What's the optimal way to pump gas?

I always fill up the tank when the marker is at the ¾ mark. That is because gas stations here are few and far between and there are odd and fairly regular power outages. No power, no gas.

The marker is indicating slightly less gas than what is in the tank. In the snowiest parts of the winter, I usually try to keep ½ tank always.

And when I pump, I stand upwind so I don’t breathe the fumes.

Never fill the tank.Just buy a new car!

I’m no engineer, but I usually fill it up around ¼, also.

I’d also heard you shouldn’t let the gas get too low because of sediment in the tank. But I always thought that’s what the fuel filter was for.

pump gas…...inbetween sandwiches…of course

when you are low, when you have money

When I’m on the red and I have a few €‘s

always fill up in the early morning hours.

Hose, bucket, altoids.

I usually fill up at the ¼ tank mark, too, but not always. If I’m not able to get to my preferred gas station (where I get a discount) I’ll just get as much as I need to get where I’m going and back home again. The only thing I’ve heard about doing it efficiency is to pump gas when the temperature is cool, if you can. (I honestly can’t remember why.) That doesn’t usually work out for me, though.

You want to reduce the number of refueling events. Every time you open the cap, you are letting out vapors and increasing the chance of spilling a small amount of fuel.

You can run the tank low. That has no effect on contaminants. There is a filter sock at on the fuel pickup located at the bottom of the tank. All sediment is already there at the bottom. It makes no difference if the tank is full or not.

You should never, ever let the tank run dry. The gears in the fuel pump rely on fuel for lubrication. If you run the pump dry for more than about 20 seconds you damage the pump.

It is best to pump the fuel when it is cooler outside. Fewer vapors are released.

I usually fill up at ½ tank. That way I know I have to put in 10 gal. So if gas is $2.69gal. I know I’m going to spend $27.00 for gas that day. Just one of my little idiosyncrasies

I didn’t know there was a right or wrong way.

I’m all over the map.

Sometimes I top it off and sometimes I wait til the light comes on.

I have it down with my car, when the light comes on I still have a long ways to go.

When the display finally says ‘low’ I still have 40 miles.

Sometimes I push it, sometimes I don’t. lol

I try to go no lower than about ¾. My tank will hold 35 gal. If there is an emergency like no fuel for awhile, I will still be able to make a few trips in an emergency mode. that’s the plan anyway. Plus the fact it costs about 95 bucks to fill it from the bottom, ouch

@woodcutter: 35 gallons? What are you driving? An Amtrak freight train? My Forester takes 15.9. “Ouch” is right.

@gailcalled it’s just a Dodge Ram 1500, 2001 model.V-6 engine. I checked its mileage between fillups and it’s looking like between 15 – 16 mpg. And thats with the a/c always running. I’ve had it almost a month so I’m still getting used to it. It’s the same price whether you fill up the top half or the bottom half :/ My old truck has a 19 gallon tank and it gets approx the same fuel economy and it’s 45 years old.
