## Description

From the manufacturer

Review: 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.
Review: 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.

## Questions & Answers

**Q: Is this ok for diesel engines**
A: I think this one is for Gasoline only, check I’m sure they do a similar product for a Diesel engine.

**Q: Can this product be used with E10 fuel.**
A: I would think it is suitable. But I have switched to using super unleaded, because it has extra additives and more efficient. E10 is bad idea, because it attacks plastics and rubbers, especially on older vehicles including garden machinery.

**Q: Is this for petrol engines? N16 Nissan Almera 1.5 petrol manual.**
A: Hi there. It is for all petrol injection engines.

**Q: Is this sutable for my petrol clio?**
A: yea its suitable but somehow rpm goes up right after using it... you should get Lucas Oil 10020 Fuel Treatment. its far better for petrol engines for regular use. optimizes power and driving feel gets better.
