octane boost

[hawky1]

hi i have a 328is . has anyone ever used octane booster in their bmws and do you notice a difference in performance. i do use premium gas with i think 91 or 92 octane . ive heard that the engine runs cooler with it. thanks in advance.

im actually gonna try the NOS race octane booster, apparently it raises the octane 70points (7octane numbers). but im also curious to see what the Lucas octane booster would or will do as well

Its weird, im guessing you guys are from the states.
In Australia

Normal ULP : 92 Octane,
Premium ULP : 95 Octane
Vortex / BP Ultimate : 98 Octane
Ethanal Pulp : 100 Octane

General Costing

ULP : $1.20 / Ltr $5.40 /Gallon
Pulp : $1.30 /ltr $5.85
PPulp : $1.35 /ltr $6.00
EPulp : $1.45 / Ltr $6.50
Dielsel $1.40 / Ltr $6.30
LPG : $0.55 $2.45

Not sure why the ethanol one is so expensive, as the goverment cannot put an excise on it, and for the moment ill stay with Vortex

engines do run slighly cooler with higher octane levels since the higher the octane the slower the burn...the longer the vapor stays in the combustion chamber the better the cooling effect...make sense

ive used them before... never noticed any thing...

i think your using the wrong ones crusin, i did some research on them , and talked to almost all the leading companies that make octane booster, id say almost all only make only 1 octane number (10 points) or less.. i mean most dont even create an octane number.....its sad that they rope in consumers by using points. this NOS octane booster says it raises the octane by 70 points (7 numbers... so 91 octane will go up to as much as 98 octane)

the reason i use it is to fight off engine knock, if i get a bad batch of gas , because with the SC im safe using 94 octane but 91 octane is risky, i have it on hand in case i do experience knock.

i cant really say octane booster is good or bad, because i really dont have enough experience with it.
