Fuel Injection Cleaners

Any recommendations for a SL1?

Id hate to get something that would do no good or worse yet...do harm to the system.

I've used STP fuel cleaners and octane boost on my 97 SL2, no problems for me.

I have a 94 SL1. I have used most brands, STP, Penzoil, Amoco. They all seem to cause no problem, and routine use has done me better than the expensive cleanouts I used to get at the dealer. Some months ago the Penzoil oil change place talked me into adding Slick50. They recommend it to all cars that eat a lot of oil, which means older Saturns. I decided to go for it. My engine ran noticeably nicer.
