Diesel Power 7 Complete Action Fuel Additive Optimises Engine Performance 1L

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.

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.

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.

Exactly what was ordered

Good quality, fast delivery

I bought this product because someone mentioned that thanks to this product the Christmas light panel in the car disappeared. We were having a bit of a laugh with my son who works with cars. We made a bet, he said the engine light will remain. I said if this product clears the engine light I will pay you a dinner. Nobody won the bet. However, my son said the product is good and internationally cleans a lot and recommended it for old diesel cars like mine every 10000 miles. It seems it runs smoothly but we also did some other things in the car. I will repurchase it. Perhaps you can compare with an old person taking supplement vitamins. To keep healthy the car inside is essential in the long run. For example, this can make the difference of changing the car today or in 5 years. Last review Jan 2025 The car has driven another few thousand miles, and the weather, as you know, in Manchester is terrible (-6 this morning). Honestly, I feel that the car runs better than before. So, perhaps I am lucky! No extra work has been done so far in the car. The light remains there, but this is due to the glow plug. His heat is terrific, and there is no problem whatsoever. I will buy another bottle if I do another 7 thousand miles and the car gives me no issues.

Item arrived without the nozzle attachment as pictured in the photos and description, so was a pain to put into the fuel tank. Will update review of the product in a couple of weeks to see if it actually works.

Used it on my 2009 Octavia with 126000 miles, never used it before and it’s well worth to try. What can I say about the diesel power 7! The engine runs and accelerates seems better and my fuel consumption seems to be lower but not massively depend on how you drive! The turbo doesn’t feel excessively lagging as it used to be or any odd occasion flat spots down the rev range! Truly well worth a clean out and the value of the money! Definitely will be using it again every now and again! Fantastic!

Très heureux de ce produit ! En effet, je l'ai utilisé peu de temps avant le contrôle technique de mon véhicule et la pollution était nickel ! Je recommande ce produit.

Comme mon véhicule est diesel et que malgré un entretient soutenu ,le contrôle technique pose toujours un problème j'espère que mon passage sous peu , se passera sans souci

Très bonne qualité

Excellent product, but Amazon shipping not so much.
