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!

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.

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

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.

while many people are promoting this product.. I used this product but got dissappointed.. After 1500km there was no increment in power, no smoothness as flaunted by brand, instead i dropped my mileage about 4 to 5kmpl... Now waiting to finish this bottle and i will stick of diesel only... My car was Nexon BS4

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
