Fuel check question - Page 2

There is nothing wrong with Sunoco Race fuel.
Purple can be a little inconsistent due to wide tolerance in processing. Blue and up are very consistent in production.

Some say other brand fuel is faster but that depends on number of things.

Have run Sunoco purple in my cars for years, blue last season becuase of ease of availability to me and cost. Have had issues with fuel check on and off for years. Had a big deal at Englishtown points meet 2011 have had enough of that.

As I said the fuel is good, the culprit is how the fuel is handled before getting in the hands of the racer. It's not a national problem.

The safe way is to install a fuel cell (PIA), buy fresh fuel at the track when racing NHRA. If the fuel being sold during the race is bad it's not the racers' problem.

A fuel sample valve can be found at Jegs, Summit, etc.

For info on racing fuels stability, do some research at the fuel brand websites.

If we were to change the test level from the halfway point to 3/4 way, that might help some who have old fuel but it would also give more leeway to anyone looking to enhance their fuel.

VP110 was on the accepted list a few years ago but has since been removed. I do not know why.

They have always tested like that. Hope that helped or Im just full of *****........

Bob, What end of the scale would $3.00 pump gas read on? Av gas? That could be your answer right there...

The problem I have had in the past here in Div 2. When I go to check fuel and its anything besides VP the fuel check guys give me a hard time. They say the color is wrong or something like that. I either run sunoco blue or C-12. I think they just want you to run the VP fuel.

Ok... two part question here. First is there a tool that the average racer can buy to check his own fuel so that you don't get a surprise from tech? Second, what is the best/most common what to retrieve your fuel for fuel check? Are you guys just opening up the fuel cell and scooping a cup out?

I have always wanted a stocker, and still do.. but reading this about the fuel, who knows if your gonna pass teardown stuff scares me to death.. I think I will just keep bracket racing... I couldnt spend the cash to go to some of these races not knowing if my fuel that I purchased there is going to pass or not... Not knowing if I am gonna get the tech guy who interprets the rules the wrong way...

Why do you guys punish yourselves this way?? LOL Are they wanting less racers at the track or ????

I've had C12 check fine after being in a vented, pvc half full fuel cell for 6 months. As far as tear down goes it's up to you to leave a little extra. If you make all your specs meet their specs there is zero room for error.
I remember when we had the hemi car. We would have to hit the top of the piston with a hammer to knock the oil out of the bearing. And we would ice the head to get it to check CC's. Was all of this needed? I doubt it now, but at the time we thought it was the only way to go fast.

If I were to ever get a stocker it would be legal.. Might not be stupid fast.. but it would be legal.. lol

Racing gas testers are "fairly" expensive---around $450-550 for the Digitron which I believe is what NHRA uses---weather/humidity/temperature/additives ,evaporation, exposure to light,type of storage container etc are all things that will affect the outcome of the test---cleaning the sensor tip in unleaded gas after every sample/reading is mandatory after each use------Travis is right listen to him!!!!After you purchase your new batch of gas it is wise to have it tested for "legality" BEFORE you put any in your vehicle---saves having to hafta clean out the entire system a sometimes costly and time consuming project--FED 387
