Went to book second oil change and the dealer told me that along with the brake fluid, oil and all sorts of filters I need to change the spark plugs. Thats what the computer indicated. He even showed me the printout but was pretty clueless as to why this is coming up. This seems really odd as my car only has 22 000 kms on it and it is under two years old. On all my previous cars the spark plug change has been after 50-60k. Any ideas...
