Great product I have used it for a few years, I use to buy it from Halfords in a litre bottle but it is now the price has gone up, so that is why I buy it 5 litre container it is much cheaper, I get more M.P.G and my engine emissions is great thanks

Since I have started using it my engine seems so much quieter and fuel consumption appears to be slightly better,of course it will take some time to get a true reflection of its use ,but at the moment I am satisfied with the product.
