Don't put a whole bottle into 30L of fuel .
It should only be used as a knock deterent ! Not as a power adder .
I just tried some Powerplus 102 fuel last week with some good results . Yeah it's not cheap @ $103 for 20L , but pump gas is just too inconsistent nowadays for my liking :/
Pump 98 & Octane booster I ran 114.5-112.6mph :/ too much knock and timing gets pulled .
On the Powerplus 102 ( 20L mixed into 18L of 98 & OB , will run straight 102 next time ) , the car ran consistent 115.1-115.6 mph all day . 25 deg heat .
So yes octane booster can prevent detonation , it's no real power adder compared to some decent fuel . If your not racing that often , $30 for octane booster vs $100 for some good fuel , cheap cheap .
Then again , E85 Cheap cheap again !
