Seriously this is horrible, I put $20 and 1 hr later, the truck is back on Empty???

Its an 01 5.9 with about a 3in lift with 33" tires. 8-10 cant be normal, plugs, wires are newer. I use 87 and sometimes 89 octane, any advice?

 

Sounds about right. Check out this thread: https://dodgeforum.com/forum/2nd-gen...rs-addons.html

There are some real easy solutions like "pushing it" and "using a girl friend's car" but there are also some interesting points. Sadly you will see you will have to spend money to save money.

By the way... I drive my wife's jetta most of the time.

 

Do you have the death flash and a blown plenum? That might be causing your bad mpg's. I average about 13 mpg. I have a 3" lift with 33's

 

I read about the death flash a little but still dont really understand it, what exactly is it??

 

thats about what i get(i also have 3in lift, 33-1250s,15s with steel wheels) and i also have a topper, 250lb steel bumper, 100lb winch, and about 700lb in the back end at all times.... (my truck usually weighs between 6500(at a min) to 7400lb... I also drive it hard.

 

Sorry to chime in again so early but... I was thinking $20 really isn't much. In CT, we're at $3.20/gal for 87. I think it cost me $60ish to fill up last time.

I also seem to recall something about the rams having a 4-5 gallon "reserve"... as in when your gauge says you're empty, you have about 4 gals left. You'll want to verify that before you depend on it though.

 

I dont mean $20 to fill it up, just putting $20 in the tank as an example

 

My walk light comes on when my gauge says I still have 1/8th of a tank left. That seems a little strange to me. But then again, I'm used to Chevy's.

 

Don't quote me on this, but from what I understand is that it was Dodge's fix to the plenum issue of these trucks. Once they realized that the plenum gaskets were blowing and causing pinging and major oil consumption on the magnum motors...instead of issueing a recall that would have cost $$$$$$... they decided to "reflash" the computer on these trucks which changed the timing. This resulted in crappy mpg's and loss of power, but helped with the plenum leak.

Since you have a 2001, it's a good chance you have the deathflash. I believe if it was...you should have a sticker somewhere under the hood saying so.

To fix this you can buy a programer... Sct, Superchips, or hypertech.

 

I know you didn't mean $20 would fill it but if you were on "empty", depending on how much of that "reserve" you used, $20 won't get you far up the gauge. 4 gallons at $3 each = $12 just to get the light off. That means you have less than 3 gallons above. Depending on how you drive and your mods... yup, I can see you being back on empty in an hour.

And about the deathflash... I think it was also to compensate for the trannies being on the weak side.

Regardless... once you change your blinker fluid, you should be ok!
