A spa weekend for your injectors.
Genuinely cannot believe how effective this product really is. I thought my Supercharged V8 was in tip top shape until I poured a bottle of this in the tank. It no longer has an intermittent misfire at high RPM, it is even smoother than it was before. The engine sounds showroom fresh. The car is much more economical, pulls harder under harsh acceleration and is considerably smoother on both idle and pull away. Overall I would say not only does this product live up to every claim it offers exceptional value for money, as you only need one can every 2000 miles and the results are delivered very quickly.

Brought for my borther
I read the reviews and bought for my brother who was struggling to get his car working. This worked an absolute treat it was recommended to me by another family member, don't let the low price put you off this is Brilliant and great value for money, it's easy to use and works really well cleaning the injectors, no leaking from the can so no product wasted. If you're needing something like this don't wait just buy! It does exactly what it says it will.

I don't know if it helped or not
My Z4 has had a load of issues with not running quite right so I thought I'd try some of this after being told the actual liquid I wanted I couldn't have, I put the lot in on a 3/4 full tank of fuel and I can't say I've noticed anything. I'm giving if 5 stars because I don't think I should mark it down at all just because I can't feel any difference to my cars running. Give it go, if this is the right liquid for your problem.
