DQed in the S/S Semi for fuel in Dallas

[Ed Wright]

Just heard from Jared. When we towed up there from Houston the diesel generator in their motor home was not putting out enough to run their roof AC units for some reason they brought a portable gas generator for that. They had a jug of pump gas for it. He said he accidentally topped off the fuel cel with pump gas. In the excitement and rush he must have grabbed the wrong jug. Hate that for them. He was doing a great job.

That sucks. But it's also why I never put pump gas in race jugs

Ok, I know ahead of time that this is a dumb question. My wife and I are sitting here wondering why can't pump gas pass? Race gas is going to make you go quicker so if you make a mistake and put pump gas in why isn't it approved? It won't give you a performance advantage. Again, I'm new to the fine lines and don't understand what the big deal would be. ???

NHRA has a list of fuels that are legal for Stock and Super Stock.

Pump gas isn't on that list.

Rules are rules as AB said in his interview, 3.22 reg gas here in NC, and that RACE car had a awesome package, how does this happen?

[Ed Wright]

And, when you tell them it is "C11" "C12", etc , it has to check between certain numbers at a given temp. If not it is illegal.

My pit vehicle and portable gen all run on C11. One less thing for an old man to mess up.

al my engine builders told me if u wanta burn a piston put some cheap gas in it! Its a crazy world we live in and NHRA tech is amoung them!

[Darrin Christen]

That's a tough deal for sure. Do they normally check fuel in the later rounds when it's not a heads up run? Those last two rounds were some tight packages, especially the final!

Some pump gas, as is sold here in arizona for example, are "oxygenated".
From the EPA:
Oxygenates are fuel additives that contain oxygen, usually in the form of alcohol or ether. Oxygenates can enhance fuel combustion and thereby reduce exhaust emissions. Some oxygenates also boost gasoline octane.

The Clean Air Act requires use of oxygenated gasoline in areas where winter time carbon monoxide levels exceed federal air quality standards. Without oxygenated gasoline, carbon monoxide emissions from gasoline-fueled vehicles tend to increase in cold weather. Winter oxygenated gasoline programs are implemented by the states. The links below provide information about oxygenated gasoline, winter oxygenated gasoline areas, oxygenates (such as ethanol and MTBE), and health effects testing of oxygenates.

Basically pump gas that has been oxygenated has qualities that are similar to those banned fuels unacceptable to NHRA. Since field testing is not able to decipher the exact recipe's used in the fuel being tested, if it a fuel check reveals certain properties, it's no good.
Now, proper field testing is a whole 'nother story.

Ok, that makes sense now. Thank you for the explanation. I didn't understand why something would be banned that could actually hurt performance but now I see. I appreciate it.
