How to Find the Cheapest Gas with Your GPS

That sounds cool but how is the Gps going to change the prices everytime the gas goes up or down in the same day I haven't figured that one out yet

It automatically gets updates from MSN.

I have notice that gas stations with the lowest prices seem to always have the lowest or near lowest prices...

These are sites that provide prices:

gasprices.mapquest.com/index.jsp - 29k
www.internetautoguide.com/gas-prices/index.html
autos.msn.com/everyday/gasstations.aspx?zip&src=Netx - 44k

And there are many more.

A lot of these work by drivers posting prices at stations they pass. I also noticed that msn collects the data from 90000 gas stations.

If you google cheap gas you will find these and many others in any area.. Find the lowest price and then hmmm...

That might make a good poi...???

It might - but only for someone with lots of time on their hands as the gas prices are a rather volatile variable, requiring frequent change.

But as I stated if you watch prices in a particular area it seems the same stations have the lowest or near lowest prices. I know the station I buy diesel at isn't always the lowest price but is within at cent or two. So for $.20 a fill-up I don't worry about it.

I guess you are probably right it wouldn’t make a good poi to post, but for a trip, a little research and your own poi might make since…

First you couldn't keep things updated fast enough.
I drove pass a Shell station today on the way to lunch. Price of regular was posted at $4.29 per gallon. 45 minutes later driving pass the same Shell station the price changed to $4.39 per gallon.
It would really be hard to keep thing updated.

Exactly. The stations that have the lowest price *usually* have the lowest price. Usually, but not always.

I get it.

The proposed POI wouldn't be for the actual price, it would be just the stations that typically have the lowest price. That doesn't mean that they would HAVE the lowest price, no matter what it currently is, just historically they have the lowest prices in the area.

Agreed that it would probably not be worth the effort to have a specific poi, but I just added a number of stations I found on gasbuddy.com and motortrend.com to my favorites. These are in larger towns along the routes I'll be taking on a trip we leave on tomorrow. On the interstates or on the state roads, I found stations that had the best price so even though they may be a mile or so out of our way, the prices can be anywhere from 20 to 40 cents per gallon cheaper than the ones I'd see along the roads I'll be taking.

I got the candidates from the gas price websites, copied the address of the ones with the best prices and pasted that into the search on Google Maps. I then sent that poi to my Nuvi 260 and added the following info

Town, State - Name of Station
and in the phone # field I put the price quoted. (Making sure the price is recent.)

When we leave I'll just choose our first fuel stop from my favorites as our destination and hit Go.

Chances are if the prices go up or down before we get there, the stations I chose will still be among the lowest priced ones in that town, so if I end up paying 25 cents more for a fill-up, I can live with that. If the price at the pump is wildly higher than I expect I can always let the unit search for other nearby stations and go to see if their prices are better.
