Octane boosters in a can arn't worth it IMO...
The ONLY Octane booster that can really be used (with optimax as well) is Toluene.
10% mix to your fuel.
Toluene is 114 octane so it ups the 98.5 of optimax to nearer 100 octane.
Millers, silkolene etc just too small a bottle to have any real impact IMO...
Having said that Optimax on its own is what I use unless I'm going to the track...but really I'm just buying optimax to try and win something on the scratch cards!!
