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

This has improved the running of my VW a lot

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

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

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.

Liquid hard to get out buy a pipette

Been using 2-ehn for years. Works well for me regarding extra power boost. Price of it seems to have a power boost too from ALL suppliers.

would have provided more stars had the item actually bren delivered with 1 litre of the product!!!I thought when opening it it looked low so I measured it on very accurate scales and the total weight including all the packaging was 1008 gramms!!!1000 gramms per litre of liquid and the small plastics filler nozzle weighed in at 13 gramms so the actual product was at even the higher estimate only around 930 mls of product!!Very annoying when you have paid for a litre yet been provided with less than this.I have ran several tanks and my mpgs have actually gone down even though I never change either my driving style nor route.This is worrying as now the rev gauge has started to fluctuate and that was after the second tank with this product.I chose a more expensive brand and up my mpgs went as well as stopping the rev fluctuations.I will most definetly not be using or recommending this product as it was a complete fail!!!

Ok
