RED LINE SI-1 Fuel System Cleaner Treatment Additive 443ml
This fuel additive is easy to use and improved the engines response, idle tickover and sound, altogether a good buy It was used on an untreated before, 7 1/2 year old 2.0 litre fuel injected petrol engine (bought new by me) just poured bottle into empty tank and filled up! great definitely worth the £15 for me.
