how high of an octane booster can i use and not have to worry about hurting the engine which has stock pistons and will i notice any type of gain?

 

oh geez

 

Uh-oh.


OP,

Let me save you some trouble before someone else says it with less...er....Christmas spirit.


Search it.

 

this is not a good question to ask. Any octane booster will prob not bring your gas above race gas. You will be fine with any of them, but nissan recommends that you do not use fuel additives.

 

*facepalm*

 

103

 

Oh boy here we go................

 

Basically buying an octane booster is not worth it. Save your money

 

don't waste yout money. it is nothing you would ever notice anyway except being a bit lighter in the wallet


and before you ask, you can not use 89 octane gas + an octane booster to get to premium grade. no matter what you do to it it will still be cheap gas.

 

The problem is the octane is speced in points, that means 1/10 of an octane point [ the wording is designed to confuse the non engineer] so you must add 10 bottles per 10 gallons to get meaningful change............roughly a gallon of additive to 10 gallons of gasoline. Same thing with toluene and xylene.

In the end it's cheaper to just buy racing gasoline if REAL ACCURATE NUMBERS above 91-93 are required.

Manganese and Ferrous [ organometallic] additives will foul spark plugs and cat convertors.
