Mine too. My guess is that when we fill our tanks, we fill them above the upper limit of the float. If the tank is being filled above the upper limit of the float, the gas above it must all be used before the float even begins to move down and the needle moves off of 'F'. That makes the first half of the tank seem to go more slowly than the second half.

I haven't had an F150 fuel tank apart before. Anyone seen (or have pics of) the float?

(Love the new fuel/wallet gauge, btw. Glad my other vehicle gets ~28 mpg!)

 

In a way, I like the slow needle drop feature. It still gives me hope that I'll get more than 12 mpg.

 

Ford does that to promote sales on demo models. That way the salesman can say it's gone 250 miles on only HALF A TANK with a 5.4 engine... Consumer proceeds to flip over what awesome mileage, and buys the truck. Next day they realize there is only 50 miles on the second half....oh well.

Our 07 Explorer doesn't do this. Gauge there seems to be pretty static in it's rate of decent. But my '93 is like that. Moreso for the front tank than the rear.

Funny, my boat and jetski are just the opposite. Drops like a rock to half, then trickles down the rest of the way.

 

I had 2 S-10's before this and they all did the same thing. Slow the first half and fast the second. I learned along time ago to use the trip odometer. I have only had 4 tank fulls so far and get 20.5 to 21.8. mpg. 25 miles each way to work and all 2 lane road.

 

Same here... I filled up last sunday, to and from work all week and today I have 1/2 tank. I went to the carwash and back, same distance as to work and back, and Now I have 1/4... I use 1/2 tank in 5 days, and 1/4 tank driving to town???

 

thank you for understanding what i was saying

 

Tell me you're kidding?

For starters, VERY very few new cars come even close to that mileage before being sold, and used cars....well, are you kidding? It just doesn't work that way.

I worked at a dealership, and I know fully well that the cars come from Ford with a few gallons, and rarely get refilled at a good dealer. If they do, they get typically $5-10.00 worth of gas while on the lot... so that entire concept wouldn't work.

Well, at any rate, I sure hope it was a joke

 

I don't know about you, but I would expect the gauge to indicate the capacity of the tank, not the physical level of the gas in it. Why would anyone care about the level, especially with hills and such ? 1/2 tank should indicate 12.5 gallons of fuel in my truck - nothing else.

The tank is NOT V-shaped at all - I've had several of them out doing fuel pump upgrades. It is long and rectangular in shape. (2WD versions anyway)

With a rectangular tank and a sending unit that travels vertically, the gauge should read accurately... BUT -

We have a winner !!!!!

Use the odometer - I am always amazed at how consistent my mileage is, as long as I don't run it way faster than usual.

 

I've owned perhaps 20 vehicles in my life (not all Fords), and the gas gauges all do the same thing. I go by total miles driven.

When you fill it up, the level of fuel is actually above the float (well, many newer cars don't have a float, they have a capacitance induction sensor as used in aircraft). You probably have a gallon or two in the fill pipe, and then you have to burn off a gallon or two in the tank before the float can move.

 

Like i said, its not exactly a \ / shape, but yes there are steps in the back of the bottom. Dont make me go crawl under my truck and take pictures...

Trust me the gas gauge is accurate.

 

haha they are called baffles.. they keep the fuel from shifting so much going over bumps.

 

wasnt talking about the baffles, but okay
