Trig Posted May 14, 2005 Share Posted May 14, 2005 Are they any good, the STP/Slick 50/ecotek fuel additives that are supposed to clean out your fuel system. If they do work, which is the best? and are the octane boosters any good? Link to comment Share on other sites More sharing options...
Timmy C Posted May 14, 2005 Share Posted May 14, 2005 If you dont already use optimax / super unleaded, just use one of those rather than addatives to normal fuel as they clean out your engine after about 2000 miles Link to comment Share on other sites More sharing options...
Placid Escort Posted May 15, 2005 Share Posted May 15, 2005 I have used "STP complete full system cleaner" and noticed a big difference. Car runs much better and more responsive. Added Slick50 gearbox treatment to my gear box and noticed that was alot better too. Link to comment Share on other sites More sharing options...
