Kortom VPower98, hebben we hier niet.
BP Ultimate 97 ook niet. Dus wat doen ik?
Ultimate 98. Hogere compressiemotor, minder neiging tot (low &?) High speed engine knock/pingelen. Of wat?
EDIT, quote van een comment onder 't filmpje:
Higher octane fuels are NOT designed to provide higher performance. This is yet another video contributing to that myth. Despite their acknowledgment of the facts they go on pretending like they should see an increase in power, which is not the case. Octane makes gasoline more resilient to spontaneous combustion due to pressure. Engines with high compression ratios need higher octane fuels to prevent the fuel from igniting before top dead center, introducing knock which can quickly damage or destroy conrods and the crank. Octane does NOT make gasoline's combustion release more energy. The ONLY power increase you will ever see is in a vehicle who's ECU adjusting to make use of the fuel. These gains would be so minimal as to essentially be within any methodology's margin of error. This power increase will come from adjusted ignition timing, not from the fuel.
In the States (and possibly other countries) Octane rating uses the acronym AKI. AKI stands for anti-knock index. It isn't about power, it's about getting the gasoline to not detonate on the compression stroke. Buying premium fuels when your car is built for normal fuels is not only a waste of money, but in a vehicle that doesn't have the capability to adjust may actually be causing additional carbon buildup over time and causing problems. Obviously, the VW engine in this GTI isn't one of those vehicles, but the point remains.
Lastly, by using a different brand for every test they completely invalidate their testing. They should have used a high- and low-AKI fuel from each vendor and compared them against each other, not across brands. Seeing an increase in power using this methodology could simply be a result of gas quality across brands rather than Octane content.
