NOS Octane Booster?
I was thinking about getting a bottle of NOS octane booster but i am unsure if it will harm anything or not. It raises the octane rating 6 points and i use 92. Will that cause any problems or will my car just be more of a beast after i use it? Any opinions?

the TL is designed to run at its best on 94
more wont do you any good, wont make the car faster to make a higher octane blend
and may cause some problems as ecu tries towork with higher octane-adjusting timing etc
run seafoam thru the gas at half tank to full can to make car run better everyday

Yeah Octane boost will only work for that tank. So if trying to get better times at the strip, it will do that. But in my experience, in building SCCA cars we used 106+ octane booster(which would raise 91 to 106) it forced the ECU to, correct me if I'm wrong, run alittle on the lean side along with adjusting the timing. And no damage was done to either the ecm or the motor itself. Our Type-S compression is 10.5 to 1 where as the TL-P has a lower compression @ 9.8 to 1. The Higher compression calls for Higher octane. 91-94
If your looking to clean fuel system then follow the DIY's on seafoam or use some lucas fuel system cleaner.

Octane requirements are based on what your engines require.
Engines can adjust down but not adjust or use up.
98 {92 + NOS} is too high for TL factory engine timing.
At best it will do nothing but throw your money away.
At worst it will cause LT damage.
Keep in mind that ethanol in pure form {105 Octane} also increases gas octane but it increases corrosion and lowers explosive gas power. Consider the 25 % ethanol used in Brasil
and the engine problems there.

we are back to:
how many gallons of what octane fuel-will a bottle raise to what octane?
That can of 106 didnt treat 15 gallons!!
(I am a Pilot-= we know gas!)
I thought type P was 10-1 and S are 11.5-1 compression?
both are ecu programmed for 94 and will accept a `Minimum` 91 octane
A normally aspirated engine- meaning without supercharger or turbo:
will not benefit from running way higher that spec octane
It just doesnt happen- basic physics are involved
Add a pressure intake system= and octane becomes all important!!!

sidenote: Ethanol (E10) means 10% ethanol added to our Premuim 91 fuel in the usa
(and the govt has approved e15 for newer cars-will be in stations in a few years)
While it does raise octane, to reduce predetonation (thats what octane does)
it also burns less efficiently- leaving horsepower unproduced, and creating a lot of unburnt combustion residue,,lowering overall mpg
Everyone can stand a good treatment= at max dose- of seafoam or bg44 or lucas thru the gas twice to clear all the old crud out

Plus the higher the compression, the need for higher octane. But the fact of the matter remains. If your not running at the track, you don't need anything higher than 91.

94 is certain states/areas,,thats their `91`
there is an advantage to 94 over 91
as the ecu and engine are made to work on 94 and will adapt down to 91 and still run decent,,since much of the country has 91 as its highest
On a cross country drive I found 94,,think it was higher elevations
Denver or mountain people can you verify that?

in the US octane rating is displayed in AKI. In the Rocky Mountain (high elevation) states, 85 AKI (90 RON) is the minimum octane, and 91 AKI (95 RON) is the maximum octane available in fuel[citation needed]. The reason for this is that in higher-elevation areas, a typical naturally aspirated engine draws in less air mass per cycle because of the reduced density of the atmosphere. This directly translates to less fuel and reduced absolute compression in the cylinder, therefore deterring knock. It is safe to fill a carbureted car that normally takes 87 AKI fuel at sea level with 85 AKI fuel in the mountains, but at sea level the fuel may cause damage to the engine. A disadvantage to this strategy is that most turbocharged vehicles are unable to produce full power, even when using the "premium" 91 AKI fuel. In some east coast states, up to 94 AKI (98 RON) is available.[23] In Colorado as well as parts of the Midwest (primarily Minnesota, Iowa, Illinois and Missouri) ethanol-based E-85 fuel with 105 AKI is available.[24] Often, filling stations near US racing tracks will offer higher octane levels such as 100 AKI[citation needed]. California fuel stations will offer 87, 89, and 91 AKI (91, 93 and 95 RON) octane fuels, and at some stations, 100 AKI or higher octane, sold as racing fuel.
