Turbo Blue Racing Gasoline...

So I was filling up today at a Sunoco station with 94 Octane, and noticed an extra button for something called Turbo Blue Racing Gasoline. The button said it was 110 Octane, and it was like $3.50 per gallon.

Now, I didn't think of putting it in my 325. (Ok, I thought about it for a second ).

What's the deal with this stuff? This was a major retailer selling it, so I don't think it was snake oil. Any pros or cons (besides price?) Would you really feel the difference? Wouldn't this screw something up with 02 sensors, etc....
Has anyone heard of such a thing?

Probably won't see much without major modifications. That stuff is best used in high strung race prepped engines, like high psi turbo/sc systems, or naturally aspirated engines with much higher compression ratio, where engine knock is an issue at 93-94 octane. It would possibly make a difference on an M engined vehicle, but I don't know how perceptible the improvement would be without good measuring equipment.

Something as high as 110 is usually leaded fuel... run that over a prolonged period of time in a street car and you'll clog your catalytic converters. not good.

You could get this stuff from a regular pump? Another Sunoco dealer in Michigan had a separate pump for 110 and monitored it to make sure that it wasn't being pumped directly into street vehicles. Rumors persisted about people showing the attendant a 5-gallon jug before he would turn on the pump, whereupon they would back their '75 Chevy Nova up to the special pump, pop open the trunk, and convince the attendant that they were *really* filling up the jug, not the car. Or so I've been told.

I use to run that stuff years ago in my motocross bike. Definitely performance gains in a two-stroke engine… I don’t know about our cars. The smell from the exhaust alone is worth the cost!!

It means you have a race track nearby! IIRC it is 115 octane. The Blue part of the gas is just a dye, and it tends to coat your fuel intake area. We ran this in a race car with a carb about 10 years ago and the inside of the carb turned blue. It is meant for higher compresion race engines that have no emissions systems left on the car. And it does smell really good!!! Another similar gas is CAM2 racing fuel, I think it is 110.

I just found out today, that the local Mobil station sells CAM2.
I checked out the pump and it says 110 octane, off road use only.

But I'd like to know if can mix with street fuel to boost up to 98, which is what I believe stock BMW's are designed for.

I'm really curious how the stock 3.0 liter runs on the good stuff.

Any fuel experts out there?

a) 98 octane in Europe is 94 octane here. They use RON, We use RON+MON/2.
b) As they said earlier, 110 octane is leaded. DOn't even think about trying it.

Thanks for the update. I was looking for a cheap thrill.
I guess I'll keep hoping for an M3 some day. If only my local dealer would come off his price on the leftover 2004 M3 in his show room! I keep telling him it's depreciating, but haven't been able to work a trade with my X3, that I can live with.

Are you guys sure it's leaded? If so, I might look for it in my area. I have a 1970 TR6 PI that was originally designed to run on like 98 octane leaded. I bet it would love that stuff...anyone know if any place has it in northern VA?

103 is the highest unleaded rating I've ever seen... anything more and it has always been leaded racing fuel.

Sounds similar to the fuel used for piston engined airplanes (avgas),

I'd definitely worry about the lead. "100 low lead" avgas has way more lead than leaded car gas ever had.

100 low lead is also dyed blue, so it won't be confused with other types of fuel.

For more info, take a peek here:

It does give a kick

I run a 50/50 mix of CAM2 and 93 octane twice a year in my 1994 Firebird Formula. It gives the car nice pick up and I agree it smells cool. No problems with the car 4 years later. The CAM2 is leaded.
