesterday, would that cause it to reset? And yer I give it a squirt every now and then. Not sure about actual consumption

My car when it was tuned said on a long trip it was doing 14-15 per 100 but when I refilled and did the sums of how many kays I had done to fuel used it was actually 10.1litres per 100km.

that's the first thing you need to check. From one tank to the next. You fill it up to what you consider full and then run it all the way to what you consider to be empty and then fill it up again.

Once you've done this, divide the litres filled by the km's travelled and multiply by 100.

For example.

45 litres for 300km x 100 = 15L per 100k's.

If you've only recently disconnected the battery then the figure will be either inflated or deflated depending on how you have driven the car after the battery was disconnected. This is made worse immediately if you have done the battery and then taken the car for a hiding around the block. It'll show a history of what you have only just done. Not lifetime of the car.

Edit-The factory trip computer is a pessimist at the best of times. My history with my 3 Fords is that the actual is always better than indictated.

Very true Adam. I never even thought of that! If I've disconnected the battery for any period of time I let the car idle for a couple of minutes and then take it around the block.
