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?

Gasoline futures have been rising for about a week and now increases are showing up at the pump. Get 'em filled.

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.

I don't. To me, spending the extra time is just not worth it to save $2-3 over a couple weeks at the very most.

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.

I fill when prices are low and avoid filling when prices are high. I drive a diesel, so my filling intervals are longer. I bought a diesel caddy so when prices are low I try to get an extra 30gals of low priced fuel. Last time I filled up, I used a $1.00 off per gal at Shell by getting a 5qt. jug of Pennzoil. The code under the cap was plugged into my FRN loyalty card and they allowed 20 gals with $1.00 off resulting in $20.00 savings. Also Vons and Ralph's grocery stores give 10 cents to $3.00 off per gallon depending on how much you spend on food. I get $0.50 off per gallon at Chevron when I don't use my FRN card. I keep a fuel/mileage log and estimating the cost of fuel without loyalty/discounts I save an average of $800 driving 36K mi per year.

Pinbuster2005 - "it's a waist of time to stop at the gas station every day or two and get $20 worth of gas."

I don't recall recommending stopping at a gas station every day or two. BTW you wear a belt around your "waist" and you waste money paying top dollar for gas.

"Your still spending the same amount of money."

Not if you are aware of what the futures prices are doing on the commodities markets. BTW your and you're sound the same but have different meanings. You can look it up.

wes03 - "That said, I hope someday to be as rich as you where I don't care how much stuff costs, I just buy it. "

Ok I have to agree with sneakers first of all it's a waist of time to stop at the gas station every day or two and get $20 worth of gas.

Weso3 it's not about being rich. If you stop and think about it are you really saving anything going to the gas station every couple of days? In my case unless I've got to go into town i'm going to lower my fuel economy by either going into my town to stop at the gas station or go into the city I work in to stop at the gas station rather than get right on the highway (55 mph road or better). Granted I will admit by just filling up once a week I have missed price decreases but I would say I've missed just as many price increases. Also really whats the difference going to the gas station 2-3 times a week and getting $20 in gas or just going once a week and getting $40-$60 worth and filling up. Your still spending the same amount of money.

Sneakers55 - You are so correct. Maryland is a tax and spend Democrat controlled state that has basically evolved into a one party rule situation. Huge numbers of the folks here are on entitlements or are government employees and keep voting them in. It's ugly.

That said, I hope someday to be as rich as you where I don't care how much stuff costs, I just buy it.

No, I don't follow that strategy.
1. I fill up gas tank in full when it went down to the lowest price because there is a cycle. Every 2 or 3 weeks, it goes down to low prices in Ontario.
2. Or, if I have to fill it up because tank is near empty when prices are high, I just fill small amount (less than 20 L) and wait for low price cycle.

I have better things to do with my life than topping off every day to maybe save a few pennies.

Besides, Maryland is a blue state which means state fuel taxes are what's rising at warp speed.

The area around Johnson Space Center in Houston has had their prices go down over the past several days.
