CRD fuel enhancer
I have been using CRD fuel enhancer for about four years now and I give it a 5 out of 5.
I purchased 3 products recently
I purchased 3 products recently. The Clean power improved fuel economy on a recent 2,000km trip I just did (down to 6.6Ltrs per 100 KM) 2011 2.0Ltr diesel Kia Sportage. I used the FTC Decarbonizer to help with DPF cleaning but as it has not been faulty as yet I can't say if it's worked. I plan to put it in an old 3 cylinder Lister powered dump truck to stop excessive smoking along with the Flushing Oil Concentrate at next oil change. Will let you know results when done.

Good products
Easy to order online and have delivered to home in just a few days. No hassle's.
Noticed improvements
I have noticed a increase in response when needing power since using the Decarbonizer. My fuel consumption has also improved (decrease in L/100kms) according to the computer. That's a win. Still needing more time to run the Decarbonizer and hoping it helps resolve my DPF issues I have once it's given a good ol clean out.
