Review: Excellent in high milage VW TDI - Used in my 2.0 tdi Seat Alhambra with 159,000 miles. Made a massive, noticeable difference. About 3 - 5% better economy and better acceleration. Noticed improvements after about 1/2 tank.
Review: Cured my cars minor sluggishness - I've had my car for 2 and a bit years, it's a moderately old car, 11 years and counting. I've occasionally put some diesel redex in, just the cheap stuff, but I felt it becoming more sluggish recently, no warning lights or anything, just a subtle sluggishness that made me doubt if there was anything wrong at all. Put this in and ran the tank over about a week, and even halfway through, I could tell it was a night and day difference. +8 MPG on average (50 +-2 up to 58 +-2), I have also discovered a mountain of low-end torque that I just never knew I had, which was a delightful surprise. If anything I would assume that my injectors were a bit dirty and this cleaned them out, but I'm no mechanic. I wouldn't say it was smoother or quieter, but again, I don't think my engine was really in that bad a state to start with, unlike most people who buy this product. I will more than likely add a tin of this to my yearly service to keep on top of everything. Highly recommend for just keeping your car running well, or if you notice it being slightly underperforming, instead of just waiting until it runs like rubbish or you get warning lights.

### ⭐⭐⭐⭐⭐ It really does work wonders!
*by J***N on 10 June 2025*

Having seen other positive reviews I decided to give this a go when it was on sale. I was not disappointed! I emptied the contents into my empty fuel tank and then filled up with regular diesel. I did not really notice much at first but then after a short drive I did notice that on acceleration it was blowing a lot of black smoke out of the exhaust. This soon stopped and the car started to feel a little smoother and more responsive. Over the next 150 miles or so the improvements continued and the engine became quieter and smoother and it seemed to be more pokey like it was when I first bought it. I have now just refuelled and the car continues to perform better than it has in a long time - quieter, smoother, more responsive, more torque and better mpg. I am truly impressed with this stuff and would recommend it to anyone. My car was a 2018 Jaguar XF Sportbrake with around 85k miles. It's the 2l 180bhp version and it really did make a difference to the engine which continues now. If you have a diesel with high miles I highly recommend this to give your engine some tlc.
