Is Lucas oil stabilizer safe to use?

I own a 2004 Honda Civic EX with 66k miles. An auto technician recommended that I start adding Lucas oil stabilizer every oil change, However, when I took it to a neighborhood oil station, one of the staff guys suggested that I don't use it. He said that this will harm the engine. Has anyone out there used this product? Is it ok to use? What is your recommendation?

waste of money IMO, my honda motor went 185k miles without it and ran like a top when i pulled it out
