How much fuel do we have once the needle is completely down ?
I was wondering, how much fuel do we still have once the needle is completely down... as in it won't get up at all when turning the key to ON ? Mine is there right now... I'm out of money, and theres a cheque going to Ross' for a lot of stuff for the car .
when my fuel light comes on, my EVIC says 20 miles to empty...once i've ran it until the EVIC said 0miles to empty...for 20 miles It was a need to do situation but now I know once the EVIC says 0zero you still have a good 20 miles or so of careful driving.
When my fuel light came on, the OTIS always went to 0 DTE. The owner's manual says the light comes on when there is 2 gallons left. However, based on the book it has a 17 gallon tank. The very first time my light came on after I bought the car I was on my way to get gas and didn't take 14 gallons to fill it back up, so I don't think that 2 gallons left is very accurate.
I just had the OTIS installed (thanks Ross) and the gas gauge idiot light went on with DTE of 41. I ran out of gas once on my old trep (2000 SE), and it caused all kinds of misfire codes (not a big deal) but the real problem came in the months ahead as my fuel filter became clogged. If you're like me, then bad luck follows you around - in which case, I'd suggest you at least a few bucks in there just to keep the dirt from becoming too concentrated to clog your filter!
You can not use the DTE to determine how much futher you can drive. It's only an estimate and the estimate is based on previous averages.
I and I'm sure you have too. Driven and actually increased the DTE when driving "efficiently".
The best guess would be to drive it to the pin. Drive it further and note the miles/kilometers. Then fill it up. Noting the gallons or Litres to fill. You can next time calculate a better distance beyond the pin.
While I agree with Yiranhu's theory about driving on low being hard on the fuel pump.
This may be a case of one pump will last 20 years and 400,000 or 20.1 years and 401,000. Fuel to cool the pump is the idea but I drive to the pin EVERY tankful. Every car I've owned and own. Never lost a fuel pump yet. So it sounds like a good idea but I wouldn't sweat the difference.
