Hmmm, personally I think the computer trip meter is a little dodgy?? My fuel gas light is already on, and yet it mention it still have 110Km to go before empty? The weird thing sometime it will immediately drop to 90Km and then it will back up again to 110???

The km to empty is a calculation based on many different inputs. It can vary greatly depending on the type of driving you're doing (highway/city, etc) & throttle input. Generally, I think the light comes on with ~100km to empty, but since we don't have diesel Volvo's in North America, I can't be certain on the behaviour of your vehicle.

What may indicate a problem with the fuel level sensors is if that variance was swinging a few 100km, not 10-20km.

hmmm...so you reckon I can still drive 100KM when the fuel light on??? maybe one day I should try to risk, and try to drive see if it does reach 100Km. I just doubt it.

Trip computer is pretty accurate..on all modern Volvo I had/have (5 so far) when light comes on you have (for sure) 2 gallons of reserve...tried and proven on many occasions...

Miles to empty can go up. This measure is re-calculated every 5 seconds based on measured reserve and instant consumption. For instance, during the day, I drive through the heavy city traffic, and MTE go down quickly. Then, at night, I drive home steadily at optimal speed - the number goes up...it is a rather accurate projection of remaining distance, if the engine will operate under the current conditions...

My light comes on at about 50 miles to empty. I have driven the car even after the MTE indicator has simply switched to '---' indicating that I should be stopped dead at the side of the road. Even then, I think there were at least 20 more miles in the tank, but I wasn't on a mission to find out...

This has everything to do with the metric system and its inherent problems:D
is it not the case that the metric benchmark standard ? in paris is decaying and is no longer as accurate?

volvo is fine.........

Just remember, wait until you use the last drop of fuel can damage the fuel pump and alos collect all the dirty stuff inside the tank and delivery to all the fuel lines, rails and injectors. I always fill mines when the light comes in.

You can drive it on -- for a while. I do it all the time. I believe if it is off, then it is telling you it has less than it really has.

Maybe because I realize the fuel line is sucking from the bottom of the tank so any of that nasty stuff has already gone into the filter, and there is nothing to worry about.

well i have seen a lot of different stuff getting "thru" the gas filter on our race cars so i just fill before spend money. BTW the fuel pump heat up really fast without gas around.

Yes, but it isn't as if your going to commute and sit in traffic with no fuel. I buy gas on base and I live 25 min away. We get Esso fuel cards, but good luck finding an Esso the moment you need one. I won't pay $8 a gallon like the Germans, so sometimes it requires running on fumes for a few min to get to the station.

You learn fast to fill up before going anywhere outside the local area.

Not to mention that the fuel helps cool the pump. Filling the tank before it drops under 1/4-1/2 tank can help extend the pump's life.

I was suprised to see my trip odometer reading at 15 miles before empty tank yesterday as the XC(70) was sitting in the parking lot. As I pulled up the inclined ramp it registered 20 miles, and I drove one block to a gas station and put in precisely one gal of gas. The meter than read 50 miles and blinked up to 55 as I pulled out onto the interstate in search of my favorite gas station who sells fuel about 10 cents cheaper than what that one gal cost me. It is a "blinking light" which as you know has other names associated with it, but the double check for you (as I also use) is the fact that i don't (on my particular vehicle) drive much more than 325 miles each time before I fill up. My hand log of fuel fills indicates that is about where my blinking light, needle, and max fill up quantity says I need to be. You know you can always check the max capacity of your tank, fill it up full, and then figure out how much fuel you really had in theire.

regards,
