Seems to work well.
The car seems to be a little smoother on acceleration since using this. It could be my imagination, but I think it's made a difference.

Seems OK
I would never know if it works well or not. I trusted my mechanic saying it will do good to the engine so I bought it (Citroen C3 1.4 petrol 2008). I must say that since I put it, the engine starts straight away and smoothly. No other signs like increased acceleration response or anything else.

Reliable, easy to use, and good value
I’ve been using this regularly for a few years now, about every three months. It’s very easy to use — just pour it in with a full tank. I notice smoother performance and slightly quieter engine noise afterwards. Not sure how well it would deal with a serious build-up on parts like the lambda sensor, but for regular use it seems to protect the system well. It gives peace of mind and keeps things running clean. Good value for money and as effective as any other product I’ve tried. I use it in a Toyota hybrid — the dealer says it doesn’t make much difference, but with the varied petrol quality around, it feels worth using regularly.

Excellent Results !!
Why did you choose this product over others?: I bought this for my aging but trusty Mercedes B class. The man reason that the engine was rough idling. I poured the hole bottle in and added £40 unleaded. After 2 days (45 miles) the problem was gone! Also I have had an engine light on for a year that my mechanic said was the fuel emission's sensor, that also vanished. Also the car seems to respond better now and starts with the feel of a new battery. So (so fingers crossed) I’m amazed ! This little bottle seems to have saved allot of cash down the garage. My mechanic suggested using this before changing filters, plugs, fuel pump, sensors etc. I’m going to use it every two months from now. Best purchase for years!!
