Octane booster, which one?
 

My mate and me both suffer with the same problem, the nearest v power is a 30 mile round trip from us.

He recently bought a blob sti and its mapped for vpower so wants to keep some booster on board in case he's caught short.

What do people recommend?

I saw some BP stuff in Halfords that adds 2 points and didnt require a lot, so the bottle would last a good few tanks but i've not seen it mentioned.

I use the NF stuff supplied from Alyn AS Performance
