RE:Machines to clean engine carbonGood posts Iscaf. Just goes to show there isn't a lot of real competition out there for the Hydragen.
Just the servicing alone not counting down time for truck would be roughly $2500 CDN per year based on 100,000 miles and serrvice $250 CDN every 10000. A 10% reduction in fuel usage and savings diminishing between servicings is not very good. Also no certification or validation on efficency claims.
One thing about DYA that I have not seen by any other companies is Dynacert's process and claims are validated. Any supposed competitors I've read about is actually helping to prove that Dynacert is definitely the leader out there and has the best technology.
