## Customer Reviews

### ⭐⭐⭐⭐⭐ Works for me.
*by K***K on 14 August 2025*

Does what it says on it. Product not not pricey as well.

### ⭐⭐⭐⭐⭐ Great stuff for UK cars / vans
*by A***W on 12 March 2024*

I’ve been using this stuff on multiple vehicles for a while now, on higher mileage stuff I’ve been mixing it with a small amount of 2 stroke mineral oil as well.If you use premium fuel regularly, this may not be of any use, but if you often fill up like me at the cheapest / nearest station, a small amount of ehn 99 imo improves fuel economy, engine running in general, cold starts, limits diesel smoke and just an overall appears to give a better running, smoother cleaner vehicle. More so if you have high mileage or older diesels like me.Also, beware of your friends stealing some from you.

### ⭐⭐⭐⭐ Subjective easier start ups and less clatter
*by M***H on 13 December 2023*

I mixed the first drive 50ml to 25l of fuel and the second 50ml ton50l.It's difficult to judge if this improves mpg because going into winter diesel is subject to winterised fuel which reduces mpg anyway but I think my mpg is roughly that of summer fuel so maybe a very slight improvement over standard supermarket fuel.Subjectively, it appears to ease cold starts and would appear to reduce some of the clatter associated with my diesel engine.I haven't noticed an ill effects.Make sure you wear gloves when you use this as it stinks and is hard to wash off the smell of you get it on you.
