Rubbish OBC

[D]

So I get into the car with OBC claiming I have 50 odd miles till empty. Drive rather spiritedly (as much as you can in an Elite) and reach destination (about 16 miles away). Spend a few hours shopping and get back in, drive off and as I canter down the narrow spiral path from the car park my engine cuts out. Takes me a while to realise it was actually dead till I realise that the steering has no power assitance. At this point I am sweating a bit as getting stuck in the narrow track means obstructing the hundreds of Sunday shoppers trying to get home. Thankfully I reacted in time to nudge the gearbox into neutral and coast all the way to the bottom and mount the kerb so as to not obstruct other drivers. At this point I am wondering whats going on as OBC still reads 10 miles to empty, needle in red but not at the very bottom. So I am about to call recovery when I try restarting and the engine fires to life. Excellent, drive off to the nearest petrol station and on route the engine tries to die on me again (twice). Somehow make it to the pump and fill her up (£90  ). Restart and no problems ever since. I can only presume the OBC was wrong and I had very little fuel in the tank.

I used to always fill up at the quarter mark, but have been lazy since I changed to the Omega. Lesson learnt. And hopefully no damage done to car. And never believe what the OBC tells you.

The range assumes that your fuel consumption remains constant over the remainder of the tank. Put your clog down and, as you have found, it can look a bit optimistic. The orange light is more trustworthy.

Also sounds like you were suffering fuel "slosh"

[Vamps]

swmbo has a terrible habit of 'pushing her luck' why o why drive with so little fuel in the car, even if driving to a filling station, it only takes a jam or a diversion and you are up the creek.......

I presume you're talking about the shite that's been allowed to slosh round the engine due to the fuel going so low. If not, I aint got a fckuing clue what you're talking about

Ime they dont tend to start up and drive to the nearest petrol station after they run out (although "slosh" could expllain why it did - maybe) but I would be doing a paperclip test just in case.

Agreed. On the occasions my Omegas have been "out of juice" - they aren't going anywhere fast until you get a petrol can...

Perhaps the incline of the road? Or maybe slosh. No codes at all.

Imagine the fuel tank is the large bowl, and the fuel is the puke.. as you drive around the fuel will move around the tank - since the 'pickup' of the pump is only in one place, all it takes is a hard corner et viola, you're sucking air (or, in the analogy, have puke down your shirt)..

Still pretty accurate if you ran out at 10 miles to go.
