Trip computer - Range function - Do you trust it ?
« on: 08 February 2008, 09:46:26 »

Just curious, my low fuel light is on, the needle doesn't move and the range computer says 45 miles left.

My old Senator used to run about 30miles after the range said 0 miles.

(Sorry if this has been done before)

Whether it can be trusted depends on whether it's got a good estimate of what's going on. It will base its' estimate on recent fuel consumption, so if that is stable and remains the same until you fill up IME you'll get the range it promises.

If you cruise at 60 MPH for hours and then rely on the range to decide that you can get over an Alpine pass (heavier fuel consumption) you will be disappointed!

I Trust it to show whats left at my current driving style, but I never get below 20 absolute minimum miles left, tend to fill up at the 1/4 to 1/8 mark.

IMO these cars are too thirsty to let it get very low, never know when you  may struggle to fill up.

Not voted as no option that really sums that up

My MV6 warns you at 30 left, take below that and at about 25 the fuel light goes from On, to intermittant flashing, if i dont fill up now I need to make sure I stop or park on a total even surface, otherwise it refuses to start again!

I wont go below 30 mile range if I can help it, main reason been that there is no 24 hour petrol station on this side of Island, so should I get called out in the early hours I would be knackered.

On my old Carlton is was prity much spot on though

For me, the fuel light coming on is a gentle reminder. Then the range display flashes at around 25-30 miles left to remind me again. I usually wait until the fuel light is flashing before I fill up. usually 15-20 miles left on the range

I never go below 50 miles left before I fill up. The orange warning light usually comes on with around 60 miles range left. Mine seems pretty accurate.

On the very rare occasion I have travelled on after it has hit 0 - but usually will take action before or when the orange light comes. At my age I can do without the extra stress of "will I make it or not...." ;)

I don't like to let my tank get too empty as I don't know what gunk is at the bottom of the tank.

When I ran mine down to 4 miles remaining I then filled the right car up. It took 68 litres which I understand leaves about 7 litres left. A gallon & half-ish means about 30/35 miles left knocking about town. Normally I'm never too far from a 24 hr petrol stn.

Has anyone actually seen this gunk in the bottom of an Omega's tank? As they're plastic you're not going to have bits of rust there like I've had in previous cars.

Just give it a good spanking every so often and it'll stay in suspension.  [smiley=evil.gif]

It's not easy to see where any muck would come from except in contaminated fuel.
