MANNOL 9930 Diesel Ester ADDITIVE Increases CETANE Rate Reduces Emissions Saves Fuel EXTENDS Engine Life 1 :1000 Concentration 10 ML for 10 Litre Imported from Germany (1, 100ml)

I used this in my 2015 model Elite i20 Diesel. At first I followed the instructions: 1ml to 1 ltr of diesel. I used 30 Ml to 30ltr of diesel and drove for 200+ kms. I did not find any difference. 2nd time I decided to pour in the ratio of 2ml for 1 ltr of diesel and drove for around 100+ Km. But did not find any difference. Finally I thought it's useless and instead of throwing it, I poured the entire bottle in the fuel tank and drove for 20+ Kms and I was surprised to feel the smoothness in the engine, good pickup like a new car and engine noise reduced. Really satisfying. However I have not checked the milage yet. I will order it again (250ml pack) and pour the entire bottle to full tank of diesel and then I will check the milage and update my review here.1ml Or 2ml for 1 ltr of diesel, this ratio doesn't work!

I don’t know how to measure it’s benefits

Nothing breathes life into a BS4 engine like this. The current dry diesel that is BS6 compliant is very corrosive and older engines need protection. This is THE protection.Engine quietness and smoothness.

Ok

I used it in my XUV 500.I was expecting a smoother ride and increased mileage. But, it reduced the mileage from 16km./lit. to 11 km. after 1200 km. of running. I will not recommend it for XUV 500.

For Duster 110, 4WD. The 100 ml bottle costs Rs.299. I bought the 1 litre bottle @ a discounted deal price. The liquid level can be seen unlike other brands. The ratio is 1 ml per litre. Don't keep this bottle in the car. Since I have used additives from day 1 and I am careful regarding diesel, I am not expecting miracles. Any difference in fuel economy will be added to the review later on.Dt Oct '22: Cost of 100 ml > to Rs.399. This has definitely made a difference in fuel economy.Dt Dec '24: Since the quantity is small, I mix 25 ml Mannol + 25 ml 2T oil + 50 ml diesel in a 100 ml bottle (for 25 L diesel). I tell the pump asst to pour a little diesel from top before inserting the nozzle fully.

It’s quite expensive but makes difference in vehicle performance and engine sound

First time poured 45 ml for 45 litres as per given 1:1000 ratio in my diesel manza. Gives throttle response well. Reduces engine noise certain little level only. No mileage changes.Second time poured 100 ml with 45 litres, performed better than previous ratio. Mileage 2km improved in city drive.
