Race Gas

azhodge · azhodge's Garage

anyone have any thoughts on "Race Gas" race fuel concentrate? cannot get ethanol free 93 octane in my area. One ounce per gallon raises octane 4 points. I can get 90 octane in my area.

4 points is a misnomer. It doesn't raise your octane to 97, it raises it 4 basis points. This means you get to 93.4 octane.

four octane then.

One bottle of any octane improving additive will not get you to 97 octane is my point...unless it comes in gallon jugs. What you're talking about will only get you to 93.4 octane on the first bottle. 93.8 on the second, 94.2 on the third, etc.

For example, my last road trip to CA, I was using 3 bottles per fill-up to get to 92 octane.

I am looking for opinions on "race gas" race fuel concentrate. if you have no experience with it, and are not willing to read the info on their website please save me the lecture on "octane boosters"

Kenik is a pretty sharp guy and he's offered some excellent advice!

Octane boosters, ALL, are generally a waste of money and a damned expensive way to boost octane. To me, they are only to be used in emergencies when 91 or better fuel is simply not available.

Just saying, there are only a handful of chemicals that are legal in pollution controlled vehicles to raise octane. "Race Gas" is a brand, not a technology. It is not a magical elixir that is exempt from the laws of physics, thermodynamics or economics. There's a reason 100 octane unleaded race Gas is $9/gal. That reason applies here both explicitly and implicitly.

At $30 for 32 oz, that's $60 per 18 gallon tank to get to 99 octane. That cost correlates 1:1 with race gas prices and over the counter octane boosters. Reading more, it sounds legit, albeit expensive. I'd still like to see the MSDS.

Hi boys.. i am surprised nobody is mentioning the Toluene..i used to get it at any paint shop when i lived in LA..it works great and people use it in racing...one gallon(10$) to half a tank will do the trick..

Toluene is really hard on seals and has gotten REALLY expensive as well.

About a year ago I asked a similar question:http://forums.pelicanparts.com/911-930-turbo-super-charging-forum/904789-octane.html
After more research I decided I would be ok with the 90 octane as long as I wasn't racing or going for high boost numbers. I have twin plugs,cis and keep it on the rich side.

Unless you've replaced them, the rubber o-rings in the fuel head. Toluene can swell and degrade these o rings.

Aha, there you go. The only other concern would be if then polyamide fuel lines thru the tunnel are toluene soluble. Don't know the answer to that...

100 LL (low lead) Avgas works pretty good, about $4.50 at the local FBO

Not sure where Brookhaven is but maybe one of these places would work for you:

Cam 4 would be a good alternative but you have to remember that gas stations are not allowed to let you or will not pump that into your car if you drive up to it. So you options become trailer the car to the gas station or take gas cans to the gas station both of which will be a huge pain in the ass, not to mention you will be paying up the butt for gasoline. Your other option would be drive to a track to buy gas from the track or get your gas from a marina but if you don't live near either, you're screwed. To me, all those things seem like a lot of work anyway. There are no ethanol free gas stations in my area (believe me, I've looked) so what I do is just add a treatment of Sta-Bil in my car's tank whenever I refill. You can get the one that is specific to ethanol but I use the marine formula because those guys are squirrellier with their boats than we are with our cars and those engines have limited use like mine has. I hope this is helpful to you.
