Whats Better

i recently tried peak98 and im sure the knock level was lower on the PFC when giving the car heaps, i could just be imagining it though, but it definately seemed lower, couldnt really notice any difference in drivability.

im all about what ever is cheaper but now that caltex has realeased 98 vortex i use it over bp just coz my mum shops at woolworths and i get 4cent off a litre.. im a pizza boy every cent counts in the quest for more power
