Octane Booster

[de bong]

Hi all,

do you guys use any octane booster for your jap motors as it is very hard to find anything above 95ron where I live. If so what kind?how much does it cost you?would you use it all the time or just every few tanks?

Thanks

I use Octane booster in the Impreza, need to as the car was designed to run on 100 Octane fuel.

I use Millers CVL, but it's not recommended for car that still have Cats fitted

If you have a cat then use the Octane plus instead.
