1. 5/5Great App

   I have no clue why so many folks are having issues. I added my payment account in less than a minute. I pay with ease every time. I even paid for a friends gas at home by then telling me the pump #. I don’t know if any other company yet doing this. I am so happy with this because you get $.10 off per gallon each time! I used to use a combination of gas buddy and shell fuel rewards but this gas is much better (top tier). She’ll is good, but only their premium is a top tier gas. Dinocare is in all levels of their gas. Regular (non high end or sports cars) don’t need high octane gas. It’s actually bad for them, so Sinclair giving $.10 off and offering top tier gas at all levels is a win! I’m not saying folks haven’t experienced issues. It may be that I started using it after they fixed them (started late October 2020), but it also could be user error for these folks. I have had zero issues and it’s been super nice for me.

3. 5/5This really is awesome!

   I actually stumbled upon this getting gas one day. My thoughts were “yeah right” but tried it for the heck of it for the discount they offered in the spot. We’ll it truly is the greatest thing I’ve ever come across as far as getting gas goes! That’s a rather short list but anyway… I fire up the app on my way to the store, log into the pump as I’m pulling in, and I am out three minutes later with a receipt in my email. And to top it all off I get a discount. I don’t typically do reviews, but I had to definitely give this a shout out, because it really is quick and easy app do use, and a great deal on the gas. It allows me to be able to afford ethanol free gas for my car, which makes it run a lot better. So far I have had no “upgrade” requests so I like that as well. It is just a great deal and ultra easy to use.

4. 5/5Mobile Advantage doesn’t work

   I thought this would be a good app. Boy, was I wrong! Mobile Advantage has worked exactly twice. Every time I try to use it as my preferred payment method, I get an error that it couldn’t be used and to try a different payment method. That happens locally and out of town. The two times it worked, I saved 40 cents a gallon. Great. Every time I had to use a different payment, which has been the majority of the time, I got 10 cents off. The Walmart down the street is consistently 30 cents a gallon cheaper than anyplace else in town without the hassle. From now on, when I get the error and have to use a different payment method, I will also be using a different station (Walmart). If I get the error two more times, I will be deleting the app.

5. 5/5Great....when it works about 1% of the time

   This app is the most frustrating app I’ve used. It is an excellent idea if only it would work. The few times that it did work I didn’t get the discount. The many times it did not work was “opps something when wrong” error. Standing next to the gas pump, “your too far from gas station”; goto another Sinclair , still thinks I’m at the other gas station. Prior to this it cleared all my information... name, credit card, etc. re-entered everything and then as soon as I entered the bank card I get a fraud notification from the bank and it says your account it locked. It is one problem after another with this app. Once again great idea I’d only it worked.
