Unleaded vs Super Unleaded
 

I been told to stop using normal unleaded in my scooby, or if I do to take it steady.

What do you guys use? You honestly notice any difference or is it all in the head?

As yours is an import, you really need to be using super unless it's been mapped for nul :thumb:

Standard UK WRX's no problem using normal unleaded, Imports and anything 'tuned' use super.

You should definetly be using V power or another super unleaded if its an import. Unless its been remapped of course! Fuel in japan is higher octane so they come out of the factory set up for it. Running a jap import over here on a lower octane fuel i.e regular unleaded is just asking for trouble.
