Hi all,<br>
<br>
I thought you'd like to see these gas saving tips I found in a Popular Mechanics article while reading blogs about gauges. They are interesting and some are counter intuitive.<br>
<br>

<br>
1) Coast to a stop whenever possible and safe. The less you brake, the better your mileage.<br>
<br>
2) Don't accelerate too slowly or too quickly. Doing either keeps the transmission in lower less fuel efficient gears. Take about 15 seconds to get to 50 mph.<br>
<br>
3) Close windows and keep AC on to keep cool at 60 mph and over. Aerodynamic drag costs you otherwise.<br>
<br>
4) Cruise at lower speed, if safe. Test car - 40 MPH - 29 MPG; 60 MPH - 26 MPG; 80 MPH - 21 MPG.<br>
<br>
5) Coast down and up hills if safe and don't try to maintain constant speed.<br>
<br>
6) When coasting down hill, leave the car in gear. Many cars will disable the fuel injectors. Idling in neutral burns more fuel.<br>
<br>
Other misc tips: monitor tire pressure, plan and combine errands, spend as much time as possible with engine warm - go to farthest of several small stops first, make right turns only so you spend less time waiting on traffic, avoid ethanol (relevant to this thread).<br>
<br>
Sincerely,<br>
<br>
Ron<br>

Nice sites. Thanks. Not much help to me though. No pure 87 octane anywhere near me. Larger cities are most notably missing from the lists.<br>

Ah, the second one is exactly what I needed! I had been looking around on the first one, but as you noted, was not familiar enough with the little town names.<br>
The collective knowledge and usefulness of the info on this list once again is proven ;)<br>
Ethanol free is all I use in my mowers, tillers, etc..., and I have been trying to use it exclusively in my Jeep.<br>
I made an observation a few years back regarding this topic.<br>
Before the current vehicle, I had a 2008 Volvo S60 2.5T. At the time, I was dating someone near Pensacola. If I filled up the car with ethanol free gas, I could drive down, park my car at her place/ride with her for the weekend, get in the car, and drive back on one tank of gas. The light would come on just before I came into Tuscaloosa. If I used ethanol gas, that light would come on about 30-40 miles south of town. I repeated this experiment several times with near-identical results.<br>

At least two different web sites track stations that sell real gas.<br>

Have used the first though the second may be more useful to an out of town'er<br>
not familiar with city names. Oh, anyone not aware of the difference.<br>
lawnmowers, weedeaters and chainsaws love real gas. And you can safely leave<br>
it in the tank at the end of the season unlike ethanol which will fill an<br>
aluminum carburetor full of white sludge.<br>

I'm going to be coming over to Atlanta for a week (Sunday 22nd to Friday<br>
27th), and I was wondering if anyone knows of a gas station in the Atlanta<br>
area with ethanol-free gasoline? From what I can find online, it looks<br>
like there is one place in Douglasville and one place in Marietta, but I<br>
don't see anything listed any closer. My vehicle burns the ethanol stuff<br>
just fine, but I prefer to use non-ethanol when I can. I'll be coming in<br>
on 20 from the west, and taking 285 up to the Sandy Springs/Dunwoody area.<br>
I don't mind driving a bit out of the way if necessary.<br>
