HYDRA EHN-99, 2-Ethylhexyl-Nitrate 99% Pure 2 EHN Performance Enhancer Cetane Booster Diesel Treatment Additive, 1L Treats up to 1000L.

Excellent product

Works...engine sounds smoother...and I think more economy achieved as a result of using it.

Over a rolling 1000 miles my van used to average 52.2mpg. Started using EHN-99 and over the next 1000 miles I averaged 55.3mpg. Same 40 mile commuter route every day, similar speeds, weather and temperatures... vehicle runs smoother and can change up gear sooner without struggling. Only dropped a star as the dispensation method is messy and inaccurate.

Really does the job.

Keeps my MPG high and reduces the need for DPF regeneration.

I own a 16 year old 330d with 247000 miles on the clock which smoked something terrible when I accelerated, after some research I thought I would give this product a go and what a difference it had made. I still have some smoke but nothing like I had before, I would highly recommend and will be buying again. As guidance I used 200ml to 60 litres of fuel and I didn't expect to see results straight away and didn't until a week later and about 200 miles. I can't say I've noticed much of a power increase as the 330d had bags of torque anyway

Was recommended to try this by a member of the Freelanders owners club, but in all honesty, I can't tell the difference! It may be doing some good, but I can't detect it.

In the past I’ve bought other products for my old VW camper, but after reading the reviews, I decided to try this product. It’s been really good, it’s a little smoother starting and seems to run smoother too
