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.Regards Ken

Recommend CEM products to everyone.

The best product out there that shows clear and positive results. Easy to deal with and quick delivery. Used these in all our vehicles with great results, better performance and reduced/stopped blowby. {engine with 330,000km and no blowby}. Nothing else compares.

Very prompt delivery and appreciated the literature on all your products available included in the delivery. I have an issue with low Boost pressure and hoping your decarbonation product will alleviate this issue.
