My name is Thomas Hinderer. I drive a 1992 Mazda 323 (1.3i) (for nostalgic reasons). Because of my job, I have to drive around 60,000 km on the motorway every year. I am a development engineer at a southern German car manufacturer. Because of this, I am always interested in consumption-reducing measures. When I read about your innovation in the newspaper, I probably felt the same as many other drivers. How is a small metal stick that you hang in the tank supposed to have a positive effect on the consumption of an engine? With the knowledge of my Technical College education as well as with the knowledge of my mechanical engineering studies, this was absolutely incomprehensible. Nevertheless, my curiosity was greater than my reason and I bought one of your pens. What I noticed immediately after driving a few kilometers in stop-and-go mode was that the engine ran much more smoothly at low speeds (approx. 1000-2000 rpm). After about 20 kilometers, a significant increase in torque when driving off from a standstill was noticeable. Because I often commute between Vienna and Munich by car for work-related reasons, fuel consumption was of course a very important parameter for me.
That's why I always drove at exactly 140 km/h (according to the navigation device) on my freeway test drives. Furthermore, I also paid attention to the same ambient temperatures in order to make a measurement that was as realistic as possible. What was amazing for me was the steadily declining consumption of the engine from initially 10.1 liters/100km to 6.9 liters/100km. Furthermore, I'm already curious about the next check of the exhaust gas values, which should also be lower. I will submit these as soon as I have them.
My conclusion: I absolutely could not imagine why a stick in the tank should have such an effect. I was teached a lesson. As can be seen in the graph, consumption fell from 10.1 liters to 6.9 liters at a constant speed of 140 km/h. Since I know from my job in engine development how much effort is required to achieve a 0.5% reduction, this product is an absolutely sensible innovation, especially for the end user, but also against the background of fuel becoming more and more expensive, which you can continue to use without hesitation can recommend.
When measuring the exhaust gas, the CO value was reduced from 0.18 vol% to 0 vol% at increased engine speed!
