Yet another question! I'm sure after I've owned my Focus for a while, I will be able to answer some queries instead of asking :)
So I filled up my Focus for the first time (it had a full tank when I got it and I've now done about 500 miles). I could not seem to get the cap to go onto the filler opening in a satisfactory way - it was loose and just came off in your hand. I went home and fiddled more with it and managed to eventually get it in a position where you could not pull it off, but I don't really like it. I like a nice screw on one or one with a key to lock it in place.
Is the standard one a bit wobbly normally? I don't know if this one is standard but it has a Ford sticker on it - I don't think it is though because it's flimsy and does not match the build quality of the rest of the car!
I may buy a replacement one as there are plenty of after market ones out there - also I've heard that cars often fail their MOTs if the cap is too loose, so this is not a luxury upgrade!
Has anyone else replaced their filler cap on a Focus and which types seem to work well?
