Review: Resolved a rough-running Fiesta Zetec 1.25 engine - T’ wife’s 2012 Fiesta Zetec 1.25 was running really roughly. Hunting at idle, sluggish acceleration, woeful mpg. I used the combination of Liqui Moly 4066 maf sensor cleaner and Liqui Moly 1803 injector cleaner, which did a great job of sorting out the problems. Result is much smoother idle, more power and 40+ mpg instead of 25 mpg. It may not work for everyone, but it worked well for me.
Review: No noticeable difference... - I've added this Liqui Moly 4066 bundle, with 1803 Injection Cleaner into my petrol tank, and sprayed it into the air intake. But my Mercedes A180, which is basically a computer on wheels, cannot detect any improvement in either engine performance or fuel consumption costs. So it would appear to be a waste of my money, which I could have spent on buying some more petrol, which definitely would have improved my fuel consumption costs. I'm disappointed in myself for believing the sales talk. Not recommended.
