@johnny5, lucas averaged just shy of 98ron while being run on 20 cars being mapped NOT 97 ron. why not just get your cars mapped to half a bottle of lucas and see the difference that way. i did and i can tell you it was the best money spent by far on the wrx. highest knock reading was 13, boosts to 1.2 bar peak and holds to 1.1 to red line and thats running a small td04 turbo. but thats just my opinion on the matter, and if i had the money to experiment on other fuel additives without feeling to bad about the risk , like i said i'd rather spend it on a remap. cheers
