Thread: Turbo 108 Octane Booster in my 97 GP GTP Supercharged?

when you fill up on premium it's only like $2-$3 more per fill up.

That octane booster usually gives you a fraction of an octane or so, so instead of running 87, you would have 87.2 or so....

Ya it's seriously only $2-3 for premium. If really don't want to use it then I wouldn't go any lower then 90 octane.

It's a waste of money.

Octane booster usually costs more more than the difference between regular and premium.

Octane boosters do exactly what cop said, they add usually a tenth.

So, your 87 goes to 87.2, or maybe even 87.5 if its strong stuff.

If you aren't filling it with 91+ everytime at the pump then I feel sorry for that car. Boosted cars NEED premium fuel...always. Now if you are using 91 and add the octane booster I'm sure that'll help it a little, or adding it to some pump 92 or even 93. I always ran 93, hell I even run 91 in the N/A silver car I have. Why? Because these cars knock from the factory. Knock destroys these things. Look at it this way...

$3~ per fill up, or $500+ for a new bottom end.

Thoughts?

Depending on on how long you plan to own your vehicle. Say premium is $0.25 cents higher than midgrade, and say you put 15 gallons in the car. You would save $3.75 per tank of fuel. Times that by 200, and filling biweekly. You'd probably come out even..... or I'm just blowing smoke.

if the extra 2 dollars per fillup is hurting your wallet THAT bad, you should ride a bicycle OR if your too cheap to use the correct fuel for your SUPERCHARGED motor then you should buy a Honda



edited because i correct myself..i used 93 octane as required in my Honda Prelude

should have bought a gt/se

Run 93 and save yourself money. Octane isn't a power adder. Octane only prevents knock, which will prevent knock retard. If you don't knock on 93 adding octane isn't going to help.

But it's more fun replacing the bottom end. Filling up your tank with gas isn't fun at all.
