HYDRA EHN-99, 2-Ethylhexyl-Nitrate 99% Pure 2 EHN Performance Enhancer Cetane Booster Diesel Treatment Additive 2x 1L Treats up to 2000L

Excellent stuff after filling tank and adding this to my diesel tank after 2days of use it's gained more MPG with n more black smoke from exhaust when I put foot down absolutely recommend using this if you have a diesel vehicle I will continue to use this

Used to enhance standard Diesel and allows it to burn more effectively.Too soon to tell but be careful not to spill on hands or clothes or in car- THE SMELL DOES NOT DISSIPATE QUICKLY- WEAR DISPOSABLE GLOVES!!!!!

Cetane levels in diesel in the UK are low. I took the plunge and bought some of this product. I have a thirsty 2.5litre 4x4 and tow a twin axle caravan. The only painful thing has been watching the fuel gauge move downwards quickly! After adding the recommended amount of this product to my fuel tank - my mpg has increased from 23mpg to 27mpg. The proof is in the pudding & l am pleased l purchased this cetane booster. With the increase of 4mpg - this improvement clearly offsets the costs of this product. Just be careful you don't overdo the amount you add to a tank otherwise this will not be cost effective.

Good quality easy to use good results Always take extra care when working underneath high voltage power lines.

This has improved the running of my VW a lot

Delivered earlier than expected 👍 have dosed both bio 1:500 and pump fuel 1:1000 definitely smoother power delivery and returning around 3-4 MPG better than before

Great product

Excellent Service and price.
