Game changer

Ok so what would bring you to buy a product like this, maybe you've tried other brands and you didn't notice any difference, ive been there too!

This Diesel eco max by Millers is different - i started using this back in 2014 in the winter my A4 TDI ( AVF engine 1.9 ) struggled to start and at 1st i thought 🔋 so changed that - no improvement - 2nd changed the glow plugs - no difference - scratching my head i did some research and found super market fuel is a bit hit and miss on quality so options were to buy fuel from more expensive stations i.e. BP Texaco or try an additive - that led me into a minefield of possibilities - i wanted something that is long lasting and proven to work - i came across this millers additive and found 100's of positive reviews - thats it! Lets give it a go - within 2/3 days i had no start issues whatsoever and needless to say i have been using this ever since - i never have any problems starting the engine rain cold or shine 6 years on and that was 52k im now at 130k - the engine runs better - improves mpg and the best bit i can still fill up at supermarket stations saving even more money - so with the millers bottle you can add 25ml or 50ml so half / full tank with a squeeze of the bottle and will treat up to 500 litres per bottle - great value and peace of mind - also millers are a UK company based in Yorkshire so helps UK jobs win win!Read full review

Good product, poor maufacture.

I have had very good results using this additive. One of the bottles has a tiny leak at a seam and some of the contents contaminated the parcel upon delivery. This is highly pungent and the odour is persistent.Read full review

First class product

Does what it says on the bottle, engine quieter,smoother more power and improved mpg. This works on new cars and very old cars and transit vans. Look its not magic and will not transform a sick engine but you will definitely notice a difference when you are using it. I have been using millers for the last six or seven years in 5 different cars without a problem..Read full review

Good product. The more I use it the better it is. Keep the mpg down and the engine nice and clean. Really notice the difference if I miss adding it.

It works. But only when used with regular diesel, there is little or no improvement when used with premium diesel.

Have used this product for years, and car sails through mot emissions. sMost of my local taxi drivers use it so I m told.

Millers oil diesel additive

I have been using this product for about 6 years in my 51 reg Astra van, and every time it goes for the mot the tester asks the same question why are the emissions so low??
I also noticed an increase in power and a decrease in fuel consumption, I Also use it in my freelander
I will never use anything else!!
Great product

It works

Used this stuff for years in my Diesel engines, gives both mpg improvement (5 to 10 percent), and less smoke from the exhaust. More than pays for itself at a cost of around 2p per litre treated, especially when filling up with cheap supermarket fuel that lacks the additives/lubricants found in the premium diesels from Shell etc.Read full review

Millers diesel additive

I find it keeps my diesel engine running clean and quiet. I have used it since I bought the car 3 years ago, and milage is now 133,500 and still running nicely, and with good mpg figures.
