Why does it confirm that? Has anyone tried a dyno rather than hearsay or their own opinion to compare 98-octane fuels?




David

A dyno is certainly useful for comparing maximum power capabilities of each of the fuels but often when you're driving it's the part throttle response and smoothness that are noticeably different. That sort of thing is hard to quantify on a dyno so the old "seat of the pants" dyno is what we are left with. One of those hub dynos that are very sensitive would be useful for this sort of thing.

Having said that you really have to wait for more than one tank to make any conclusion. Sometimes you can feel a difference week to week even when sticking to the same fuel.
