So my car has been starting a little rougher than usual and since I had a smog test at a star station coming up (I live in CA) I decided to do a tune up, well to my surprise when I pulled the plugs they all looked like they had rust on the tips aren't plugs suppose to normally have a whitish coloration after being used for awhile, these plugs are about a year old I would say, anyone know what can cause them to look like this

Some fuel additives can cause the plugs to turn brown, but it'll be almost crusty in appearance. Normal use makes them tan. Running lean they'd still be white, running rich they'd be black from carbon deposits.

The car is also designed to run on regular fuel, so anything over is a waste of money.

Actually, getting paid to take something would be.
