You add HEET to gas to prevent freezing and clean the injectors...One bottle per tank of gas is more than you would need IMO...

Why are you adding HEET to your gas when you live in a warm climate? I hope your not adding it to raise the octane because HEET is methanol and is used by the community for meth systems which injected would raise the octane for the combustion chamber.

I thought I read somewhere that you could use it as an octane booster Instead of buying actuall 100 octane

too much is bad for the fuel system. We have a suspect pump already, try to keep alcohol out of the tank itself.

Heet makes 104 octane booster that is mostly toulene. It is the best octane booster known and commonly bought in bulk at the paint store, mixed with mystery oil and gasoline to make high octane race fuel.

Next is MMT

Nitro Methane is another top notch addative.

NOS race formula gives me 3 degrees advance in ignition on 1/3 of bottle in a 1/2 tank of 93. So think 3 points. 93 goes to 96. A full bottle should take you over 100 but stuff costs 13 bucks a bottle. I save it for special occasions. Its a mixture of MMT, Toulene, and Nitro Methane.

Says BMW approved right on the bottle!

Has locations of all street legal sunoco 100oct unleaded race fuel stateside. Any location listed will have it available at the pump and it's around $7 a gallon here in ohio.

Where it the source for this info? It is totally impossible to increase the octane from 93 to 100 by a bottle of NOS octane booster.

60 pts as advertised. Thats 6 octane numbers so 99. Sorry for the leap their to 100

I am sure that you missed the 1/2 tank refference.... I know... your sorry.

[M3 Eater]

I guess if you look hard enough you can find independant tests that show that nos will only take you 98. So my statement can be held the +- 2 standard found at the fuel at the pump. Either way, I think its good stuff... and so does BMW.

Do you believe the HP increase that K&N promises too?

Food for thought when dealing with MMT (I work in petroleum business):

It is VERY corrosive. We had a 55 gallon drum with approx. 45 gallons of MMT and the cap wasn't screwed on tightly. Just the vapors from the one drum sitting in the bed of a box truck in the TX heat corroded the whole entire inside the the point we had to replace the whole box of the truck.
This note is found on the MSDS of the MMT we get
"In commercial practice the treatment rate should range from about 8 milli-grams (mg) of Manganese (Mn) per liter of gasoline to no more than 40 mg/L of gasoline. The US EPA limit for cars equipped with the latest emission control technology is 8.3 mg of Mn/L of gasoline. The limit set by Canada, and that proposed by in the latest Chinese gasoline specifications is 18 mg of Mn/L of gasoline. In those countries which have very few cars with catalytic converters, or in those gasolines that are designed specifically to help protect older cars against Valve Seat Recession (VSR), most countries allow a treat rate of up to 40 mg of Mn/L of gasoline, and the UK officially allows up to 50 mg of Mn/L of gasoline.

FYI I have an MMT calculation on my computer. If I enter 93.0 as the base octane, with 40 mg Mn/L (the max allowed and only for cars without cats) it only bumps the octane to 94.3.
If you use the 8mg EPA limit in the US, it brings a 93.0 up to a 93.6

I always used toluene and isoctane in my cars to bump up octane
Toluene is about 111 octane depending on what grade you get and very easy to come by
Isooctane is 100 octane and pretty much can only get it through my lab (very expensive also)

For shits and giggles I might even go buy a can of this and have the lab run it on the octane engines with 6 gallons of premium. I wonder how stretched the claims are.

PLEASE do this! I've always been curious!

I was having issues with timing, maps 8-11 on jb3 and meth injection. One day, I put in 1/3 of a bottle and went for a ride and all my timing readings were magically much better. Like I said, 3 degrees of ignition brings someone from a ehhh 7 (safe) to a 10 (optimal) though 2nd, 3rd, and 4th gears. If someone is currently using map 5 and is wodering how map 7 on jb3 will perform, I recommend the NOS booster race formula. It could be the difference between enjoying a few more hp and explaining to BmW what happened to your engine. Its not going to take 93 -100 but thats not really what its made to do. 1/3 of a bottle is the most I would use and I would expect 3 pts to 96. After that the returns appear to be deminishing. The nitro methane give the car an extra kick that I don't ever get with toulene alone and so thats why I like and recommend the race formula. If you are running more boost, dialing in your meth, and trying new, higher maps... its the cushion I perfer when race gas is not available. For those using meth.... the nitro methane compounds with the methanol to make horsepower above and beyond what typical octane boosters like MMT offer. Id love to see a version without MMT at all, Just toulene and nitromethane...Id be all over it.
