This is one of those subjects that has many opinions. Mine is that I run 107 LL through mine all the time and it runs strong no problems, the only issue is it will burn the O2 sensor right up, so just get a Denso and don't worry.
I know there will be alot people on here that will say just run race gas, c16 or whatever, well if your like me AV gas gives me almost the same performance that race gas gives without the cost($1.25 gal VS $6.00 c16) and I can get it right by my house. HTH
