Last tuesday I used my diesel pickup to go pay some bills--had to put in some fuel,so I put in the usual $10 worth,which is around 2.5-3 gallons,and is enough to get me where I need to go and home OK...
I only put in $10 at a time because the fuel tank weeps at the seam if I fill it more than half full...very slow drip,but enough to stink up my garage and be a hazard..
I went to a station where big rigs fill up often,it was on my way--went to put in the fuel,when the pump got to about the $8 mark,the fuel gushed out of the filler neck,some got on my shoes and my coat..
..
I managed to squeeze in the rest of the fuel,but had to wait for it to stop foaming and settle down..
I chalked up the splash back to the high volume fuel pumps they have there,that will probably pump 50 gallons a minute...figured the fuel foamed up,and the tank couldn't burp enough out of the vent to keep up with the flow..
I then went and paid my bills,did some errands,and put about 40 or so miles on the truck...the following Saturday, I went for a ride to get some pallets for firewood,and put another 10 or so miles on it...it was very frigid cold here during these days I used it,so I expected the fuel mileage to be kind of lousy...plus I leave it running while loading the wood...
Yesterday I had to go buy some groceries--so I assumed my $10 worth of fuel I added last week would be long gone or close to it...even if I was getting 20 mpg,(highly doubtfull in this weather)...
So I go to the corner gas station,and put in another $10 worth..
Again,I got to the $8 mark,the pump shuts off,and fuel splashes back out of the filler neck...I tried pulling the trigger on the pump handle ever so gently,hoping to get the rest in,but no--the tank was chock FULL,right up to the gas cap!..
...WTF?...
I know the tank was close to empty not long ago,I felt the engine start starving for fuel on a hill when I was stuck at a red light about a month ago--fuel will run to the back end of the tank when its low of fuel,and let air get sucked in the lines!...and every time since then, I've only added $10 worth at a time,and driven the truck 40 to 60 miles before buying more fuel!..
The only thing I can figure,is I was only using about 1.5 gallons of each $10 "fill up" of 2.5 to 3 gallons,plus the fact the price of fuel has dropped roughly a buck a gallon,so I was getting a bit more fuel for my money...so each time I added more,I was using maybe only half of it--and eventually,the tank got fuller and fuller!...
A pleasant surprise,I must say...but I'm still in awe of how many MPG the old 6.2 must be delivering--even with me driving the truck for at least 30 miles with it refusing to shift out of second gear and winding it out,unless I hit 45 mph,which wasn't possible in most of my trips in it the past 2 weeks,till I got that issue taken care of,in 20 degree or lower temps!...

...haven't got the ambition to drop the tank to change it in this weather--if I ever do,I may as well put a new tank in too..
