Absolutely works a treat would highly recommend for those who do short journeys

The measurement of this product is very subjective. The question is mainly how does it feel? I used it for preventative purposes rather than to cure a problem.So far however the performance does seem better. Time will tell

MPG did slightly increase, had a engine management light for egr valve open, didn’t clear that, egr still needed to be stripped down and manually cleaned, maybe use from early on could prevent carbon build up, but will continue to use as it did seem to increase MPG

Used this on my old diesel Jag. I was having trouble with the emissions test in the MOT.. Used as directed prior to the MOT the emissions dropped by almost 50 percent to 1.98 from a previous year result of just under 4 (over 4 is a fail) Also cured the black smoke problem when you accelerate hard on these older engines. I thoroughly recommend this product.

Good value

Not had any issues since using it.

We have a bmw 2015 535d, which with most diesel engine vehicles of this age are prone to Dpf issues. Every 6 months or so, in addition to the odd blast up the motorway, I put this treatment through the fuel tank. All I can say is, to date, it has prevented any Dpf issues on this vehicle & previous cars, long may it continue!

Used per manufacturer instructions but can’t say I noticed any difference, perhaps it’s just me or car.
