same here. as you turn the key, you should be pressing down on the cap. when you close it, push down and turn the key at the same time as well. this method should work, short of having lock corrosion, or otherwise boogered up lock.I find it's difficult to open unless you really push down on the cap while twisting key
i have a 2008 with original cap as well.I had this problem and have used WD40 to no relieve to the problem until I fill tank top every time so the fuel lubricates the lock mechanism . its been 9 years and I still use the same original key and tank lock without any problem.
( i know petrol is not a lubricant but somehow that's the best advise i got from local mechanics and its works fine)
I'd try some dry graphite lube in the key slot first and open close the cap numerous times to work the graphite in completely....if that fails to do the trick, then I'd run some WD-40 into the slot. If that still doesn't smooth it out, then I'd be thinking there is some mechanical imperfection in the cap or lock mechanism itself.I do press down when turning, but the turn itself is very tight and gritty.
This is the first I've heard of this, but evidently internet true...You'll get "dissimilar metals" corrosion.
WD40 works PDG for ME....
Lol, yeah. I get all that. I meant for their claims on the website.Corrosion:- is nothing but it is a chemical reaction (most likely a oxidation process) in which wearing of metal takes place . Here the metal can be anything iron, copper etc . Rusting :-This is a part of corrosion in which Iron reacts with water or moist air to form iron oxides and thereby corrosion takes place .
I should ask - would the gas tank then be unlocked and accessible by someone else? I'd like to know that anything entering the gas tank was put there by me, and not someone/something else, intentionally, accidentally, or by natural causes.I am hijacking an old thread, but it is gas cap question. My latest vehicle a 2014 Ford Edge (not too high tech) has the fuel filler where I just open the fuel door and push the nozzle in the little silver flap. No fuel cap at all. And the fuel door is not sealed in any way. Has anybody ever seen a fuel filler for the V that is like that - just press the fuel nozzle in and fill??
