Guys, been talking to a friend of mine who uses redex on his car quite regularly. Anyone had any experience of using it? Any efficiency, performance improvements seen?
don't do it.. really.
sure, you may see initial benefits, but decoking an engine is often not a good idea - especially if it's an old(ish) engine (say, 7-10 years....)
Be aware that some garages can make a lot of profit on fuel additives they may try to persuade you it's a good thing. I had a service receptionist tell me it was all about how injectors squirt and spray!
