Initially, I had doubts after watching online videos claiming that achieving fuel savings was impossible due to the laws of physics. Despite this skepticism, I felt compelled to purchase an HHO Generator from Hydrox Systems in Bulgaria. Their reputation for producing high-quality products, coupled with their straightforward answers to my inquiries, convinced me to make the purchase. I am pleased to report that my experience with the HHO Kit has been positive, particularly evident during my recent emission tests at the MOT, which yielded surprisingly perfect results.

Hello Truckers, I was motivated to reduce fuel costs for my Mercedes Actros. I purchased the HS16000, and after waiting for two weeks, it arrived fully assembled in a box. Installing it only required attaching the box to the truck, connecting wires, and one hose, which took around 2 hours. The support from Hydrox System for the Dynamic PWM of the HHO Kit was exceptional. Previously, my fuel consumption was 28 liters per 100 kilometers, but now it averages at 25 liters per 100 kilometers. This results in saving around 450-500 liters of fuel per month. I also noticed increased torque when climbing with 20-22 ton loads. Additionally, there is reduced spending on AdBlue liquid, possibly due to the HHO Gas enhancing the combustion of diesel fuel.
I suggest that all fleet businesses consider using Hydrox Systems HHO kits made in Europe for their trucks, as they offer numerous advantages. – Deiter Muller, Truck Driver and Owner
