Re: Gas light question?

Ok....EVIC tripped LOW FUEL at 40 miles till empty......reading 9.8 MPG. So in theory, around 4 gallons left in the tank.

Re: Gas light question?

Maybe it trips based on a "range" left from current mpg... so When ever it calculates that you have 40miles (random distance) till the tank is bone dry it chimes...

Here's the other shoe dropping. There are several capacities on the various WK years, so check your owner's manual to see listed fuel capacity.

The 11% is the total volume left, but I do not believe all of the remainder is usable, because the tank is not absolutely flat on the bottom and the pump needs to be flooded at the suction. The likely usable volume is probably 18.5-19.0 gallons.

I once drove mine way farther than I should have because there were no gas stations on a rural road. Not only did the light come on, but the EVIC refused to display any miles until empty, just "low fuel". Took about 18.6 gallons to fill it (and 2 minutes for me to release the suction on my seat).

Last week Highway milage tripped at 10 mte and EVIC said I was at 16.9mpg. This week I'm in The City and it tripped at 10 mte and EVIC said I was at 8.3mpg. Both times I put 16.5-17.5 Gal in to fill. Manual says I have a 21.1 Gal fuel tank. Yes it's a dog in The City, but oh so much fun

Yeah, my Gas gauge was on E last week, 55 miles til empty and it took 16 to fill it up. So there was still 5gal in the tank. I guess the Gauge must be off some...I guess its better to be off that way than the other way.

Yeah, I have seen the 8-9 MPG especially with the AC on this week.....Its swear I can hear the pennies dropping out of the exhuast as I drive along.

Re: Gas light question?

I've had mine trip and my DTE was already 0 when towing my boat (Tow/Haul on), but still had over 4gal left. I've never once put more than 18.5 in the tank even after driving well past 'E'.

It does not appear to be directly related to volume of gas in the tank with all the inconsistency. It seems to trip when the EVIC shows around 10 MTE under most normal circumstances.

That being said, it appears that the warning comes on when you need to fill up anyway. Not because of crud in the tank, but strain on the fuel system. When it's low enough, if you were on the right incline (or created enough sloshing), the pump could be hit or miss and try to pump air through the lines, this is bad for all parts involved. In essence, you always want the pickup fully submerged to have proper operation.

Everyone keep an eye on it and post these 4 things to figure it out better.
DTE, MPG, mileage you drove until filling up, & how many gallons for a fill up.

Doesn't do much good to say something like, "10 miles DTE, 12.7mpg, 17.138 gallons" if you drove 35 miles after it came on. Like I said, I've driven well past 0 miles DTE and still had a few gallons to spare. I've grown numb to the gas pump and stopped paying close attention, but will again now. I started treating the Hemi like a gun and reload often just in case...

Re: Gas light question?

My EVIC showed about 65 MTE while driving. I stopped on a steep hill for about 2 minutes, and the MTE dropped to under 35. about 41 is when the light came on. EVIC shows 18.1 mpg (daily driver, lots of highway).
