[QUOTE="440sprint, post: 12585226, member: 141283"] I read that Torco (MMT) may now be the preferred octane booster. I have a left over 3 gals of Mechanics Brand octane booster (57% tolulene, 43% ethanol, so I've read) from the high compression days about 20 yrs ago, stored in it's original 5 gal plastic barrel & kept sealed. It worked great back then but how about now? It may even be too old! Any ideas out there? Also, how much can I raise the 91 octane CA gas before it does no good without a tune? Thanks in advance for any help on this. [/QUOTE]
