  • Any reviews from fellow Ozbargainers? SCA website reviews look promising though.

      I haven’t used that specific one, but have used liquid moly engine cleaner and diesel injector cleaner with very good results. I was very impressed with the engine oil cleaner and highly recommend. In fact all liquid moly products I have used have been really good…

      Now whether your fuel systems needs to be cleaned is another question. That said, for the price it certainly won’t hurt and could save issues with your injectors down the track so I’d give it a go.

      • Cheers!

      • Same here. Used engine cleaner and it cleared up a warning light on my Audi.

    • My previous mechanic used this on my car every service.
      I think they had a deal with LiquiMoly though.

    I've used this.
    No noticeable improvement or difference.

    This was one direct injection gasoline engine though.
    I ended up pulling the injectors out afterwards. They were filthy and nothing but mechanical (physical) cleaning could solve.

  • The pic on the bottle shows cleaning effect on port injection engine, and ingredients does not contain polyether amine (PEA). So might not work well on intake valves of direct injection engine. Although I'm happy to be proven wrong.

      Well it can't clean valves on direct injection because valves are before injectors.

      Having manually cleaned intake valves before, it requires a lot of mechanical scrubbing not just a chemical spray.

      • Don't need mechanical scrubbing. Walnut blasting is the method of choice in most cases. Might save you some pain next time around. The purpose of this product is more so to maintain a clean intake.

  • This is a waste of money in my opinion, better off adding a tank of premium and hit the Reds to give everything a nice clean
