- MANNOL 9955 (450ML) CETANE Plus Diesel Fuel ADDITIVE –Boosts cetane Number&Cleans Fuel System for All Diesel Engines Imported from Germany (450ML) (1)

I have Renault Duster diesel engine 85ps 2012 model I have use Mannol 9955 Cetane plus in my diesel car. Really it's working, the fule is refine and the performance become smooth. I really recommended this product 👌

Excellent product improved acceleration, mileage and engine smoothness.

Better performance and smooth drive

Improve performance ,

Used it regularly for last 4 months yes there is a noticeable uptick in FE for the Pajerosport. 3stars only because it's so not practical to use the bottle it's coming from 1. It doesn't shut properly after use. ( Instructions on how to open is given, but how to shut the cap over the safety lock is not mentioned or not possible to attain) It leaks in the vehicle leaving a strong odour in the vehicle , impossible to ignore and it gives a dizziness after inhaling the vapour. 2. No measurement feature. When the bottle says a recommended dosage to follow, a simple option to follow that also should exist!! The tip of the bottle is so rounded, it flows everywhere..!! So after painfully finishing 2 bottles , going back to Iftex system D which I'm using for last 4 years. Yes it worked better than the sys-D in terms of FE. Dong know how easy it's on engine. Since the cetane addition makes the fuel slightly more dry is what I could understand, though the package says it's improved lubrication of fuel . Will be going back to 9955 only once it gets the packaging corrected

Not effective in BS6 Diesel engine, I used it twice and on both occasions the dashboard gave engine check light error.

Received opened bottle without the standard protective seal. Doubtful of the contents and authenticity of the product. Stay away from Seller German Auto Parts!

Didn't make much difference in Volkswagen Ameo TDI

I’m very happy & will buy again

Brilliant product gave me the extra power and mpg i required for a good price seller was very helpful would recommend for all diesel engines

Incredible stuff ! Took a while to deliver as from Germany but well worth the wait.Using in a Peugeot 407 1.6hdi with 85000 miles clocked.Introduced half of one of the bottles to approx 50 litres premium/standard diesel in tank,and the difference was immediate..computer trip consistently 62 mpg up from previous 55,very smooth idling,no hesitation pulling away or in any gear(previously was a tendency to hesitate in 3rd/4th gear,use of 5th gear would bring on DPF regeneration,had that problem for 4 years....within 4 miles of this stuff going in all of that hesitancy stopped.The car is more responsive too.Will be definitely be re-ordering this additive,it beats anything I've used over many years.(This review submitted after 1070 miles.)

I don't feel any difference after filling up my car. After filling up with WPower fuel at Shell, I felt a real difference.

Improved fuel economy. Before 49.3 mpg , after 2 70L diesel tanks, half the bottle each tank I get 50.5 mpg
