Why can’t anyone have a station in Middle River Md where there hundreds of boats – Chuck peacherBel Air md (April 12, 2019)

Thanks, Darius, I've updated the box on the home page. As I recall we used to have Petro-Canada 91 on there and someone told me to remove it! – SamSanta Fe (April 15, 2019)
Hello, Many stationd around Madison (WI) now have a sticker on the pump "no ethanol added" and sometimes even state the fuel is for recreational vehicles and small engines. However that sticker is on the premium pump. My question is whether "no ethanol added" is the same as ethanol free. Or is the station being coy and saying this is the gas they carry with the least ethanol and would be your best choice, but its not ethanol free. The choice of words no ethanol added is suspicious to me. – Andrew RichardsonWisconsin (April 18, 2019)
Hi, Andrew. In Wisconsin, "no ethanol added" means E0, ethanol free. Wisconsin has a lot of E0, the most per capita of any state, like at most Kwik Trips (185 in the database currently) and a lot of Citgos (68 right now). As you note, that is almost always the premium grade. – SamSanta Fe (April 18, 2019)
Any doubt? Here's what to do. Buy the Quik Check solution from If it's not a dedicated pump/ dedicated hose, take 2 empty gas jugs. Fill the first one with ~3/4 gal to clear out prior selection. The second jug you'll draw your sample from and report back here. Instant Hero! – pbSTL (April 19, 2019)
Ultramar 91 is no longer ethanol-free, according to this letter: Date: Thu, 11 Apr 2019 at 13:32 Subject: RE : Ultramar Gasolines To: Douglas Ogle

Good Day, Following your email, Yes, we installed stickers on our pumps for the supreme 91’s ethanol content. Our supreme gas contains up to 10% ethanol since February 1st 2019. The decision was made by our supplier since ethanol blended fuels have slightly higher-octane ratings and may result in a slight increase in engine performance, in well-maintained engines. In addition, these fuels also decrease tail-pipe emissions. Thank you, Danya V.

How do you know if a gas station is selling pure gas? Some in my town I’m not sure if they are still selling it. If they do they don’t advertise on their signs. – DavidConway (April 22, 2019)
Thanks, Bob, I've removed Ultramar 91 from the home page Canada box. David - you can easily test the gas with a jar and a Sharpie. Read the "about this site" section here. – SamSanta Fe (April 22, 2019)
Your application is not loading corect maps and stations will not come up like it use to. – Eric BoeILLINOIS (April 24, 2019)
Any ETA on android fix? – MikeKansas (April 25, 2019)
Apparently zero. Jeff just emailed me that the app is back in operation! – SamSanta Fe (April 25, 2019)
I can confirm that the app is up and running on both my phone and my tablet. Thanks! Rick Mozeleski a/k/a – MadFuelerWinston-Salem, NC (April 25, 2019)
I just don't see how to add comments or delete a station. Instructions tell me to hit (details) I can't find that feature. There are 2 stations i found using your app thanks, both of them have limited hours of operation I think adding the hours would help others. Thanks again David – DavidCary nc (May 6, 2019)
I live in California so I'm stuck with E10 gas ever since MTBE was phased out. Those stations that sell pure 100% gasoline: what do they use to reduce knock? MTBE, something else, nothing at all, or, God-forbid, lead? Just wondering. Thank you. – PaulNorwalk, CA (May 6, 2019)
David, if you're trying to use the app to update a station, no go - there is no such function. All database updates are done on the web site. Click a state or province on the bottom of the home page, then on the resulting list of stations you'll see a "details" link in the rightmost column. – SamSanta Fe (May 7, 2019)
@Paul, they don't use anything to reduce knock. It's 100% pure gas. However, knocking typically happens at lower octane levels, so use 90 octane or above when you can find it to prevent knocking. Also, you could try adding a few ounces of Marvel Mystery Oil to each fill up/tank of E0 Gas to help in place of the lead/other additives. – JasonAAtlanta, GA (May 8, 2019)
@Paul, I also found this online: If you're talking about the exact formula of the gasoline, looks like they add a higher concentration of BTEX (benzene), xylene, ethyl-benzene, and/or toluene to raise octane levels. Although these compounds have been shown in some studies to be potentially harmful, they're less toxic than lead. – JasonAAtanta, GA (May 8, 2019)
Excellent resource. Absolutely essential for vintage Enduro 2 stroke motorcycles. The person I purchased my bike from used $12/gal racing fuel. He lived in Iowa and road it occasionally. Thank you for the web site. – Charles FranciscoMahomet, IL (May 8, 2019)
