We start our winter blends in October and haven't had anyone complain yet. And I'll admit, I've yet to run any antigel in my tank.
I'll agree, sounds like a bad tank of fuel.. even though everything is suppose to be sealed, wouldn't be surprised if water front he ground got in. Also, per the State of NH, all of the fill areas are not supposed to have drains in them. Several years back, stations were allowed to have little syphon drains, you'd pull a little chain and the water around the neck of the fill area would drain into the tank. These as of a few years ago were required to be removed and sealed not allowing water to get in.
Depending on the station, it is possible they never did this and during the winter, drop the water in.
Unless there is a breach in the tanker truck, typically if one station gets bad fuel, it will be bad across many because it comes from the same port.

I've read that both the pm23 and fuel need to be above freezing for the anti-gel chemical reaction to occur properly. If you keep the pm23 above freezing and add it right when filling from an underground tank, it should work.

Thank you 2009kr. You are exactly right...says so right on the bottle. I got the truck running and up to my heated shop where it fits (won’t fit in my garage). I am leaving it there for 3 or 4 hours and then will add warm pm23 and take for a drive.

I'd drain a few ounces out of your separator as well.

There is nothing wrong with Cumberland Farms. And Citgo.. their gas isn't Citgo branded. The Citgo stations just like any other station buy from whatever is cheapest at the port at that particular day/time.

I’ve had nothing but good luck with Cumbys diesel, definitely a high-volume station. City DPW is filling there now too. But I’ve heard negative things about Cumberland Farms gas, especially when it was labeled Gulf.

Just my thoughts..... If someone were on the road traveling cross country during the winter months as in like, right now.... How is one going to get their truck heated up in a heated environment just to get the diesel fuel and PM23 warmed up?

Well 2 scenarios that I can think of. I keep my PM23 in my truck so it is warm (dump it in when fueling up). And the fuel in the ground is typically high 40s to mid 50s depending on the time of year. So above freezing fuel going into the tank with cab warm PM23 being dumped in.

I thought there was a fuel warmer/cooler? Wouldnt this make the fuel on the return line to the tank keeping the tank fuel somewhat warm? If so wouldnt that debunk all theories on the Additive mixing, maybe I misunderstood the warmer/cooler thing...

This is from page 178 of my manual regarding the fuel warmer.
Your vehicle has a fuel and water separator
that recirculates fuel from the engine to
help prevent fuel filter clogging. To avoid
engine fuel starvation during cold weather
operation of 32°F (0°C) or below, we
recommend that the fuel level in your tank
should not drop below 1⁄4 full. This helps
prevent air from entering the fuel system
and stalling the engine.
