I have been using this product for 15 years. One of my engines had a cylinder head gasket replaced and after 340,000 miles the cylinder head was completely clean. Fuel consumption improvement is over 5%, engine performance is sharp and smooth, but most importantly my 16 year old Citroen gives lower emission readings than most brand new diesels and it now has 170,000 miles on the clock. The EGR valve has never had to be cleaned or serviced. This product saves more money than it costs.

I answered 'yes' to 'recommend?', 'good value?', 'good quality?' questions but, 'Does it do what it says on the can (sorry, bottle)?' In all honesty, nobody knows! You simply can't do an A and B test. If the claimed benefits are true, it may well be helping to prevent my particulate filter from clogging up too often. No measurable increase in economy, though. One bottle lasts several tankfuls, so it's not too much of an extra cost. And it's a clever bottle, making it easy to give the right dose of medicine to your motor.

I've been using this brand of injector cleaner for a few years now. I used to buy it from Halfords or similar shops but then realised I could get it cheaper on Ebay. One bottle will last for six or seven full 50 litre tanks of diesel and is better value for money than the products where you use the entire bottle in one tank. The product also increases the cetane rating of the diesel (similar to what octane does for petrol) giving you a bit more power. Use this every tank full (or every other tank full it's up to you) and your vehicle will run like a sewing machine. I've driven diesels for twenty-odd years now and was advised by an old diesel fitter back then to use injector cleaner regularly. It makes sense and prolongs the life of your injectors without a doubt.

Good: Works for me better than Super Diesel, more mpg and more "go", and works out cheaper than the 12p/ltr premium I have to pay for Super Diesel. Don't know if it is more eco-friendly, but if it aids efficiency then I would guess that it makes for more complete combustion. Not So Good: getting the precise volume to add isn't always easy especially reducing the volume if you manage to get more than you need in the reservoir.
