i egree, they just found enather way to fool ppl. Anyways there is one thing you kan do. It posible to find a chemical that reduse friktion in motor and gearsbox, diferentual - if you have that. You se where im going? Las friktion, las fuel. not much realy 10% tops

personally, i'd rate a good octane booster to the way something like 93 octane would make your engine run. i've used lots of addatives and tried out different grades of fuels so just from what i've observed on my cars. so octance booster dont waste money on it

The only reason to run octane booster is if you're tuned to need something higher than 91. We've already discussed how running a higher octane is pointless if you're not tuned for it, so of course octane booster isn't going to do anything for you.

87. Cant find anything any lower or cheaper!

same here. anything more would be a waste to me.
i wouldnt think of premium fuel unless i had a souped up engine
