V-power in preference, Momentum if it's not available wherever I am.

I recorded knock with Momentum on track days and none with v-power. These were days when I arrived with a full tank of one then deliberately filled up from practically empty with the other. Same conditions through the day (air temps, laps done etc)

A significant issue with Momentum is it regularly has a higher ethanol content than v-power and ethanol absorbs lots of water over time.

I believe Tesco don't sell much of it at each station (have you noticed how long sometimes the pumps take to get going?) and absorbed water lowers the RON of the fuel.

That's my thinking on why I've gotten more knock from Momentum every time I've logged my car under decent load.
