I have now almost 10,000 km down my FK3 and until now always “normal” diesel fueled. Last time I drove the tank almost to the last drop empty and then once BP Ultimate Diesel fueled. Admittedly, the stuff is sultry expensive (with us in Austria more expensive than the most expensive gasoline), but I was curious and wanted to make the test on the example. How much does it actually bring to the Civic FK3? Well, despite all the unkennrufs I notice a difference. – The verbr Also: The BC showed me a consumption of 5.9 liters at the last filling with normal diesel. With BP Ultimate Diesel I stand with guaranteed unchanged driving mode (which I take care of exactly) at 5.7 liters according to BC, i.e. a reduction of 0.2 liters per 100 km. – Noise development: I can’t judge whether the engine has actually become quieter in idle mode by BP Ultimate Diesel. At the most in an area that is only perceptible if you have ears like a lynx, what happens to me. It is not the case. Nevertheless, the engine runs as usual calmly. – Acceleration: A surprise! When accelerating, I often had a core accompaniment sound with normal diesel. With BP Ultimate Diesel it is now the case that the core sound becomes quieter, whereby the turbo noise comes to the fore – less nailing, but louder turbo noise. Whether the acceleration itself has become better, I cannot judge – I have not stopped yet or the like. Subj From an active point of view it doesn’t go better, but also not slower – only the acceleration itself is now more pleasant for the ears, because the engine itself has become quieter (as I said when accelerating). I probably lead it back to the high Cetan number. – Final speed: I couldn’t test it so far. Conclusion: If it remains that the consumption is lower, I can quite imagine to refuel BP Ultimate Diesel regularly in the future. The engine itself has become quieter when accelerating and the turbo noise is louder. Otherwise, no big differences to the normal diesel. More information is available at: www.bpultimate.at
