With high c.r. like LS6 and L78 and even a Stage 1, it would always blow a baffle loose in a stock muffler. At the time we had a small municipal airport and no one cared if I pulled up to the pump for LL100.

Later I read info that the problem was caused by the LL100 being too "hot" or too "dry" and therefore caused the problem, but not enough detail was given for me to understand what that meant.

Hi Mike. In 25 years of racing the SS'er I only failed with C-11. Once we had to take an entire drum back. Hot, muggy, hi humidity tracks was a problem for us and C-11 plenty of times. We never took the fuel out of the car after races, and it had a plastic Jazz cell. Maybe if we took the C-11 out and stored it in steel cans it would have helped. But C-12 never failed along with C-25, all the Sunoco fuels, even while leaving them in the plastic cell for extended timeframes. We did of course take the ERC out. Even after swapping ERC with anything else, our house smelled like ERC until the underneath was wiped down. That stuff STUNK>>>>
