Works on my old RAV4. Runs better And economy is slightly improved. Passed emissions test ok

good quality fuel additive, the engine actually smokes a little less and runs more quietly

Got my Skoda 2.0 TDI with 12k miles about 8 years ago. I've added a (generous) dose of this virtually every time I fill the tank. With 112k miles on the clock my car is still running well. Engine sounds smooth and quiet for a diesel. I don't know how much, if any mpg it's adding, or if it's actually doing any good. All I can say is that my car starts without any problem on original glow plugs, I get around 50mpg average (70+ on a long, steady run), and no EGR/DPF problems so far. Also, it feels like I'm still getting all of the claimed 150 bhp. It appears I'm on my 5th bottle of this additive, so I've spent a bit over £100. It seems to be money well spent.

very effective would use again

Improvement in mpg (actually got 40mpg on a motorway run from Manchester to York) and smoother running. Always use it when I buy supermarket diesel. RR SDV8. Slowed down the intervals between services as this was as low as 3k miles. Now upto 5k to 6k.

Mk8 transit, had surging, stuttering throttle at low speed and low revs perhaps due to dirty injectors, dropped a few mil of this in a third of a tank and within 40 miles the engine is smoother, pulls cleaner doesn't sound so much like a tractor and crucially the stuttering is all but gone. Really quite impressive value for such a small amount required.

Fast delivery, wrapped great, work fantastic 👏 👍 👌 all good

Very good product. I’m using this for number of years. Keep engine running smoothly and injectors clean from soot. Highly recommended
