petrol filler cap

this may sound silly but has anyone had there's do this .I fill up then fasten filler cap maybe two -three click's .if I check it say day after it has started to undo its self !!!!!

 

Ha! Thought it was just me! I always check and re-tighten day after filling. Although if you push against the cap while it clicks seems to tighten a bit better!

 

thanks for that give it a try tomorrow

 

Nope, never noticed

 

I don't think it come undone just turns when clicked on, nothing to worry about.

 

yep ,, i allways turn it till i hear the clicks !
