Funny, I actually was trying to figure how to add a bottle of royal purple fuel injector cleaner yesterday.

There are two safety buttons/taps that need to be pressed down before the metal cover will open. My funnel would only let me press on one button, so I used a small flat head screw driver to press the other and it finally let the funnel through.

But I didn't know there was a funnel in the trunk, I'll have to check mine where the spare is.
