Savings are highly individual and vary significantly, with minor fluctuations always present.
Moreover, combustion processes in vehicles are complex, and each engine type is constructed differently. Even within the same engine type, manufacturing tolerances lead to variations from engine to engine.
An Example of Cost Optimization
In a survey on refueling frequency, approximately 15% of respondents reported refueling several times a week. The majority, around 36%, refuel about once a week.
This equates to roughly 300 liters of fuel per month and 3600 liters per year, assuming a tank capacity of approximately 60 liters.
By optimizing fuel consumption by 5 to 8%, cost savings of 180 to 280 liters per year can be achieved. With an average fuel price of €1.70 per liter, this translates to an annual cost reduction of approximately €300 to €470.
Adding the periodic maintenance costs, which typically arise due to soot and oil carbon build-up and are significantly reduced by fuel optimization, yields additional savings.
Example: Cleaning or Replacing the EGR Valve
“In exceptional cases, the price for an EGR valve (often including the cooler) can be up to €800. (Source: Autobild)
The costs for the replacement part are supplemented by labor hours. This is particularly frustrating when replacing the EGR valve requires dismantling half of the exhaust system, including the manifold and turbocharger, which can take up to ten hours. The total costs can then exceed €1000. If the EGR valve is more accessible, the replacement usually takes only one to three hours. Including the EGR valve, the costs range from €250 to €700.”
The costs can be up to €800.
Installing a new particulate filter costs between €1000 and €3000, depending on the model. (Source: ADAC)
Cleaning a particulate filter costs around €400 to €500.
A recent article by Focus on DPF cleaning or replacement (Source: Focus):
“Diesel particulate filters (DPFs) are prone to clogging, especially if the vehicle is mainly driven on short trips. A clogged or malfunctioning exhaust cleaning system leads to increased pollutant emissions and can cause the vehicle to fail its emissions test.”
The costs for engine damage, clogged fuel filters, or tank contamination are not included in this calculation.
The average approximate savings from innovative fuel optimization, considering fuel and maintenance costs, are around €900 to €1200 per year.
For larger engines, vehicles, ships, aircraft, generators, and machinery, the cost savings are exponentially higher.
Important Notes:
- Please protect the product from direct sunlight, artificial UV radiation, and strong electromagnetic fields. Store it below 70°C to preserve the effectiveness of the biological components.
- Always shake the bottle or canister well before use to ensure the active ingredients are properly mixed.
Why isn’t fuel savings the same for all vehicles?
a) Besides the carrier substance, which is itself a fuel, fuel optimization is purely a biological product. Biochemical reactions involving biological products always exhibit minor fluctuations.
b) Combustion processes in vehicles are complex, and each engine type is constructed differently. Even within the same engine type, manufacturing tolerances lead to variations from engine to engine.
In oil heating systems/burners, fuel savings are more consistent, ranging from about 5% to 8%.
Can savings fluctuate in the same vehicle?
Yes. Initially, one must understand that it’s a trade-off between savings and increased performance.
Many drivers unknowingly draw more performance (accelerating harder). Simply pressing the gas pedal as before results in more power on the road due to improved fuel quality but less savings. Thus, it’s either more power or savings.
It’s entirely normal for consumption to fluctuate constantly, influenced by the laws of physics, which sometimes complicates consumption monitoring.
Detailed consumption records reveal that fuel consumption varies significantly not only from trip to trip but even from one tank fill to the next.
Factors Affecting Consumption:
- Weather (humidity, air pressure, temperature)
- Wind direction (headwind has a significant impact)
- Driver’s condition (physical and mental state affects driving behavior)
- Tire pressure (varies with air pressure and temperature changes)
- Fuel quality (varies depending on the age of the fuel upon arrival at the station)
- Frequency and duration of using air conditioning, lights, rear window heater, etc.
- Other factors such as route, load, and traffic light phases
Reproducible scientific results can be obtained through PEMS measurements (portable emissions measurement systems) with consistent parameters to exclude external variables. Significant reductions in soot particles (opacity value k), CO2, and NOX can only be verified with standardized emissions testing on a dynamometer or Real Drive Test. A regular emissions test (AU) is too imprecise due to the spread of results.
For accurate assessment, measure the emissions without fuel additive and after about 2 to 3 tank fillings with the additive in your professional workshop.
Measuring pollutant emissions first without and then with fuel optimization shows the reduction in emissions. For vehicles with DPF (particulate filter), the raw emissions should be measured to provide a clear indication.
Do not rely solely on your onboard computer for consumption monitoring. Some onboard computers are accurate, while others are not.
To determine fuel consumption in liters per 100 km, divide the liters refueled (see fuel receipt) by the kilometers driven (times 100).
In urban traffic, the number of red light phases and traffic jams significantly impacts consumption.
Fuel consumption in vehicles is higher at low outdoor temperatures (winter) than in summer, especially when the engine is still cold. This should be considered when measuring consumption. Additionally, the active ingredients in fuel optimization work slower in winter, which can reduce savings and extend the cleaning phase.
Engines, tanks, intermediate lines, and injection systems are typically contaminated (with soot, deposits, bacteria, fungi, and condensation).
Fuel optimization usually takes 2 to 4 tank fillings (sometimes more) to clean the system. Often, consumption decreases only after this period.
