If gas goes under $2, I'm buying a 200 gallon fish tank and filling that ***** up.

I was surprised when I went thru Ames yesterday they were actually competitive with other towns.
And this morning I see those same "down 5 cents" places are now up 15 cents from yesterday. Someone in the business must read CF and not want to be known for low gas prices. Wondering about tomorrow because I'll need to fill up soon.

I will certainly look at trends for which station is cheaper on average and just fill up there most of the time. Having competing stations across the street from each other seems to help. In Cedar Falls, the Casey’s seem to be a bit more expensive than the Kwik Stars. I don’t shop at HyVee, so maybe those discounts offset that difference?

Ethyl Alcohol has about 30% less energy than gasoline so if you are buying 10% ethanol you should be paying 3% less to break even over the 100% gasoline. For $3.00 gasoline it should be a savings of at least $0.09 to break even. Any additional savings is gravy. This is ignoring the benefits of higher octane of the ethanol blends.

This goes for comparing E-10 to E-15 as well. There the difference is 5% alcohol so 30% reduction in energy times only 5% of the volume is only 1.5% reduction in energy per gallon. So if you are paying $3.00 for E-10 you should be paying $0.045 less for E-15 to make it worth your while.

E-85 is a little more difficult to find fuel that is cost effective since there is generally 75% more ethanol than E-10 so it is 22.5% less energy than the E-10. if E-10 is $3.00 you better be saving at least $0.675 to break even. Note that in the winter months the mix is more likely 70% ethanol rather than 85% due to the difficulty with vaporizing ethanol at lower temperatures. This means you have more energy in "E-85" in winter. Winter savings should be around 18% which is about $0.54 in our $3.00 E-10 example.

I was kind of burned on E-85 in the past though. I bought a vehicle in the aughts that was flex fuel so I ran E-85 in it when I could. I ended up with engine problems though after long term use (a decade or so). The kicker was that there was a manufacturer notice that went out about it cautioning against going back and forth between mixes that I never saw. It went out to dealers a few months before I bought the vehicle but they never provided it to us when we bought the vehicle, nor did they tell us about when we were back for service. The owners manual touted being able to go back and forth between mixes without restriction or adverse effects. That experience makes me pretty nervous about too much going back and forth between mixes.

Also, never ever buy E-85 in the coldest months. I'm not sure what the breakover temperature is, but in our experience some below-zero temps will make it very difficult to start your vehicle running that fuel.

I don't know what constitutes winter blends in gasoline. My wife got a new Accord this spring and has consistently gotten 40 mpg using E10, but for the last couple months only can get 37 in similar mixed driving.

Why is it stupid to save a few bucks with the only effort being to ask if the gas there is cheaper? Be different if they were planning their day around it or going out of their way.

That's like having access to an online coupon code but just choosing not to use it. No, it's not going to "break me" by not using it, but why not?

I guess I view my more valuable than worrying about saving $3 on a tank of gas (15 gallons x $.20).

It's the same reason I can't go grocery shopping with my wife, she wastes so much time trying to find deals and checking the receipt to save a whopping $10.

Yeah, the gas thing makes no sense. what you would "save" in $$ traveling to another gas station would be loss in the amount of gas it took you to get there.

In the situation he's referring to, his family asks him what central Iowa gas prices are before they travel there... as someone else pointed out, that's likely so they can decide to either fill up before leaving home/when getting back home, OR leave just enough in the tank to get to central Iowa, and fill up with the cheaper gas there..

You're filling up either way, might as well use the cheaper of the two options if you're gonna be in both locations anyway. There's no additional traveling happening in that scenario. I agree, no sense in going out of your way/spending extra time to save a couple bucks, but this isn't that.

Does it work to just alternate putting in half a tank of 91 then half a tank of 85 on alternating visits to the station so you are mixing half a tank of the high octane with half a tank of the low octane?
It would work but I'm not going to that trouble when there's a Conoco across the street!
Our RAV4 has close to a 20.
I'm a Toyota nerd. The largest tank ever offered on a RAV4 is 15.9. If you've put 15 in, you're either cutting it really close or someone's pumps are ripping people off.

I notice the price when I'm filling up but if some other station was $.20 cheaper that is less than $3 and not worth the effort of researching it. I don't get why people are so fixated on gas prices and then do stuff like spend $8 for a coffee.
I have a cousin that does this. Always complaining about gas prices and feels we are entitled to cheaper gas, yet he drives a Suburban and he and his wife are empty nesters and have a 5000+ square foot home.

I don't know how real this is, but if it is real this person is really dumb (obviously). I am also surprised a store would allow that. My roommate in college ran out of gas on his way to the gas station (he would always tow the line of running out), and walked to the station, put some gas in a soda bottle so he can get enough in the tank to get to the station, and the station workers can out and chewed his ass. They forced him to buy a gas container and use that instead. Smart of them to do that of course.

Unless you're not going out of your way for it and there's a difference in places on the path you intend to travel.

Gas is ALWAYS cheaper in Des Moines than northeast Iowa. If I'm going down to Des Moines, and I have enough gas in my tank to get there without filling, I won't fill until I get down there. Why would I just pay the extra money with no good reason to do so?

Have you seen today's crop of gas station employees (especially most Casey's locations)?? I don't think most would even notice, let alone take the time/effort to go out & stop anyone from doing that.
