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....
