Joe, lots of people have said this to you but you really need to listen this time; could you please use the search function.
Since you joined the forum you have started more topics than I have in over 5 years; and all of them are questions which are answered on a weekly basis.
I appreciate it is a forum, designed for asking questions and all that jazz. But this is a daily thing, and most of your questions are being answered badly or incorrectly because the people who know the right answers just don't care for answering the same threads over and over again.
I don't mean or wish to make you feel unwelcome, and I am sorry if it reads that I am being harsh. It's for your benefit though, I just want you to be able to get the right answers for yourself.
During your ownership of your car you should be able to answer any questions you have by reading these two topics thoroughly -
