#1: Petrol Cap Author: dsiingh, Location: West MidlandsPosted: Sun Nov 25, 2012 4:36 am ---- Hello all...Its that time of year again where we have petrol caps frozen. But my story is with a twist. for some time my petrol cap seems to be stuck. And im often left on the forecort of the petrol station trying to get the cap off, i do manage to get the cap off. Im quite frightened now as winter is fast approaching and i only have one key....
any ideas as to why it gets stuck and what can be done to prevent it? wd40?

#3: Re: Petrol Cap Author: macca1411, Location: Westhoughton, LancashirePosted: Sun Nov 25, 2012 5:13 am ---- Don't use WD40 in a lock. It's a water based lubricant so can cause more problems than it solves. Ideally you want to get a silicone based lubricant from a locksmiths. Wurth and Abus brands should be readily available. You can use a light oil like 3 in 1, but being oil based it traps dust which can cause clogging.
A bit of grease around the filler neck where it makes contact with the fuel cap can also help. If you can't get water between the 2 surfaces, it can't freeze.
While you're at the locksmiths, get a spare key cut. It doesn't have to be fancy with immo chip or central locking fob. Keep it in the glovebox or ashtray and use it for the fuel cap. If it does stick or snap in the lock, at least you can still drive.
Edit. This is available from Halfords or these from ECP if you don't know any locksmiths Last edited by macca1411 on Sun Nov 25, 2012 2:16 pm; edited 1 time in total

My 206 has never suffered from this issue, then again any car that is maintained correctly wont have an issue with frozen locks during the winter.

Hope you touched wood when you wrote that
Mines had all the locks lubricated, fuel cap greased up and all the hinges re-greased for the last month. The end of October is when it gets all of it's pre-winter checks, wipers replaced and spare bulbs thrown into the glove box just in case. Nothing worse than finding you have a tail light out while you're away from home. More likely to blow bulbs now as they are in use nearly every time I go out.

What lube and grease do you use please?
#7: Re: Petrol Cap Author: macca1411, Location: Westhoughton, LancashirePosted: Sun Nov 25, 2012 8:44 am ---- I have a tin of lube that a locksmith mate gave me. It has Teflon in it. It's in the shed and too cold to go and have a look at the name on it. I do know it's a green tin though. Silicone spray is a cheaper option as I am told that the Teflon spray is expensive.
I just use Comma spray grease from the local factors
#8: Re: Petrol Cap Author: dsiingh, Location: West MidlandsPosted: Sun Nov 25, 2012 1:43 pm ---- Thanks for the advice. My cap never freezes (touch wood) but its just recently im there constantly with the key twisting and turning in the luck and after abit of strugle it opens..Il try the Wurth and Abus silicone spray..
#9: Re: Petrol Cap Author: mkgin, Location: FinlandPosted: Thu Dec 02, 2021 9:07 pm ---- First winter with a 206 GTi and well... Some cheap gas and I was going to fill up but... Quite a bit of rain a few weeks ago and -10 t -15 C weather so something in the lock is frozen, key wouldn't go all the way in. I didn't want to force the key and still had 1/4 tank. So I went home.
At home I searched for the CRC lock oil... Boiled some water.
Squirt some CRC lock oil in up and down, key won't go in. Key into the hot water, wipe key, insert part way, wait. Remove, warm insert. Eventually it goes in all the way but won't turn.
I drive to a Mall with indoor parking, park and put some more lock oil in. Of course there are some streaks of lock oil running down and toward the back of the car Shop for some groceries, when I am done, it has thawed enough that it moves and can open. More CRC-lock oil.
Drive to the same gas station, get the 98E5 at the same price. Drive home, try the lock... frozen.
Before the next time I need fuel, i'll pick up a cheap emergency fuel cap, find heated parking, install the emergency cap, drive home and give the locking fuel cap a good cleaning, chance to dry out, try to figure out what part got stuck find a proper lubricant for the lock.
A few more months of winter so, a few fillups and trail and error to figure it out.

Remove the cap, turn it upside down so the barrel is facing towards the floor, then using the straw that comes with decent spray lubricants - spray a good decent penetrating oil up in to the lock barrel.
Turning the cap with the lock facing downwards should help ensure any water / condensation is drained out the inside of the barrel with the excess oil that will flow out.

Thanks!
Last night, I brought the cap in, cleaned it and used compressed air to get any water and old lube out of the lock cylinder. It had a chance to dry out next to the radiator. Then I sprayed silicone lube in the lock cylinder and on the moving parts an moved the parts and sprayed more.
I think the lock cylinder had been ok after my first try. (First time the key wouldn't go in all the way.).
I had a look at how the lock works. The cylinder turns the inner plastic part and there is a little plastic catch in the outer part that should move freely when unlocked, and locks on the slot at the end of the talk filler neck. It may have been binding or catching. After seeing it, I am glad I didn't try to force the key.
Next time around, I'll have a better look. -17 C this morning. New nordic friction (non-studded) tires underneath. They're nice and quiet, but I need to be light footed go on corners and on ramps.
#12: Re: Petrol Cap Author: clicon357, Location: KentPosted: Sun Dec 26, 2021 5:42 pm ---- SWMBO's fuel cap got so crudded up with dirt over the years I struggled one day in the petrol station to get the cap off. Ended up that the outer, coloured bit came off, I put it on the roof and forgot about it...
Got home and realised it was missing. Cleaned the locking bit with the key and the paint all round the filler with No Nonsense Degreaser. Lubed up with Lidl's spray graphite oil.
3D printed a new cap, plastic primed and sprayed blue. Not perfect but not bad for a first attempt.
