Race Fuel Question

Sean Marconette · 01-18-2014, 06:09 PM

I have never ran anything but Sunoco Purple (110). I have never had any fuel check problems in Divisions 3, 4, and 5 with tech saying anything about it even being questionable on passing. For the cost it is the way to go for my car.

Sunoco will pass fuel check. Buy it in quantity and be sure it's fresh. Rick told me Sunoco finally updated info to NHRA last year, all should be good at fuel check.

Your engine will run on Purple but Blue is faster burning and more consistent batch to batch. Spoke to engineer from Sunoco a few years ago at PRI when doing some research. You will need to change your fuel and timing maps.

The best thing to do is buy a drum from a good dealer and store it properly. The fuel will not degrade for a year if in closed metal container out of heat and sun.

Hope this helps.

When I ran my LT-1 Firebird......in 2006-2007

I had C-12 fail and it was fresh from the tracks supplier that very day and came out of a new drum..... at Cecil County. A lot of guys had issues that day from what I saw....
I also had Sunoco purple fail up at Lebanon Valley.....I brought it with me and it was fresh...

After those two incidents I used C-11 and drained my fuel cell before going to any NHRA race. Bought fresh fuel when I got there. C-11 always passed. It was no faster.....and the fumes in my trailer were terrible from it...

In 2011 Larry Pappas let me race that car (he owns it)and I ran it at Island the week before the Dutch....I used Sunoco purple and ran it all day.....went to the final of a gambler race and made about 7-8 runs.....very consistant and ran well for the weather,

Went to the Dutch.....drained the fuel and put fresh C-12 in it....Passed fuel check no problem and ran a little faster but it was more the weather and the track than the fuel making it faster. Maple Gove that time of year is generally faster than Island by a good amount.....I went no more than .05 faster....

An Lt-1 has over 10-1 compression with aluminum heads.....

The only reason I ever used C-11 was because it always passed and C-12 had a reputation for failing......as did the Sunoco purple....

The LT1 compression is on the high side of what they recommend for C11. Tuning for it showed me a little. This past year I had 5 gal left over from 2012. Took a sample to be tested at the first 2013 race. It passed just fine. I went ahead and used it. Fresh fuel ran exactly the same. As with the Sunoco, it likes it's own tuneup. I can make mine run a tad quicker on C11 than C12 or Sunoco. I really like the zero fuel check issues. C11 costs a little more, but what is cheap about this anyway?

Ed, I use C-11 Now Myself. Just wondering if that's Overkill for a 305 low comp motor is all.
But, if their are more issues with Sunoco than i'll stick with VP.

And your right, theres nothing cheap about racing, (only the pay-outs )

I get Sunoco race fuel from a gas station that pumps it from the ground, it's about $8.50 a gallon, I've had it sit in a container for over a year and loose it's color, it still passed NHRA fuel check. I was told to put some fresher fuel in the car just to get the color back. Never had a problem passing with Sunoco. I went to the PRI show a couple of years back and asked the Sunoco representitive how long the shelf life for the fuel is, he told me that it was just about 2 years.
