After using the above additive I can report the following:
- Idling vibrations are noticeably lower to no longer exists
- Total running and better torque at low engine speeds
- Consumption seems to be about 0.3L / 100km have decreased, currently there are 4.9L / 100km (BC section) what else did I never managed at jetzigem driving profile. On the other hand, milder weather comes the consumption good.
Conclusion: even if the lower consumption is pure imagination is worth this additive already due to significantly improved refinement
Update September 2014
Test vehicle: Auris 1.4 D-4D, Mileage 95000km
Now other 35000km and total 4-time application of this "miracle cure" can I (purely subjective) hold:
Improve smoothness and combustion noise is beyond any doubt -
- Hoped for reduction in consumption was was also measured (0.2 0.3L / 100km at an average speed of 5.4L / 100km) while only using cheap fuel (altogether about 20,000 km.).
- Using Brand Diesel (no super-diesel) this small saving / was a hard man firmly.
Overall, the refinement with better fuel was better (several times expensive and cheap deliberately tried) so I bought last year only expensive (with 23ct / liter a difference of just 1.5 at a ~ 70 bill are, so if you like it ... ). For me, it is as far as possible to the low times of the day to buy than to refuel Billigstdiesel the better fuel.
In summary, I have to point out that the measurement / comparison is very difficult and subjective once full throttle orgy and already the consumption by the question 0.2L / 100km is falsified. Thus, everyone should form their own opinion, here it is, try making wise
A strong buy recommendation, in the worst case happens (subjectively) nothing
