Octane Booster Good Or Bad?

[KyuubiGTR]

Hey all just wondering is it ok if you run octane booster on every fill up I've got an r32 gtr stock boost, yellow top injectors and some form of tune

[Sunkist]

I wouldnt, they dont do anything noticable. just fill up with 98ron "premium" you'll be fine.

im sure theres a thread about it, perhaps search may help..

heard mixed opinions on it - have used it once - didnt really make much difference

Better to use 98 if possible. But if you cant then octane booster is prob a good idea.

98RON is a lot cheaper then 95 + octane booster

Sweet cheers lads=)

They don't do much, unless you use straight Toluene in large amounts. Naphthalene (old ingredients for mothballs) works a bit as well, but I think it will do more harm due to them having a tendency to crystallize very easily. I use Toluene and Naphthalene simply because we have only 89 or lower octane There is a big difference in power, and exhaust temps when using Toluene. Don't see much difference with Naphthalene, exhaust smells horrible, and need to dump Acetone for removing possible deposits every oil change. If my engine breaks, I'll be sure to let you guys know

You're correct that Toluene (aka Methylbenzene) will increase Octane and RON much better than the booster bottle.

Caution:- Methylbenzene is highly carcinogenic, so it must be added outside and downwind from your face.

i believe unless ur car tuned for it, there is no use increasing ur octane number..

the only benefit from filling up 98ron to 95(skyline recommeded gtt) is that they are more dense talking about bp here specifically, they claim their 98 is denser

which basically means u get more fuel when u pump.. remember good old yr 12 physics density = mass/volume.. so adding those pills is practically doing nothing in this sense.. might as well eat ur money or better spend it on some other pills..

except to stop the knock!

if the car is tuned for 91 ron fuel (like most NA cars are) then you shouldn't be getting any knock running 91 octane fuel, unless the car is leaning out due to a fuel system issue (blocked injectors, lines, filter, or dying fuel pump), or the fuel timing has been advanced or some sort of mechanical issue (such as hot spots in the cylinders). if you were to advance the timing when you put the higher octane fuels in then you will see gains, but if you run it dead stock then you won't see any gains.
