Gas MPG
 

Has anyone ever noticed you get better miles per gallon when you only fill your tank halfway each time instead of feeling it all the way full. When i fill my tank halfway i can go 160 miles. And when I fill it all the way up, it goes 250 to 275. Must be the weight of the gas in the tank, making your engine work harder, I dont know.

Eh, its just the inaccuracy of the gauge shining through.. I usually only fill up $10-15 then like a day later running on the check gauge light for a few miles.. I almost ran out of gas the other night, my truck started puttering- luckily I was a couple blocks from a gas station. I'll be filling up a little more each time when I get payday rolls around.. A friend of mine did tell me that it's better to just fill up all the way, instead of a little at a time- I need to start doing this for the sake of my fuel pump! lol

It might look that way, but it isn't actually happening. There is no accurate way to know how mcuh fuel is in your tank other than full and empty. Full because the pump stops and empty because the truck stops.

I noticed that my 3.Ohhh... Does best and seems most efficient (smoothest ride, best handling) at 70 MPH with half a tank of gas, or at least half a tank on the fuel gauge. On a full gauge at 70, it handles unevenly with the weight of the tank on the left side of the truck, but at half a tank things seem to balance. Beats me, that's for the engineers.

there is no noticeable difference weather my tank is full or not in the performance or handling of my truck

I think its all in your head, I fill it full when its empty, but that's just me

Agree I can't see how that little weight would make a difference. What are we really talking about 20 lbs ? Now if you find a way to remove a few hundred lbs i could understand.

1 gallon of gasoline equals 5.8 to 6.5 lbs. so lets say if you are ten gallons down that's 60 pounds give or take. Not a big enough deal to make a difference.

I dunno but my gas tank would probably be more than 20lbs when full.. anyways my a/c makes a bigger difference in performance than a full tank- hopefully the e-fan will help with that one..

regardless of what people say, its almost totally dead flat in my driveway, and i know where my mileage should be regarding where my needles is. that being said, this past tank im at OVER 200 miles and still have a lil less than half a tank left! beat that, thats like 21-22 mpg
