True, I guess it really made the difference for the one or two stops I made and overtaking all the time, it discouraged the kind of acceleration I would have loved to use
Funnily enough, the way back was an average of 6.1, same road, so might have been the 95 vs 98 octane fuel, elevation, or just the heat (or a combination of them all)
Either way, still an amazing result for me
