Why do you use it? Are you having a problem with your car?
You should read the car's manual to see what it may say, and then read the instructions on the can.
I use one bottle of additive around November to prevent problems if it gets cold early, although I have never had a problem that could have been eliminated or reduced by any additive I know of. I have no idea if it does any good, but it doesn't hurt it.
That being said, I've heard of people using it anywhere from once a year to once an oil change.
