What do you think of the following fill strategy?

1. When prices are INCREASING, fill up as often as convenient. I don't go out of my way to fill up, but I fill up as often as I can (typically at 3/4 tank or above). Fill up now since tomorrow's price will be higher.

2. When prices are DECREASING, fill up only when the tank is low (typically less than 1/4 tank). Put off filling up as much as possible since tomorrow's price will be cheaper than today's price.

3. When prices are STABLE, fill up only when passing by my preferred low cost station. (Don't waste gas to go find gas.)

Does anyone else follow such a strategy?

According to dollar-cost averaging, buying a full tank when the prices are dropping is better than buying a full tank when prices are rising. Keeping the tank full when prices are rising means smaller purchases and less price per gallon differences. Buying a full tank when prices are dropping gets you the full benefit of lower prices. Needless to say you aren't going to get rich doing this, but you can save $100-150 per year.

Prices on the futures markets continue to trend down. Delay, delay, delay. The gas you buy tomorrow will be cheaper than that of today.

wes03 - I don't know what futures you've been looking at but gas futures dropped 28 cents a gallon this last week on nymex and oil dropped almost $4 a barrel.

As gas prices drop, you may consider filling up gas containers too. But be sure to add gas stabilizers if you plan to store the gas containers for several weeks. Gas will go rancid and will decrease engine efficiency.

Knowingly the more fuel one burns up, the more often one can fill the tank, exciting, for any money spender! They won't get bored, try again, stay "Happy" your promoting success! Any way you choose to fill is still about how you drain it out, so know what you are doing about that... Real simple! HAGD! Remember....>>> Draining it out.

I wholeheartedly agree with Member "heyman_31036" answer, QUOTING: "I use GasBuddy relative to my trips and buy opportunistically as needed."

I check GB for the best prices and we have our own network for prices. I buy when stations, such as the local Shells (Top Tier) have promotions like "20¢ Off Premium Tuesdays" and "5¢ Off All Grades Thursdays". I couple that with Fuel Rewards and Kroger Rewards for the best discount.

I like to keep the tank above 2/3 when local, especially in Cold Weather. It prevents condensation in cold and increased ethanol vapor pressure in hot. In addition, all your modern fuel tanks have the Sender Unit -- combines a small, hard-working fuel pump and the tank level gauge into one module -- designed to be bathed in gasoline. The gas is the coolant for the fuel pump, which can get very warm.

The refuel stations I use the most are near where I generally shop the most on a regular basis. Three-four miles away, they have frequently the lowest gas prices of our other areas.

That price can vary by many cents per gal but not always. Some pumps are more favorable to use if rounding off $ amounts. When the fuel price is lower I often fill some utility containers also at the same time, then nearly $5.00 is saved at times.

If a closer station drops to the lower price I take advantage of the closer distance whenever, Rain/shine, ETC. any vehicle for a near 65% added top off. WFM!

Since most of my driving is short distance in zones up to 50MPH. and there are numerous stations handy,I stay at 1/3...1/2 tank normally, less weight.

I seldom top off real full during Summer because of fuel expansion in my tank. My closed evap. system often purges excess fuel vapors from splashed gas in the tank which gets mixed with air as the tank reduces in levels. The ECM allows this at different times, engine burns the excess as part of its OEM mapped programming/balance, often the RPM tack shows this during hot seasons only at idle mostly, when with normal operation engine temps.

As many have noted, mostly this is a waste of time and energy. However: I used to go with dollar cost averaging, most often used in investing. You could do this here, by paying the same amount each fill up, say $30. When gas is low you will get more gallons. When gas is high, you will be buying less gallons. Therefore, on average paying less per gallon, no matter how the price fluncuates.

1/3 to 1/2 is better for my driving style. Fuel price changes determine when I top off my tank or tanks. Never have run on empty yet!

Use the GasBuddy Web Site and app... watch for the gas prices to be trending down, and jump on a low price anytime you see one.

Best bet - If there is a story on this site about gas prices going down, you can bet that prices will go up the next day. In Cleveland, we're 32 for 32 so far in 2014 when these stories pop up!

I always wait as long as I can and fill up just before the price goes up. Thanks to Gas Buddy that lets me know when prices are about to go up. With a full tank of gas I can usually ride it out till the price is back down again.

The savings depend upon the luck of your gas tank level, and your ability to accurately predict price changes, both of which are uncertain for most of us.

Another factor is perhaps more important here. Don't run a low fuel level; you never know when you are going to need the gasoline in your tank. If some natural disaster strikes, and there are continually reports of same throughout the US, you could be stuck with an almost empty tank and no chance to refuel.

Here in southern California, the dominant risk is an earthquake. A strong earthquake will cut off nearly any drive of more than a few miles from one's home, plus, there won't the be electricity needed to operate the pumps in the gas stations. Would you want to be stuck with a tank on empty in such a situation?

Suppose that your wife or teenage daughter had an accident and needs a fast trip to the hospital emergency room? Would you want to stop to get gas for that?

If you are old enough to have some real life experience, you will understand that there are a myriad of reasons why it is smart to never let your tank get below half full. Protecting against these outweighs the few cents that you can save on a gallon of gas. Think about it.

It depends, I fill up once a week. The rise and fall of gas prices makes a couple of dollars difference either way. Since I drive an F-150, driving 10-15 miles to save a couple of cents per gallon costs me more money than it's worth. I usually plan my gas buying for trips that take me close to the lowest prices in the area.

Sometimes people go nuts over a few cents. If you have a 20 gallon tank and the price goes up 5 cents, that's a whole dollar more to fill your tank. Is it really worth it to drive half way across town to save a dollar?

For the next trip to Nebraska in June, I will go between Huntsville to Lincoln Sam's Clubs (880 miles apart) with only one gas stop in the cheap gas price area of central Mo. The Hybrid Camry posts a typical 670 miles as the range on fuel left when it is filled up (17 gal tank and 45 MPG on Interstate at 60 to 65 MPH, while still leaving 2 gal in the tank as reserve. The car Nav calls out the gas prices at each exit based on the shortest distance first between the car and the gas stations.
The cheapest gas today is like 3.31 around Sedilia, Mo according to this site. AlabamaGasPrices make a good site for planning purposes.
