“Over 500 mile journeys repeated regularly I have found maybe a 5% increase in economy. Main benefit for me was smoother quieter running of a VW Diesel engine. My Mercedes diesel runs beautifully quiet with this additive. Don’t use continuously but I believe periodically is a of benefit to your engine / fuel system”
“This product was highly recommend by a mechanic friend of ours who has used it for years and swears by it. We have only just started to use it so fingers crossed it will prove to be a winner”
“Have used this product for many years - pays for itself in improved fuel economy. Also engine reliability is enchanced in terms of fuel injector health.
The redesigned bottle with the long neck makes getting the additive into the filler cap so much easier on my car (Ford Focus with anti syphon flap).”
