HYDRA MAXIMUS fuel injector cleaner, 1 Litre treats Up To 500 L, for cleaning diesel injectors performance enhancing diesel turbo cleaner additive for diesel fuel EGR valve cleaner diesel engines

I run a 6 year old Renault with the 1.6dci and on the whole it’s a great engine. Since buying the car 6 months ago I’ve changed all the fluids and filters and the car runs perfectly, however I’ve always felt that it was very flat lower in the rev range. Like others I’ve previously used Millers additives in my Diesel cars and can’t say I ever felt much difference so this time I decided to try Hydra’s product - what a difference!! Since adding this at the recommended dosage the car feels noticeably stronger at lower rpm and my mpg has increased by 3mpg on average. I’m now able to drive in higher gears without the engine feeling like it’s labouring all the time and the pickup in any gear feels much better. My engine was always quiet and smooth enough for a diesel, I’d say it’s running a tiny bit quieter and smoother but given my car wasn’t running badly anyway it’s hard to be sure as the difference is so slight - certainly it’s had no negative effect on this at all. Totally agree with the other reviewers, for the price give it a go - it’s not a lot to loose if it doesn’t work for you, but going by my experience a whole lot to gain when it does! I’ll certainly be buying more Maximus going forward. Well done Hydra this is a great product.

This additive definitely does something to the car, there is a fuel saving, but not huge, the big thing for me is the result it has on the engine, with the additive the engine is so much quieter and a lot smoother. Running a 110000 diesel Vauxhall so like to look after the engine. I have been using this company's additives for over a year now and rate these over the big name brands 100%

I don’t usually do reviews, I have a 10 year old Mercedes c250d which is new to me I have heard that running premium fuel is best for these engines, now the car was running fine but I thought I would try this to see if it made a difference, I do a lot of long motorway long drives have used this in the last 3 full tanks of fuel and have noticed 3/5 better mpg maybe this will improve overtime with constant use as I said car was running fine but I have noticed smoother acceleration and maybe a little more power I will continue to use for a while and see if I get any more gains if I do I think I will continue to use

Good

Brilliant stuff. Actually does make a difference, after a couple of tanks with this in the engine sounds a lot smoother and feels like it picks up marginally better, it's also much cheaper than buying premium fuel. I've tried many different fuel additives, liqui moly, wynns, stp and a couple of others but this is by far the best.

I was very sceptical about this product and the claims it makes I’ve been using it now for about 2 months and my van a 2014 vw crafter has got improved performance the acceleration is massively better and I am getting about 50 - 60 miles to the tank more than before The product does have a strong smell to it when your putting it in but not when you drive I would definitely recommend this and will be buying more

Used on a 2007 2.2 Honda Civic i-CTDi. The car always ran pretty smooth due to years of filling up on Shell V-Power diesel. Put this product in with normal diesel and the difference was immediately noticeable. Works out cheaper to buy this and add it to normal diesel than buying premium diesel. Been using this product a few months now after every fill up. Car is more responsive when setting off. Lower revs gives more torque now. BHP has increased when tested. City driving MPG has also gone up by around 8 MPG. The bottle is an awful design and can easily leak. You don't want to keep this product in your home or car though as it is very smelly! The only thing this product DIDN'T do as claimed is clean the EGR Valve. Which was just as filthy as before I started using Maxiumus. Maybe you have to use it for a long long time before it would have any effect on EGR. I will continue to use as it is the best fuel additive I've ever used.

Good product with its handy dosing bottle attached. Can be a bit messy to get into petrol cap though. Delivery was quick and a lot of shots for the money

È un ottimo prodotto e posso garantire che già dopo i primi 100 km si vede la differenza,migliore risposta di coppia, motore più fluido anche ai bassi regimi. Continuerò ad usarlo. Sul prezzo purtroppo è vero è un po altino ma sono soldi spesi bene per far vivere più a lungo il motore e le sue parti. Mi sono accorto in più che ho consumato meno additivo Adblue a parità di km e tragitti fatti quindi il prodotto funziona per me. Sui consumi dipende da come la si porta l autovettura cmq un minimo c è di riduzione ma capite bene che le prestazioni saranno superiori a parità di motore.

Experimentiere seit Jahren mit verschiedenen Produkten. Maximus hat mich beeindruckt. Meine Mixtur ist 1:1000 Zu Beginn etwas höher dosiert. Wir verwenden es bei einem BMW 320d Mercedes Sprinter 316cdi und einen Ford Transporter Fazit: Der Motor geht schneller auf Drehzahl, der Turbo beginnt früher Leistung aufzubauen. Besserer Kaltstart und ruhiger Motorlauf. Wir haben ca.0,4 Liter weniger Spritverbrauch als vorher. Ist bei uns im Dauereinsatz, saubere Verbrennung,gute Abgaswerte. Bin sehr zufrieden.

Después de usar todo el contenido no he apreciado una disminución el el consumo de gasoil. Sí he notado una mejora de suavidad en el motor. Por otro lado una vez abierto desprende un olor bastante fuerte, y dado que lo llevo en el maletero cada vez que abro el maletero el olor es molesto.

Lo estoy usando, esperaré a comprobar que tal va. Aparente mente va bien

Veramente ottimo
