Sunoco’s Zachary J. Santner has been answering our fuel questions for years, providing us with straight, science-based answers. What fuel for more power, better storage or an older engine? How to best store fuel or what to know about making the jump to E85? He’s happy to share.

You can now ask him your questions in person: He’s in Sunoco Race Fuel’s SEMA booth the rest of the week–booth 20567 in the Central Hall.
