100-Octane "Race Fuel" at a Chevron in L.A. ??

BarryJI · 08-21-2018, 12:15 PM

A local east Los Angeles Chevron station is getting a big makeover and is flying a banner announcing the imminent availability of 100-Octane "Race Fuel". I am curious what you make of this, bearing in mind that you can't even get 93-Octane here in Southern California (91 is the highest available). This gas station is nowhere near a race track. I would like to use the highest quality fuel I can get but are there any risks in "upgrading" to 100 from four years of 91? Is it to be trusted?

I'm reliably informed by a race shop that specializes in BMWs that it won't do anything more for you than would 93 octane. So while it's a viable alternative to running 91 and would provide you with 93 octane-level power, you'd likely have to pay quite a bit more for it.

There are no risks in making the switch from 91 to 100 - the ECU will make the necessary adjustments. All you should notice is somewhat more power, and that's if you're leaning hard on the car.

My guess is that if it's labeled 100 octane and it's being sold at a Chevron station that, yes, you can trust the fuel. For years I bought Sunoco's 100 octane in New Hampshire for $8/gallon - always the same price, no matter what was going on with the price of the regular blends. Go figure.

This is very useful info, many thanks.

Since you don't have regular access to 93, why don't you use the 91 and mix with maybe a few gallons of 100 to up the octane. This method will raise the overall octane of your entire tank. I'd personally add in one, or maybe up to two gallons of the 100 per full tank.

for you 91 folks, this is awesome. problem will be cost, probably 10- 12$ per gallon like all the other pumps with 100 or 110.

Race gas is super expensive, and you won't notice much power difference unless you are running a tune that will really take advantage of it.

If you are running a tune, you probably only need to mix in a few gallons to bring the octane up to 93-95. A far cheaper option to bring up your octane, is to put in a couple gallons of E85 instead. There is a Chevron off the 5 at Roxford St. (Sylmar?) that has E85.

There are calculators you can google to find out how much 100 octane race gas or E85 to mix in with your 91 gas to hit the octane you want. You probably need about 3 gallons in an M235 with its small gas tank.
