hellllo,
so i have a 2017 wrx and i live in Edmonton Alberta Canada where temperatures can reach -30 Celcius. well today i went to fill up gas and the lid was frozen shut. does anyone else have this problem? if so, what did you do to help it? as well the doors get pretty stuck when trying to open in the morning so thats a thing. i believe i should use some sort of De-icer or lube for my doors and possibly my gas lid? any suggestions on that to use? the gas lid is all paint so i want something that wont be eating away at the paint. as well, what does anyone recommend for start up? i mean idleing these new cars for too long isnt great, but at -30, you pretty well need to warm it up for 15 minutes.

2016 WRX- I've had that here in Minnesota, the gas lid was just iced over, I think I stuck a credit card or key in there to pry it ever so gently. Do my best to keep it dry going forward.
The idle does seem to take forever to drop down to 1k RPM's, not sure what that's all about, so it's going to get warmed up in the driveway for a few.
good luck! John

yeah i didnt have to fight tooo hard with the gas cap lid, but i noticed inside that some plastic pieces look separated from their clips or something. im going to see if subaru will help a brother out if it comes time for replacement. to me, thats an overlooked feature that isnt my fault. i mean if there was a part that was lifted so you could get a finger in there like most vehicles have than it wouldnt be an issue. but noooo they need to keep it all flush haha screwing us winterites over. yeah i hate running my vehicle for long periods of time on idle but i think getting up and going right away in -30 would be even worse for the vehicle! sometimes i wish i didnt have a new car so that my paranoia wouldnt bother me haha

Mine does it if we have a wet day and a cold night. Make sure your door seals are dry and clean that should help with the door. I can't think of a way to stop the fuel door to keep from freezing though. It's why I hate not having one that opens from the outside.

Your idle is going to be higher for longer when it's cold because it doesn't start to drop until 100f or something. The colder it is the longer it takes the coolant temp to come up to that mark. Coupled with the defroster that's probably on it can take a bit.

I cup my hands over such frozen things and blow on them to defrost. I also let my car warm up only until the TGVs open full, then I go and brap the gas pedal once and the idle comes down off the 2k high idle.

pour a bunch of water on the fuel door, sure it will freeze again but it will let it open temporarily, as long as its not super cold... the coldest air temperature ive ever felt is 16f so i have no idea if that will still work for -30c...

Get one of those standard spray bottles.

Fill as follows:
1/3 Tap Water
2/3 Isopropyl Alcohol

You could adjust the mixture and use a bit more water (50/50) and use a few drops of dish detergent as a surfactant as well.

^^ This. Distilled water is ever better - no mineral deposits. Dish detergent? Why?

Do you wash your car with distilled water? If not, unless you keep a steady supply of distilled water (e.g., water/meth system), I wouldn't worry about it.

Dish soap or baby shampoo acts as a surfactant, or wetting agent.

Wikipedia:
https://en.wikipedia.org/wiki/Surfactant
https://en.wikipedia.org/wiki/Wetting




Layman's Terms: It helps the spray "stick" to the ice vs just bead up and/or slide off.

NOTE (not related to cars, but to this post): If spraying liquid weed control in your lawn, consider introducing a surfactant like baby shampoo into the mixture, for better results. The surfactant will help the liquid spread evenly over the plant vs beading up (therefore, applying greater coverage area to the chemical that kills the plant).

Ah, got it. I usually have some distilled water around, so I suggested that.

Between acid rain and the minerals in the water when you wash your car, I don't know why you'd bother with distilled water in something like this.

I certainly understand there are situations you absolutely want to use distilled water, where minerals and such could clog up a system (e.g., you DO NOT want a water/methanol injection system to fail due to a clog), but water with minerals on it getting on your paint? Meh. Save the hassle of buying/transporting/storing distilled water for where it's really needed, IMO.

Certainly, distilled water in your mixture is not a bad thing. I just prefer to have a supply handy for when it's needed, rather than needing it (and not having it) as a result of unnecessarily using it, thus requiring a trip to the store.

The coldest I've dealt with recently was -20f and even de-icing products froze. I wouldn't even consider any water at that point. I don't know the exact conversion but I'm sure the temps are similar there.

Maybe you can put some sort of cellophane or something around the gas cap so it releases easily.

Isopropyl alcohol won't freeze in -120°F temperatures (freezing point is ~-89°C). While dilution with water will impact that, not enough that would ever cause a problem.

I just bought commercial stuff. I don't recall the brand but they sell it at the local grocery store. It would just frost right up when I tried it around my fuel door

I'm not sure what the ingredients are for what you bought.

I would dilute the mixture to be on the safe side, and if you ran into "freezing" issues (which you shouldn't), adjust the mixture accordingly. What you buy in the store can vary in isopropyl alcohol content (e.g., Walgreens sells both 91% and 70% mixtures). If you happen to experience freezing issues, either reduce the water/alcohol mixture (1/5 water, 4/5 isopropyl alcohol), or increase the initial alcohol ratio in the mixture.
